I recently started to explore HA to steer and visualize my wired KNX bus at home. I currently run it in parallel to my BJ Controltouch server which runs without issues since 2017. I have a HA green server.
I was initially very enthusiastic about HA and its capabilities. But now there is an issue that drives me crazy. I read about similar issues with Zigbee lights and adaptive lightning but in my case its with 2 different (wired) decentral LED controllers. There are 2 dimmable lights (one in the kitchen and one in the living room) that get switched on in an hourly cadence. I can turn them off manually and they get turned on again a couple of minutes later (e.g. 21:57, 22:57, 23:57…). One light at 8% and the other one at 40%. I have not used any automations, scenes, scripts or schedulers at all so far. In the logs I see that the lights get switched by HA, but thats it. Any idea how i can fix this or narrow the issue down? That would really make my day! Thanks and best,
Tom
The HA KNX integration uses configured state_address or *_state_address to update the state of a function. These addresses are read by GroupValueRead requests on startup and when there was no incoming telegram for one hour (default sync_state).
If you have read-flags not set properly in ETS, this can lead to lights being turned on by wrong responses.
thanks for the quick reply. I have seen this in the docs before and checked the flags in ETS. From what I see is that there are all flags set for the 2 lights in question. Is there a special combination that should be set?
Yes, the correct one.
It depends on the object and what it shall do. Also, not only the flags of the actuator, but of all objects in a group address have to be set correct. That’s basic Knx, you’ll find documentation about that at Knx.org.
