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?
Be careful with zooz if it's for a fan (even a small exhaust fan). Their specifications don't support that type of load. They do have some dry contact type switches that can handle fans, though. Not to mention it's Zwave. Nothing wrong with Zwave, but you'd also need a hub.
Look into Shelly. They sell things that get stuffed in with your current switch. They have UL certified options, even. They work over WiFi and there's a built in HA integration.
Shelly is good but one of my switches overheats constantly. Shelly 1 Plus PM.
That sounds like it’s a fire hazard, and could be caused by bad wiring, not necessarily the Shelly device itself.
Definitely could be.
I've seen lots of reports of them overheating in crowded boxes. I recently removed it just in case I botched the set up.
