Anyone know of anything I can diy or buy that can flip my fan switch that can connect to HA through wifi?
It's a standard us switch, so a flip switch.
I don't want to replace the switch, because it's a dual switch and the lights on the other switch are smart bulbs.
I have a 3d printer if that helps, and I can solder.
I also don't want it to cost more than 20-30 dollars, as always, cheaper is better.
