Wondering what light switches work very well with Home Assistant, specifically two switches or three switches in a 1-gang (US/Canada) wiring box, or a 4-switches in 2-gang format. (Sorry, UK and other non-North America)
Bonus marks for local-polling, API, and physically water-resistant (bathroom install) 
This seems like Tasmota, maybe 2x T1-2ch can fit side-by-side in a 2-gang box? Does the glass front overhang? Or is there a better solution?
