Shelly Wave 1 Mini

Tucked this behind my bathroom light switch to control the exhaust fan, and the dry contacts were exactly what I needed since the fan has its own power feed. At 8 amps it handles the load without getting warm, and it's honestly tiny enough that I forgot it was even there. Pairing took a couple tries

Fits behind my existing wall switch with room to spare, which I honestly didn't expect from a Z-Wave relay this small. The dry contacts let me wire it to my garage door opener instead of a light, and it's been rock solid for a month.

I wired this behind an outlet to control a lamp that was always left on, and the dry contacts made it dead simple. At 8 A it handles the load without getting warm, and it's genuinely tiny — barely took any room in the box.
