Nice and easy to install. Work well, added to the app pretty easily.
The switch allows automation through the app or home assistant and manual mode via the existing switch
As advertised
Once it’s up and running, it’s bullet proof, but with a caveat.
I wanted to use 4mm wire to match the 16a rating of the switch, but the connectors on this device are absolutely tiny and they basically don’t fit.
I’d recommend using 2.5mm - it will handle 16a, and will more easily fit the Shelly.
