What can I do if I do not remember my system security key and the Homematic devices are not connected to the Homematic Central Control Unit anymore?
It is not possible to directly restore the factory settings of the device as described in the corresponding user manual.

Some of our partners offer a special service for such cases. Please directly contact your supplier for finding an appropriate solution.
