I’ve installed HomeSeer HS-WD100+ and HS-WS100+ switches in my house. They work perfectly for the most part. In my master bedroom I also have a GE Fan controller switch (12730) - I chose this to match the other switches, and I suppose you can’t use a HS-WD100+ for the fan, even though the GE seems to work identically.
In the master bedroom the fan light and lamp pulse for 10-15 seconds every 60 seconds or so. I have double checked my neutral connections to make sure they were secure. I bought a multimeter and observed that while the pulsing occurs the voltage alternates between 120 and 117.
I have a Keurig plugged in on the same circuit, and curiously it doesn’t happen when I have that unplugged, but the alternation in voltage still happens, just at 121 and 119/120. On every other circuit the voltage stays constant.
Since the alternation happens on every plug on the circuit, I ruled out a wiring issue with the Z-Wave switches themselves. Those are at the end of the circuit. And I have verified every plug is wired correctly.
I had a retired electrician come over (a friend) and he found what he thought was a CGCI breaker on the bedroom, which he thought was odd. After doing some of my own research, I’m fairly certain they are actually AFCI breakers, which are required in bedrooms starting 2014.
So it seems like the wiring is correct and the breakers are correct. So I’m left with three possibilities:
1 - The HomeSeer switches are not compatible with AFCI.
2 - The GE switch is not compatible with AFCI.
3 - The Cree LED bulbs (dimmable, newer model I believe) are not compatible with AFCI.
W/ the first 2 I’ve read that Lutron had some sort of filter for their dimmers.
The guest bedrooms share an AFCI breaker (I use one as an office), and I’ve observed the lights slightly dim when I turn the computer on.
I don’t have any of these issues on the other circuits which have standard breakers.
So far I’ve thought of disconnecting the GE fan controller and see if that makes a difference. The HomeSeer dimmer. And last (or first?) try a different brand of LED bulb (Phillips?).
Does anyone have any other suggestions?
