I have a Smartthings system on a V2 hub with 50+ (hardware) devices, including about 40 ZWave switches and outlets. Over the past 3 years, 10-12 GE switches and 3-5 GE outlets have failed and had to be replaced. As near as I can tell, all the devices stopped working when the relay failed (blue light flashing - resetting doesn’t help).
The problem is bad enough that I now keep an inventory of replacements on the shelf.
What’s particularly frustrating is that they seem to be particularly prone to failure right when I turn a circuit back on after replacing a failed switch. It happened today. I cut the power and replaced a failed GE switch in a bank of three with an iNovelli unit. As soon as I reset the circuit breaker, an adjacent GE switch failed. I gave up and replaced the second failed one and the third one (which hadn’t failed) just so that I wouldn’t have to come back to it.
I have begun to replace the GE switches with iNovelli switches (8 so far), hoping that the reliability will be better. I haven’t had the iNovelli ones long enough to tell if they will last longer yet, but I do like the firmware better and the setup is much easier.
Unfortunately, there are no iNovelli outlets, so for now I am stuck with the unreliable GE Enbrighten ones. I replaced one of those today.
Anyone have similar problems? Ideas?
