I just use a Sonoff switch for lights, fans, all sorts.I've been looking for a wireless smart switch to control a bulb. Reason being when coming home at night, there is no light switch next to the door but about 2 meters away.
The only thing I have come across is the Luton Caseta https://www.amazon.co.uk/Lutron-PJ2-3BRL-WH-L01R-Control-Favorite-Setting/dp/B00KLAXFQ0/
I'm assuming it can pair with any bulb? Does anyone have this or is there even an alternative?
