If the LED on the charging station of your SILENO free flashes blue, this may be related to the docking point.
The LED on the charging station flashes blue until a docking point has been set for the device.
We recommend checking this by opening the smart app and setting a docking point for the device (again) or changing it once. To do this, follow the instructions in the smart app.
Also note that the docking point is only set, once the device has successfully approached the docking point.
After these measures, the LED should (again) switch to a permanent green light.
