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.
