Hi all,
I am in the process of making all my "dumb" switches "smart".
So far I have managed to make the 1 way switches work perfectly. However my luck ran out when I tried the 2 way / hotelswitch variant.
I folowed the folowing schema
I am using momentary switches and changed the button type to momentary. When I combine the cables going to the SW port of the shelly using a WAGO welding clamp, neither of the switches will turn on the light. When I connect them individually they work fine.
Does anyone know what I am missing here? This is driving me nuts.
