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 sec-
onds 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 de-
signed and produced with 100% con-
formity to this regulation.
During normal operation, the duty
cycle is not usually reached. However,
repeated and radio-intensive pairing
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 three slow flashes 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).
