Troubleshooting
•
Your device will automatically appear in the Homematic IP app.
•
To confirm, enter the last four digits of the device number
(SGTIN) in your app or scan the QR code. The device number can
be found on the sticker supplied or attached to the device.
•
Wait until pairing is completed.
•
If connecting was successful, the LED (A) lights up green. The
device is now ready for use.
•
If the LED lights up red, please try again.
•
Select the desired solution for your device.
•
In the app, give the device a name and allocate it to a room.

Troubleshooting
7.1
Command not confirmed
If at least one receiver does not confirm a command, the device LED
(A) lights up red at the end of the failed transmission process. The failed
transmission may be caused by radio interference (see see „10 General
information about radio operation" on page 41). This may be caused
by the following:
•
Receiver cannot be reached.
•
Receiver is unable to execute the command (load failure, me-
chanical blockade, etc.).
•
Receiver is faulty.
7.2
Duty cycle
The duty cycle is a legally regulated limit of the transmission time of de-
vices in the 868 MHz range. The aim of this regulation is to safeguard the
operation of all devices working in the 868 MHz range.
In the 868 MHz frequency range we use, the maximum transmission time
of any device is 1% of an hour (i.e. 36 seconds in an hour). Devices must
cease transmission when they reach the 1% limit until this time restriction
comes to an end. Homematic IP devices are designed and produced with
100% conformity to this regulation. During normal operation, the duty
cycle is not usually reached. However, repeated and radio-intensive pair-
ing processes mean that it may be reached in isolated instances during
