I’m travelling so I cannot check the sensor properties. But it must be a clock-related problem. Right now, 15:30 local time, the app report sept 09, 23:59 !!
I’ll keep checking the time on the app from remote.
Edit: definitely a clock problem. Local time 19:14, four hours later: and the app reports sept,10, 02:31. The NTP sync is enabled. Should I disable it ?
GMT is set to +2:00 as it ever was from the start.
