Aqara Light Switch Bracket

I needed to add smart switches into my home to use with my smart bulbs.
I needed more than a basic on/off toggle but didn't want to rewire the house to have neutral wires in the back of the switch.

It works fine with plastic switches, the magnets are aligned with the switch mounting screws
