I'm looking for a single or dual Wi-Fi light switch that I can activate with Linux. It needs to fit a standard 2-gang switch box and/or include a trim plate that covers a 2-gang box. Anyone know of such a thing? I can't tell from the selection on Amazon if any of these work without installing some smartphone app. I'm based in the US.
At this point, I'd settle for a micro-remote controlled switch, if nothing else, and then just wire a Raspberry Pi to the contacts.
The current switches I have in the gang box now are like this one. I suppose there is a little room for a wider switch – like I just found a Z-Wave switch , but they don't list with dimensions of the switch so I don't know it will fit in the box next to the "regular" switch.
