TP-Link Tapo Smart Light Switch 1 Gang 1 £15.99 @ Amazon

In most situations, forget the single switches imo - this system really benefits from using double switches & using the second switch to control another device.
This might be another light switch or a tapo smart plug.
E.g. replace a standard single switch with a double smart switch, have the first switch control the light as usual & the new second switch to control whatever makes most sense to the location - it's basically a free switch to another light already attached to a smart switch or plug.
It's great where you only have one switch point for a light & smart buttons can be used to provide a second switch wherever you'd want one. Smart buttons can also control tapo smart plugs.

I have three of these and they are great! Yea you need a hub and they take triple A batteries but they are so simple to install and set up it doesn’t bother me at all. I just wish they had a solution for two way switches and I’d fill the whole house with them.
