I had a number of time related issues, UTC instead of local, log times 12 hours ahead of actual.
My issue was resolved with the latest update AND re-installation of Rule Machine, Mode Manager and 1 device that still showed incorrect times.
Not exactly your problem, but problem with times none the less. Also in my ticket requested a display of local time of the hub within the location or settings page.
The last update partially fixed the issue, but required re-install of mode manager, and automations for it to work. There are still time related bugs that I understand are being addressed in the next update. It has to do with some parts of the system using UTC and others using local time.
I just got it two or three weeks ago and haven't rebooted it yet, as far as I know.
While we are at it, the log shows a ton of activity and I don't know why. I have one bulb on my system, that's it. Trying to decide whether to switch from another platform to this one and wanted to test the waters starting small.
