Only wireless wall switches for entire house

The first thing to do is double check with an electrician who knows the code being used where this build is being done… I’m not sure about current code, but previous NEC versions required all habitable rooms, kitchens, and bathrooms to have at least one wall-switch-controlled lighting outlet (or wall-switch-controlled receptacle in bedrooms)… and those wall mounted switches could not be completely dependent on batteries.

In my experience Tuya’s Zigbee devices can be very hit-or-miss. I haven’t kept detailed stats, but I would estimate, conservatively, that 1 in 4 battery-powered devices and 1 in 6 mains-powered devices just will not stay connected to the mesh reliably. If you decide to go that road, purchase at least 50% more devices than you need.

Also, you should make sure you have at least 2 Zigbee router devices per room.
