I carried out firmware updater from 1.4 to version 1.6 at the gateway. The gateway no longer functions after the update. The four sensors are in the device list but not in the overview. Basic data for SMS Stick had to be re-entered. Gateway can be addressed remotely, but the sensors have no function. I completely deleted the motion detector, performed a reset and redefined it as a device. Even now, the sensors and the gateway do not function.
