Shelly
1 Mini Gen4
A compact Gen4 relay module with a potential-free (dry) contact output for switching lights, appliances, or low-voltage circuits in tight spaces. Multiprotocol radios let it run on Wi-Fi, Bluetooth, Zigbee, or Matter to fit almost any installer's ecosystem.
Works on integrations
Protocols
One mode at a time: the device serves one of these combinations, not all of them at once.
Setup guides
Roles it can fill
Native Shelly integration, local, no cloud required (also MQTT, or Zigbee via ZHA/Zigbee2MQTT, or Matter over Wi-Fi). Single potential-free (dry) NO contact rated up to 8A; no power metering; an internal temperature sensor protects the relay.
