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?

In addition, this Leviton ZigBee switch does 15A and it works with HA Yellow. It's got your standard NA certifications and you know, it's Leviton.

Another option would be to rework the box/plate to a 2-gang or a 3-gang with one blind; short the fan leads to supply current at all times; put a smart plug in-between the fan and the power line. My bathroom fan has a small outlet that it connects to so I stuck a Hue switch directly in-between and removed the switch from the wall and replaced the plate with a 2-gang with a single opening. I also have a booster fan that was hardwired. I spilt the wiring, terminated it in a 1-gang box with an outlet. Terminated the fan cable with a plug. Added a smart plug in-between.
