Troubleshooting
6.1
Command not confirmed
If at least one receiver does not confirm a command,
this may be caused by radio interference (see „9 Gen-
eral information about radio operation" on page 12).
The error will be displayed in the app and may be cause
by the follow:
•
Receiver cannot be reached
•
Receiver is unable to execute the command
(load failure, mechanical blockade, etc.)
•
Receiver is defective
6.2
Duty cycle
The duty cycle is a legally regulated limit of the trans-
mission time of devices 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 teach-in pro-
cesses mean that it may be reached in isolated instanc-
es during start-up or initial installation of a system. If
the duty cycle limit is exceeded, the device may stop
working for a brief period. The device starts working
correctly again after a short period (max. 1 hour).
