Bug in "Automatisierung"

In an arrangement with a sensor controlling a light / group (“Automatisierung”, sorry my deCONZ is in German) I encountered a bug. Occasionally it happens that, when editing daytime segments (enabling or disabling a segment), the five system generated rules “pir-xResControl-…” disappear. These rules apparently are responsible for clipping activation at the daytime segment boundaries. In effect, light activation by the sensor would be enabled 24h a day, despite at least one disabled daytime segment.
Work-around: enabling / disabling some segment until the rules re-generate, or set up the whole machinery from start.
It’s not a problem for me, since I know now how to handle it. But someone should have an eye onto this.

BTW: I would consider it an improvement, if the noon and midnight boundaries were fixed, and not dependent on sunrise / sunset. Otherwise these times move during the year considerably.

I have also seen this problem with Automations. I have two outdoor sensors that are set as triggers for a group that should only turn on the lights when it’s not daylight. I set the system up and all is fine. If for any reason I reboot the Pi running Conbee then this automation will resort to working all hours of the day instead of the two night time settings I chose. If I delete the automatic and add it back in then it will work properly once again. Same as the author if this defect is seeing.

I have the same problem after a reboot.
The sensor and automation stays but in my case it won’t switch on the lights anymore instead of switching it all day.

Could it be a rights problem with Linux? I’m using Ubuntu 24.04.

Seems like beta 2.31.0 fixed it for me.
