I am fairly new to home automation and I am looking to add a few physical wall switches to devices that don't have a specific wall switch of their own. I have a couple rooms where I want to put a light on a smart bulb/plug/relay but want to be able to turn the light on/off via a physical interaction at the door, like a normal light switch.
The only solution I see right now is to expand the hole for the existing light (ceiling fan actually) switch, add another smart switch that doesn't actually have a load, and then set it up so if that switch is turned "on/off" then I have a automation that triggers the smart relay.
But that seems like gross overkill. I honestly don't care about cutting holes or wiring stuff up, but somehow paying full price for a smart switch and then using it as nothing more than an alternative user interface for yet another smart device seems really wrong.
Currently I have several kaso/tapo switches installed and have been looking at some smart relays/plugs/bulbs to turn on a lamp, or trigger the light on the fan separately from the fan itself.
