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 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
instances during start-up or initial installation of a
system. If the duty cycle is exceeded, this is indicated
by one long and one short red flash 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).
