I recently purchased a number of Honeywell Z-Wave Plus In-Wall Smart Switches (model: 44946) and have already installed 8 of them and they work beautifully. I have a few 3 way switches in my home and when I tried to purchase Add-On Switch (paddle version) for the Honeywell 44946 they are sold out everywhere! Does anyone know if a GE Add-On Switch will work with Honeywell 44946.
Another option is to buy GE Z-Wave Plus Switches for my 3-ways since the GE Add-On switches (paddle version) are freely available, however I am not sure if the LED color on the GE Switches is the same as Honeywell Switches. My Honeywell Switches have a blue LED.
Every GE switch/dimmer/fan controller I have has a blue LED also. One of the main reasons I went with them was that and they match the cheap Leviton Decora standard switches well enough to blend in.
Thanks @HalD, I was concerned if they might different signaling despite the shared Jasco manufacturing – your hunch was correct – I called Jasco and I was told that a GE Add-On should work just fine with a Honeywell switch.
