You need a decora style outlet and switches. They all have the same large rectangular opening. All the Caseta wireless switches use that style. Not sure on open source options.
Also make sure that outlet is GFCI while you’re at it.
You know... I hadn't even noticed that outlet wasn't GFCI... Ha!
Ok, you (and everyone else in thread) are right, the idea of rewiring the whole box wasn't appealing to me, but if I'm being objective it's actually not that much work and is probably less money overall than the smart switch itself.
Thanks folks, for shaking the blinders off me!
It could be down the line from another GFCI receptacle and still be protected. You can use a tester to trip it and see.
This right here is the answer. The fact that you have an outlet means you also have a neutral. That guarantees that you can use literally any Smart Switch you want.
Just replace the outlet with a decora style outlet, install two Smart switches, and put a three gang decora wall plate on. And you're done.
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.
