The Somfy One+ has an internal battery that provides 6 hours of battery life in the event of a power failure.
That is why we recommend ensuring that your Somfy One+ is always plugged into a power outlet, preferably by a direct connection rather than through a power strip.
If a power outage occurs, you will receive a notification on your smartphone when the electricity has been restored.
Also, if the Internet connection is lost, the Somfy One+ automatically records all events to its internal memory. If you have a continuous recording service, the recording is transferred to the servers once the connection has been restored.
