Shelly Wave Pro 1

Wired this into the breaker box to switch a hallway light circuit and it fit the DIN rail perfectly. The dry contacts meant I could pair it with my existing setup without any rewiring drama, and it's been rock solid for a month.

Fits right onto the DIN rail in my breaker box and the dry contacts were exactly what I needed to trigger my garage door. Pairing it with my Z-Wave hub took a couple of tries, but once it caught the signal it's been rock solid for weeks.

Installed this on the DIN rail to control my garage heater through Z-Wave, and the dry contacts were exactly what I needed since there's no separate relay to wire in. Only gripe is the manual is a bit thin on pairing steps, but once it connected the thing has been rock solid.
