I have Modes set to change at certain times of day; Day mode at 8am, Evening mode at 5pm, Night mode at 10pm. I have a Hubitat C-5 and I am running release 2.3.3.140.
This morning, the Day mode change (and rules triggered by Mode changes) occurred at 7am and not 8am. Internally, I assume the Mode Manager must run on a timer, with the time difference between mode changes (10pm and the next day 8am) as the timer length. If so, this is not being adjusted for the overnight DST change.
I wouldn't change anything just yet. I'm pretty sure it will resolve itself at the next Mode change. I will provide an update this evening, at the next mode change time for my system.
Noticed the same. I suspect it's because the jobs were scheduled when they last occured, which was before the time change. My Morning Mode change occured an hour early, for example, and it last ran yesterday morning. I looked at the Logs and it's schedule for the correct time tomorrow.
