7.2 Duty cycle
The duty cycle is a legally regulated limit of the transmis-
sion 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 processes mean that it may be reached in isolated in-
stances during start-up or initial installation of a system.
If the duty cycle is exceeded, this is indicated by one long
red lighting of the device LED, and may manifest itself in
the device temporarily working incorrectly. The device
starts working correctly again after a short period (max.
1 hour).
