Wouldn't it be nice to come home, and have your home react to your arrival by turning on some lights, setting the air temperature to how you like it, and perhaps letting your other family members know you have arrived (even if they are not at home themselves)? Home automation has been the domain of DIY'ers or expensive commercial contractors for decades. That era is rapidly drawing to a close. Today, there are numerous entry level kits that allow just about anyone, whether they have 'techie' skills or not, the ability to jump in. There are so many options now, that it is often difficult to choose among the various brands. The big box home improvement stores are dedicating end-caps to their brand or versions that they are backing.
Among the better known brands:
Lowes Home Improvement stores are putting their weight behind a system called Iris Smart Home Management System. It can be purchased as a kit, or each part or component can be purchased individually. Iris is the Lowes brand of home automation, and it can only be purchased through their stores. Their systems start below $200 for the basics, and can be expanded out to a full blown security system, or as simple as turning lights on and off. Any Iris labeled product is pretty much assured to work with the system.
Home Depot doesn't have it's own private label, but does represent the Wink and Quirky/GE products. This system is built around the Wink app for Android or iOS devices, which can interface with many individual products by itself, or with many more if you also purchase the Wink Hub. This system is less a product line than a series of products that all work together through the apps inter-operability. As with the other automation solutions, it is scaleable from small to pretty much full scale. Wink uses a variety of protocols, and there are many products that are labelled "Wink Compatible", even to the level of detail of whether the hub is required or not.
Insteon is not linked to a big box store, but has a very thorough product set that can start as simple as an app and a device, and work up to a complete comprehensive system. The entry point is a little pricier, but it does have a mature product line that could easily be called complete.
X10 is kind of the grandfather of DIY home automation. It has been around for longer than most, and has a fairly complete set of products. One unique difference of the x10 line is the wide variety of off the shelf remote control devices that are X10 compatible, even those that also have universal remote control features for home audio systems.
Vera positions itself in the market as a competitor to the monthly subscription model of home automation offered by cable or alarm companies. It too, has a robust product set that one would be hard pressed to find incomplete. It is scaleable, affordable, and has been around long enough to assure stability.
After weighing the pros and cons of these systems, I decided to start experimenting with Wink. I liked that it was multi-protocol; it works with Z-wave, ZigBee, Bluetooth, and Wifi. The hub was low cost, available for $50 or less. To me, the main appeal was that it seemed much more open architecture than the others, and with multiple protocols, it was open to a wider set of options. I don't mind getting down into the code or into detailed configuration scripts, in fact, I enjoy it; but I also wanted to see how simple this could be, so this was a factor as well. I purchased my Wink Hub from Amazon, for less than $50, including free second day shipping.
