I have been on a mission to find the ideal light switch for my smart home. I don’t have an answer yet, but am working through a number of options, using the ever enjoyable Paul Hibbert advice along the way.
I am on the hunt for a in wall physical switch to replace my existing ones that has the following characteristics:
- Physical buttons so it looks like a normal switch
- Ability to decouple the switch from the load so I can put in smart bulbs and use the switch to trigger it from Home Assistant
- No neutral required (we don’t have a neutral wire behind the switch in a UK wiring setup)
- Ideally Zigbee but I have been looking at Tasmota compatibile options
I can find switches, such as Tuya Wall Switches, that will do everything I need but they require a neutral wire to power the electronics in the switch. There are ways around this by putting a capacity across the bulb to allow it to keep powering the switch even when the bulb is off but I have found these to be very noisy and buzz a lot.
One solution is to close the circuit in the wallbox with a coupler and then just have a wireless button stuck on top but this feels a bit wrong.
My next attempt in an in-wall zigbee switch that will sit behind a normal switch - shall let you know the result!
