I am addressing this topic here in order to find out wether also others have similar problems with Zigbee control elements made by Busch-Jaeger:
I do have about 12 Zigbee Light Link control elements (product description) installed. In general this provides a great integration of Philips Hue compatible lights in replacement of “old” wall switches as well as integration of “traditional” lights for home automation.
While in most cases the system works fine, the Busch-Jaeger Zigbee control elements sometimes simply stop operating. Then they need to be pulled from the insert and pushed in back again in order to work normally again.This happens appr. all 3-6 weeks with one to two elements.
I am in contact with Busch-Jaeger since December last year. I also sent them one of my control elements so that they could test it in their environment. Even after several months they are not able to reproduce the problem.
To me it seems to be related to the management of the Zigbee Mesh-Network Management. Whenever another Hue controlled item fails, the failure of one of the control elements seems to be more likely.
Is there any one else having these kind of problems? It would be great to know and give Busch-Jaeger some more evidence on this issue.
