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 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).
