The Sonoff Mini Xtreme is compatible with the EWelink app and can be easily integrated into both Google Home and Alexa, making it perfect for home automation. Its small dimensions allow it to be placed in classic 503 boxes or in two standard Italian sizes, making it very versatile. It is important to know that it requires dual power supply: if the system has only one wire it cannot be used. For practicality, it is recommended to install in an electrical panel, so in case of router replacement, reconfiguration of all devices will be simpler and faster, avoiding the need to open individual boxes.
However, as long as the router remains the same, the connection is stable and reliable.

Really small, you will need a mini-screwdriver to connect the N and L cables. Fits in a box with a diameter of 8 cm. Easy to install. With the presence sensors, the Zigbee bridge, and this MiniR4 relay, the mechanical ventilation only activates when you enter the bathrooms. Much more economical than hiring a specialist and running cables…
The installation is so simple that anyone with a basic understanding of electricity can do it.
