I’m not really sure if this should be in hardware but it feels more like a “Share” to me.
Posted this in r/homeassistant yesterday also.
So I found this great button that can be wired for normally open or normally closed.
I wired it into an open/close sensor to activate my Christmas lights.
Mounted on a cigar box. Really fun.
The lights are on a schedule now but wanted something fun for the kiddos on the first night.
