Shelly 1 Mini Gen4 relay controller with Zigbee and Matter
Delivery options to:
Choose countryThe Shelly 1 Mini Gen4 is a compact relay controller for lighting, gates, bells and automation circuits. Its potential-free contact provides galvanic isolation of the controlled circuit, while the 29 x 34 x 16 mm housing fits installation boxes, including behind sockets.
Connectivity and automation
Wi-Fi, Zigbee, Bluetooth 5.0 and Matter support offer several integration options, including Google Home, Alexa and Samsung SmartThings. The controller also acts as a BLE gateway and a Wi-Fi and Zigbee signal booster.
- Automation: up to 20 schedules, scenes and scripts. Configure schedules and scenes in Shelly Smart Control.
- Local or remote access: control without cloud access or over the internet, with a built-in web interface for browser-based configuration.
- Integration interfaces: HTTP/HTTPS, MQTT, WebHooks and KNX net/IP APIs.
Supply and load connections
The controller requires a 110–240 V AC power supply. Relay switching limits are 240 V AC at 8 A or 30 V DC at 5 A. Support for switching a DC circuit does not mean the controller can be powered by DC.
External protection is required with a B or C tripping characteristic, rated current no higher than 10 A, breaking capacity of at least 6 kA and energy limitation class 3. There is no built-in overvoltage, overcurrent or over-power protection.

Can the controller work without cloud access?
Yes. It supports local control without cloud access, and its built-in web interface allows configuration through a browser.
Can I power the controller with 30 V DC?
No. The specified controller supply is 110–240 V AC. The 30 V DC rating refers to the maximum voltage of the circuit switched by the relay, not the device power supply.
