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?
As others mentioned, you can probably use a 3 gang standard faceplate.
The other option would be using a Shelly this is wired like a 3-way switch inside the box; the outside will look normal. As long as you have space, I think the mini should work but I'm not super familiar with their models.
