Hello folks! I have these switches in my bathroom.
The rightmost is the lights, and the middle one is the bathroom fan, and I'd like to replace that middle one with something I could load tasmota on (or some other open source firmware), without replacing the other switch, the sockets, or the faceplate.
I haven't seen any smart switches that have a form factor that would fit through this faceplate, though; they seem to mostly want to be the entire electrical box.
If it weren't for the electrical plugs I could maybe replace this with some kind of 2-gang thing, which isn't really what I want but could be fine, but as it stands I'm not sure what my options here are.
I don't need the new switch to necessarily look like the old one, I just want it to fit in the same box and use the same faceplate. Do you folks have any recommendations?
I’ve seen this one which may fit what you’re looking for. No idea about open source firmware though.
This one might work for you too.
Really though, if you’re already spending money on a smart switch, you should probably just replace the outlet, other switch, and faceplate with decora (rectangle style) versions while you’re at it. It’s only going to run about $10 total for all those. Plus you can then use a smart switch that meets your firmware needs.
