Description
The SONOFF MINI ONE (MINI-1GS) is a compact Matter over Wi-Fi smart switch from the SONOFF MINI Extreme Series Gen5. Rated at 16A with a 3840W maximum resistive load, it can handle high-power loads such as storage water heaters and electric underfloor heating.
It works with Matter ecosystems including Apple Home, Amazon Alexa, Google Home, SmartThings and Home Assistant. You can also control it from a local web page in your browser with no app or cloud connection, or integrate it through its open API over HTTP (JSON-RPC 2.0), WebSocket and MQTT. It installs behind your existing wall switch, so you keep both manual and smart control.
Note: a neutral wire is required. Installation in a wall box with 60 mm depth is recommended.
