My wife just got me a Smartthings Hub for christmas and I have been going wild with some of the things you can do with this setup.
I just dove into getting some switches for my 3 tube 3" florescent kitchen light and my dimmable kitchen table light.
I got a GE Z-Wave Plus Wireless Smart Lighting Control Smart Toggle Switch 14292 for the large fluorescent light and an innovelli Z-Wave Dimmer Switch + Repeater for my table light.
First of all both are installed the same way, and both take up similar space in the gang box in the wall.
As far as instructions, innovelli made it SUPER easy with their included instructions - I was absolutely impressed with the level of detail they included to make sure I knew exactly how to install the device. The GE switch was frankly lacking for someone who is very new to this type of technology (I am a network engineer by trade).
The GE switch, however, after about 24 hours locked up and would not respond to commands. It wouldnt even work when using the physical switch!
I tried to reset my hub, no luck. I tried to reset the device, however, there is no physical way on that model to reset the device and the instructions were not clear on how to do it either. It mentioned a completely different model (the paddle switch model, rather than the toggle switch). I had to flip my breaker, put the device into exclusion mode, remove the device from smartthings, then re add it to get it to respond again. In all it was about 2 hours of troubleshooting a light that was stuck ON.
The innovelli device has worked flawlessly, and it was a similar cost to the GE switch. I see that Innovelli is a fairly new company, but they seem to make a quality product. It feels as if it’s a better build than the GE switch too. I am looking forward to more of their stuff that is coming out in March of 2018.
