Ways to improve your WiFi

Great home WiFi is an asset, but its really showing its greatness during our COVID-19 times. While most of us are relying on it more than ever, many of us don’t have WiFi that’s very good. Since many of us are working from home or our kids are now taking their classes on-line, poor WiFi has become even more apparent. There are ways to improve your WiFi though.

Improve your WiFi with upgraded equipment

Long gone are the days when most of us can rely on the WiFi equipment from our Internet provider. Our insatiable appetite for data combined with the sheer number of WiFi connected devices in the modern home means that our WiFi equipment needs to be up to the task. Unless you have a small place, this likely means a good router with multiple WiFi access points in your home (and outside if you need WiFi out there too).

  • If you have a newer, well technology architected home with networking wiring in the walls, you can use a dedicated network router wired to the WiFi access points. A good router has better ability to move the data in and out, and around your home – both wired and WiFi.  Internet provider routers can’t properly handle modern loads. The separate WiFi access points are then installed strategically around your home to provide coverage where needed.
  • If you’re not one of the lucky ones with networking wiring in your home, then you can use mesh WiFi. As mentioned previously, mesh WiFi is made of nodes that talk to each other to create a network. Its sort of like a WiFi version of the children’s telephone game, but the newer equipment, like the ones from eero, work quite well and the messages get through.

Improve your WiFi by tweaking what you have

While upgrading your WiFi may sound great, it might not be possible due to budget or that you can’t actually have someone come into your home during COVID-19 to install better gear. (This is looking up though as restrictions are easing.) Here’s a few things you can try:

  • Move your WiFI router closer to where you need it. People often put WiFi routers Choose a good location for Wi-Fi routerin a back room or in the basement, so unless you’re near there, it doesn’t do you much good. Your home’s building material makes a big difference too. You likely aren’t going to get very good signal if your walls are made of concrete or metal studs. Perhaps temporarily moving it centrally for better coverage is worth the tradeoff of it being an eyesore.
  • If that’s not an option, or you’re not into that sort of aesthetic, maybe you can try a place in your home where the WiFi is better. You can check WiFi strength using the Airport Utility App on an iPhone, or Wi-Fi Analyzer for Android. While not a perfect WiFi-o-meter, these can give you a picture of your WiFi. If you can get -60dBm or higher, you should have decent enough signal to get things done.  (Note its a negative number, ie -50dBm is even better.)
  • Reduce the number of WiFi devices activity trying to use WiFi. Many WiFi routers can only properly service 20 or so devices. Once you count all your family’s phones, tablets, laptops, smart watches, eReaders, thermostats, smart TVs, smart lights, etc., you can quickly amass a mess of WiFi devices that all need to be serviced. While we think they’re all getting a connection at the same time, they’re actually taking really quick turns. When it’s not a device’s turn, it has to wait without data. This really slows down for WiFi routers that can’t handle lots of devices well. (Fun fact, even devices not on but near your WiFi can slow it down.)

Deeper WiFi tweaks

If you’re feeling savvy, you can try some more involved changes:

  • Change to the 2.4G WiFi – even though most advise to use the 5G WiFi signal as it has faster data. While this is true, 5G WiFi doesn’t transmit as far as the 2.4G signal. You might be better off sacrificing data rates to actually get usable WiFi signal coverage. WiFi routers also have a propagation pattern for their antennas (ie the 3D ‘shape’ of their WiFi coverage). If you can find it for your router, you can try to orient it to favour your needed WiFi spots.
  • Change the WiFi channels. 2.4G WiFi has 11 channels available, but usually only 1, 6, 11 Improve your wifi changing channelare feasible for technical reasons. If you and your neighbour are both using the same channel, then you are getting in each other’s way. Changing to another channel will improve your WiFi. With only 3 useable channels, its obviously difficult to stay off of your neighbour’s channel in places like apartment buildings though. 5G has more channels, so you should be able to find a space there. With 5G, you need to worry about the signal coverage as noted above though. If you have more than one access point, make sure they’re not using the same channels too.
  • For setups where you have more than one WiFi access point, adjust the power levels. You might think that its best to turn up the transmit power to max, but that makes it harder for your WiFi devices to decide which one to listen to. You want to set power levels so that device like iPhones naturally move to better WiFi when its available.

WiFi is complicated

WiFi is a complicated beast, but you can make some adjustments to help get you through these trying times. It does seem a little bit like black magic though. So it might be a good time to consider professional help and equipment to get your home network up to date.

 

Sonos cuts support for older devices, then backtracks

Sonos received an Internet smackdown this week when they announced that they were going to stop supporting old equipment. Some of the backlash was because it wasn’t clear that support was being dropped for systems with really old products only, but the damage was done. In the end they apologized and backtracked, but will this be a good thing for Sonos users? And what is a reasonable expectation of manufacturer’s home tech support of our favourite devices?

What happened?

OK, so what is this all about then? Sonos announced that they will stop software updates for some Connect and Connect:Amp (plus Gen 1 Play:5) players. If your system has one or more of the affected products in it, your whole system would have been held back and would not get software updates. Sonos likely made this hard decision so they could keep offering new features people want, and the old gear needed to be culled to allow this. These products just didn’t have the horsepower to keep up the home tech support of features like voice control and smart home integration.

To ease the pain and get you on their latest gear, they’re offering a 30% discount to update your gear. The media and Internet haters missed that only the really old gear is effected. Even if two pieces of gear look exactly the same on the outside, they’re not the same.

Underneath the covers

Like many manufacturers, Sonos updates the electronics of their products without changing the outside appearance much. They do this for manufacturing cost reductions or tweaks and improvements. So, while one Sonos Connect might look like another Sonos Connect, they might be quite different on the inside. Sonos would not support the older version of the Connect but will support the newer version. To us though, they look the same. If you have several Connects or Connect:Amps, the easiest way to tell their vintage is to log into your Sonos account, and Sonos will tell you which of your devices are too old. It’s quite possible that many people have different vintages of equipment in their homes and don’t know it. The Connect we bought last year is quite different from the Connect we bought over 10 years ago.

The reality is that Sonos is more of a software company that sells physical music players, rather than a stereo manufacturer. The issue is that many of us Sonos customers expect to buy stereos that we can hold onto for decades like we used to with our old simple stereos. Good or bad, this isn’t the case anymore. We also want our new ‘simple stereos’ to support all of the world’s music services, voice control and whatever’s next. We have learned to not expect Microsoft to support our 10 year old PC and our TV needs to be replaced when its doesn’t have HDMI inputs, but it looks like we’re not ready for our music streaming systems to not be supported even if they’re ancient in a technology timeline.

What happens next?

The good news is that Sonos has backed away from stopping the support of quite old gear. Good for them for listening to their customers, apologizing, and trying to make things right. This is good for customer’s bank accounts and saves much gear filling landfills. The bad news is that this might slow or hobble future features that Sonos may want to introduce. First it will divert a lot of engineering resources to allow Sonos to split your old gear (no new features) and new gear (with new features) groups while still allowing them to work together in your home. Sonos will eventually have to retire these and other product though.

While we’re huge advocates for getting quality gear that can run for a long time, it’s also unreasonable to expect home tech gear to have an infinite lifespan and be maintenance free. It’s extremely hard to achieve this when home tech is evolving at an accelerated pace. We offer home tech support to keep our clients’ home tech goodness going, but manufactures likes Sonos are part of the solution.

We are torn on this one, as we understand both sides of the coin. It brings up some good questions. What is a reasonable amount of time a manufacturer should offer updates for a home tech device? And how much home tech support should these devices need? We hope Sonos can navigate it and continue to provide great products that many of love to use everyday. In the meantime, we’ll help clients with home tech support as they need it.

What’s new in mesh Wi-Fi?

The latest crop of mesh Wi-Fi products are helping a lot of people get better Wi-Fi coverage in their homes. We’re fans of using mesh Wi-Fi when you don’t have or it doesn’t make sense to run network wiring for a wired network. The new generation of mesh Wi-Fi makes it even more compelling with better stability and coverage.

Mesh Wi-Fi networks

Mesh networks are made of nodes that talk to each other to create a network. Here the mesh networks use Wi-Fi itself to bounce Wi-Fi to parts of your home. Since your Wi-Fi router is often stuck in the basement or on one side of your home, the far reaches of your place may live in the darkness of no Wi-Fi. With these nodes, you can place them where the signal is still strong enough, and it will extend it further out. You can keep installing nodes until you have the coverage you want. Consumer mesh Wi-Fi devices have apps that help you figure out if the placement is good, or if you need to find another spot.

The next generation

The last generation of mesh Wi-Fi was pretty good, and the latest generation is getting better. Their speed, stability and coverage has improved. Google has its new version, Nest Wifi, and we’ve had great success helping people with eero Pro extenders. They use three bands of Wi-Fi to help spread Wi-Fi goodness in your home. They also offer automatic software updates and network control (perhaps, for example, you’d like to pause or limit Wi-Fi for your children).

So much that we do in our homes from working to media streaming to smart home automation requires good Wi-Fi. Without good Wi-Fi, often everything becomes an effort in frustration. Mesh Wi-Fi can make the whole experience so much better – perhaps its even a great holiday gift idea!

 

Why do I need a smart home control system?

Smart home control systems are becoming more affordable and useful everyday. They allow you to simplify your world by streamlining the comfort and control of your home. But how do you know if you need a custom smart home in your home?

Replaces many remote and apps

Sometimes the trigger for a smart home control system is to simplify a TV system. You can go from many remotes to one unified remote that turns on and sets up the TV and related equipment with one press of a button. Sometimes its that you want to use one app vs. a multitude of apps to control your smart devices like your smart doorbell, smart lock or smart lights. Or maybe its both – you just want one system that you can control all your TV systems and smart devices.

Simplifies a complicated home

If you have many home tech devices in your home, then its tricky to get them to work together. For example, when you press the “Watch TV” button on your remote control, you might want it to not just turn on your TV system, but also drop the shades and dim the lights for better viewing. Maybe its a ‘Goodbye” button at your door that turns off all your smart lights, stops your music streamers and adjusts the temperature when you leave your home. You can also have device like your thermostats, lights and shades on schedules or based on sunrise and sunset to set them for you. Or check and close your garage door if its left open, or alert you there’s a water leak before you have a major issue.

A smart home control system can also bridge smart devices that aren’t inherently compatible with each other and have them play well together for your comfort and control. Increasingly homes have more and more complicated tech – these can be coordinated into one simple-to-use interface.

Provides flexibility

Life gets busy. You shouldn’t have to search around for the right remote or app to control or check on something. You should be able have control and be informed if you’re at home or far away. A smart home control system can coordinate hand-held remote controls, touch screens, and smartphone and tablet apps so you just use what’s within reach.

A professionally installed smart home control system can simplify your life. One simple-to-use system, can provide convenience and comfort so you have have more time to relax and enjoy your home.

What is Wi-Fi 6?

 

We need Wi-Fi in our homes, but the Wi-Fi people haven’t been very good at making it easy for us to understand Wi-Fi versions. Most people aren’t sure what the letters mean; is 802.11ac better than 802.11n? Now they’re trying to make it a bit more easy to understand.

802.11 a/b/g/n/ac Wave 2 – really, its not just random letters

The fundamental issue is that the non-profit Wi-Fi Alliance has been using the Institute of Electrical and Electronics Engineers (IEEE) 802.11 working group naming. While we really appreciate the Engineers work on the technology, their naming conventions are a bit hard to follow.

The Wi-Fi Alliance has finally figured this out. While we may have gotten used to names like 802.11n and 802.11ac, they decided a straight forward numbering system would be easier for non-technical people to understand. So, they have used simplified to generational names moving forward. 802.11n is called Wi-Fi 4 and 802.11ac is Wi-Fi 5. The next Wi-Fi standard, 802.11ax, is christened Wi-Fi 6. It will take a while for this to catch on, but it certainly makes it easier to understand that Wi-Fi 6 is newer and better than Wi-Fi 4. Maybe in the future, the average consumer won’t even know or need to know what the IEEE name is for a future variant of Wi-Fi.

SU-MIMO vs. MU-MIMO, what the heck are those?

While we’re waiting for the new naming to stick, the fine Wi-Fi folk have a second wave of 802.11ac (or Wi-Fi 5) coming out. 802.11ac Wave 2 has a theoretical speed of 2.34 Gbps. Of course theoretical speeds, are just theoretical, but your could be looking at about 1 Gbps when you’re in decent Wi-Fi range. In general, this means that 802.11ac Wave 2 will give you about double your network speed of Wave 1.

There’s also some fancy technology updates like improved channel use, but the other big Wi-Fi deal is MU-MIMO. MIMO, or multiple-input and multiple-output, uses multiple antennas on both side to get more out of a wireless link. Here the wireless link is a Wi-Fi connection. The MU part stands for Multi-User. Older Wi-Fi was a round-robin waiting game. You hand to wait your turn to ‘talk’ to the Wi-Fi router (ie Single-User). Of course this goes super fast, so it seems like you’re always getting a Wi-Fi turn. MU-MIMO allows for multiple users to talk at the same time – four at a time for 802.11ac Wave 2. This will be noticeable faster.

A few things about Wi-Fi 6

As you would guess, Wi-Fi 6 will be even better and faster. Its theoretical top speed is 9.6 Gbps, so even real world speeds should be impressive. It also ups the ante by being able to connect with up to eight users at a time. They’ve also worked to make Wi-Fi 6 better for low power devices like small smart home sensors, so their batteries should last longer. Wi-Fi 6 also bulks up the security to use WPA3, the next generation of Wi-Fi security.

Hopefully we’ll start seeing the terms Wi-Fi 5 and Wi-Fi 6 being used more often. While it will take a year or so until Wi-Fi 6 devices are readily available, it will help us keep track of what we should be looking for vs trying to remember that 802.11ax is better than 802.11ac!

What you need to know about 5G mobile wireless

5G is the next generation of the mobile network. As it starts rolling out this year, it will offer faster data speeds and more reliable connections for smartphones and Internet of Things (IoT) devices. Its being described as super fast, always connected mobile Internet, but that’s not quite the whole story. While theoretical data rates can be up to 10 Gbps, we’ll likely be getting 50 Mbps and up in the real world. That’s nothing to sneeze at, but we need to understand the limitations.

Really high data rates, poor coverage

One of the set of frequencies that 5G uses is very high: 28 GHz. Higher frequencies allow higher data rates. The issue is that the higher frequencies have physics to deal with. Higher frequencies don’t propagate very far, and they aren’t very good at going through walls, trees, etc. You may notice that deep in some concrete buildings, your mobile phone often doesn’t have coverage. This will be worse with the really high frequencies networks.

This means that there needs to be a lot more base stations (kind of like Wi-Fi routers, but for telecoms). Small base stations fill in coverage for today’s 4G networks in places like concrete buildings (e.g. malls, subways). Many mini base stations will be needed in a city to make a 28 GHz network work at all. We should be getting over 1 Gbps when things are set up properly – that’s pretty darn fast! Beyond being faster than home Internet, 5G is also designed to respond faster to improve network latency.

Good data rates, decent coverage

The 3.5 GHz frequency band for 5G, on the other hand, will have similar coverage to what we get today but with better data rates. This is partly due to a littler higher frequencies. It’s also due to 5G implementing better technologies like MIMO (multiple antennas working to get data to you) and beam forming (those antennas ‘pointing’ the signal to you).

While data rates will be faster than 4G, they will only be a bit faster when your smartphone connects to a mid band 5G network. Not a bad fallback when the super fast version of 5G isn’t available in the your area.

Low data rates, great coverage

The low frequencies bands are really good for their inherent coverage. While the data rates will be slower, the lower frequency band, 600 MHz, can travel farther. It isn’t bothered as much by pesky buildings, trees, etc. While perhaps not very useful for a high data user (e.g. someone watching Game of Thrones at 4K on a bus), it will be incredibly useful to little devices and sensors scattered around our world sipping on data. These IoT devices could be handy for home tech, but also for commercial and industrial needs.

5G might not be the perfect, super fast mobile network some describe it as, but it will offer a significant step forward. 5G can also be used as a short cut to a fast Internet connection for rural households without wires or fibre. It may also kick off some really useful IoT innovations.

For coverage and high data rates, we may need mobile network boosters in our homes. Otherwise we’ll need smartphones that switch over to Wi-Fi networks better. (It’s quite possible that you may already need a booster in your home to get coverage for our current 4G network.) In the end, 5G may leave us wondering how we lived without out it.

Convenience vs. smart device privacy

There’s no denying the conveniences that technology provides in our lives. There’s streaming services, social networking, voice assistants, and smart devices that are truly great. All of this often comes at low dollar cost or sometimes even for free. There are trade offs of smart device privacy that you should be aware of though.

What’s the real cost?

This often comes down to how companies make their money. Do they make their money from selling devices or services directly to you, or are they basically (or totally) giving it away and making money from data tracking for advertising or selling info about you? Or maybe its a combination of these.

Vizio stormed into the TV market by selling TVs at very low prices. It surfaced that they accomplished this in part by selling people’s viewing data to other businesses. Its well known that Google and Facebook make money by ads layered into their free services. While Google looks to be trying to fix privacy issues, Facebook keeps getting their hands slapped for their cavalier use of data including detailed user data that was shared with their ‘partners’. Recently we learned that Amazon provides employees with scripts of users interactions with their Alexa voice assistant. While this makes sense to improve the service, we don’t know how securely they treat these scripts.

What can you do?

You should educate yourself on what the privacy cost is for your favourite tech. Then it’s up to you if you want to take advantage of devices or services without paying the real monetary cost of these. By carrying around a smartphone, we’re giving usage data to the smartphone manufacture and our mobile carrier. Often we’re happy to make this trade off for the features and convenience of smartphones. Apple is making a push to point out their privacy policy. Great, but you should read it and make sure it aligns with your privacy goals.

You can also turn off certain features. For example, you can turn off Apple’s Siri voice assistant from always listening (but then you can’t just say, “Siri…” when you want help). Similarly, you can set Alexa to not always listen and instead require pushing a button to get Amazon’s voice assistant on their devices. Of course, disabling these make voice assistants less useful.

You can also use a tool to track them track you. For example, Princeton has created a tool to track smart devices in your home. Its a worthwhile exercise if you have concerns.

Are they keeping your data safe?

Unfortunately even with your best research, you may not know that some companies aren’t up to speed yet. Even a giant like Facebook (yes, yet again) recently admitted to having a bunch of user passwords in plain text – readable by anyone in the company (or a hacker) and not digitally scrambled. The good news is that reputable companies are stepping up. Also governments are starting to provide privacy requirements like GDPR to help keep their citizens digitally safe. (Hopefully Facebook will finally get the memo after so many missteps!)

These’s no blanket right or wrong answer for everyone

Smart device privacy might be the top priority for some. For others, they’re happy to give away personal or aggregate information to get great services on the cheap. Just remember that you’re paying one way or the other. With some research or getting help from an expert, you can find your balance of tech nirvana and privacy.

Sonos streaming music architectural speakers

Sonos has been pretty busy of late. They’re bolstering their streaming music portfolio with additional products. Last year, they released a more affordable TV sound bar, and recently they updated with their Amp. Now, they have announced branded architectural speakers.

Sonos architectural speakers

Sonos is already great when used with architectural speakers. People get great sounding streaming music, and the speakers don’t visually impact a room. Architectural speakers are passive speakers (they need a separate amplifier) that are installed in ceilings and walls, so there is no need to have regular bookshelf or floor standing speakers in the room. This is great not only for current modern home aesthetics, but they also save valuable floor space. Sonos has announced three speakers: in-ceiling, in-wall and outdoor speakers. Sonos partnered with Sonance, a respectable speaker brand, for these speakers. These ‘matched’ speakers make it easier for consumers to understand and select architectural speakers if they’re the DIY types. The Amp also enables Sonos’s Trueplay which allows for easy speaker sound optimization. Other speaker brands will continue to sound great with the Sonos Amp, but these will help make architectural speakers more mainstream.

Sonos has more to come

Sonos recently also showed off some product prototypes that they have partnered wth Ikea for. The intent is to make Sonos compatible speakers more affordable and widely available. Sonos also quietly stoped selling their Play:3 speaker, so we suspect an updated version may be on the horizon. While we’re fans of Sonos, they’re not the only great streaming music solution out there. These recent updates are great as it pushes all brands forward and provides more great streaming music options available for consumers.

The new Sonos Amp

Sonos is replacing the Connect:Amp with their Sonos Amp. Unlike their standalone speakers such as the Sonos One, the Sonos Amp can be connected to stereo speakers or other speakers. For example, we often use it with in-ceiling speakers in homes. Its currently available to integrator people like us, and will be available to Canadian shoppers in February. The new Sonos Amp has most of the same connection options as the Connect:Amp (speaker connectors, left/right inputs, sub output, two Ethenet ports). It also adds an HDMI connector for TV connections. Overall it looks like a nice update – let’s take a closer look at its main features. 

Power output

The feature that most people will notice is that they’ve bumped up the power to 125W on each side from the Connect:Amp’s 55W. While most people don’t need the volume from the extra power, it should help improve the sound even at lower levels when parts of music need more oomph. This will be particularly handy if you’re using it with four speakers, such as four in-ceiling speakers.

TV friendly 

We think the Amp is most likely to find its spot hidden away in a technology closet in a home, but it can happily be placed in a living room. If you want to use it with your TV, it has a HDMI connector for TVs with an HDMI ARC output. You can start with just your stereo speakers (it emulates a centre channel). You can then add other Sonos speakers for surround sound. It also has an IR sensor so you can use your remote control for the volume.

Future features

We suspect some of the Amp’s best feature’s are yet to come. Since it’s a new platform, there are features that can be added in the future. For example, it’s compatible with Apple’s AirPlay 2 unlike the Connect:Amp. We look forward to the possibility of native support for other smart devices such as smart doorbells. 

While many see the Sonos Amp as an ‘integrator’ focused device, it should slot in with the same kind of people who are using a Connect:Amp with their stereo speakers. We’re currently testing ours with our turntable setup, and so far, so great! We look forward to using it in our clients homes to harness the increased output power and future technology options.

Understanding home control technologies


All of your tech gear, from TVs to smart home devices, needs to be communicated with to do the great things they do. Not too long ago, you could do this with a basic remote control. If you wanted to simplify your system, you got a (sometimes not-so-simple) universal remote that was able to control your TV, VCR (remember those?) and sound system. These days, there is a plethora of ways to communicate with everything from TV to smart home products. Here’s a crash course on the more common home control technologies that are used these days.

The difference between one-way and two-way home control technologies

There are two basic categories of device control: one-way and two-way. As it sounds, one-way controllers only talk one-way – they don’t listen to check if they were heard or understood. An old school TV remote is a one-way device. You point it at your TV and press a button, like a channel button. If you pointed the remote mostly towards the TV and all worked well, the channel would change. The remote has no idea if anything changed. That’s up to you – if it didn’t, then you need to press the button again.

Two-way controllers both talk and listen. You can use two-way devices to have a ‘conversation’ and confirm that the task was completed. The device can even send back information like what its volume currently is. 

One-way home control technologies

The more common one-way home control technologies used are IR and RF. IR, or infrared, is light that we can’t see. It is used to carry control signals. Since its light, devices need to ‘see’ their remote to work. Otherwise its pretty robust and is used for devices like TVs, sound systems and cable boxes. RF, or radio frequency, controls put the control information on radio waves. These are similar to IR, but with the added benefit that radio waves can travel through walls and cabinet doors, etc.

When one-way technologies fail, like in the channel change example above, you have to correct for it manually. For a simple system, like a TV and cable box, this usually suffices. (Not always, though: the elderly lady down the street often gets stuck in a cycle where her cable box is on while her TV is off, and vice versa.) For more complicated systems with many devices, you need to make sure that all the devices got their messages. Otherwise, results can and do vary. This is where two-way systems can overcome issues and ensure home tech bliss.

Two-way home control technology

Two-way home control technologies provide a much more stable interface since the controller can get a response from the device to ensure all is good. Common two-way technologies include RS-232, IP (Internet Protocol – wired or Wi-Fi), Z-Wave, ZigBee and Bluetooth. Note that Wi-Fi, Z-Wave, Zigbee and Bluetooth are all wireless technologies. These can work fine as long as devices are within the specified distances, etc. RS-232 and wired IP are usually preferred, as you don’t have to be concerned with wireless coverage issues. But, of course, you do need wires. 

Interestingly, RS-232 is actually a very old computer communications standard (from the 1960s!), but its still very capable and usually preferred by home technology professionals to control devices. The reason is that controlling devices doesn’t require much data or fast speeds, so the ol’ reliable RS-232 can still keep up with our latest technology. Its usually preferred even over wired IP, as then control doesn’t have to compete with other data, such as streaming Netflix video. That said, the ubiquity and consumer friendliness of IP makes it the go to for modern smart home systems. Obviously with a wireless control technology though, you don’t need to run wires around your home. 

The smart home system you choose often dictates the home control technology. Often people don’t consider the future headaches when choosing a certain technology for the wrong situation. Its not a coincidence that long term stable systems use a wired two-way control technology, especially old, boring RS-232. A good control system, like from RTI, will work with many or all of the home control technologies, so you can mix stable products with convenient wireless ones where the scenario makes sense. Either way, when implemented properly, you can harness their technologies to make a very complicated system a snap to use.
