Rachio skipped irrigation wihout notice

Rachio gen 3, linked to Tempest weather station.

I’ve a schedule that runs all days except Wed. It waters “before sunrise” so it starts about 2:30am.

I’ve just detected that it didn’t water on Saturday. Looking at the logs, there is no “skipped” entry because of weather. Using the iPhone app, looking at the Calendar, the entry is not even there at all for last Saturday, although it is there for the next couple of weeks/months.

Any other more low-level logs I can look at to check why it didn’t water?

Another thing I’m seeing is that I’m having LOTS of power cycles per day. Maybe this affected the watering, but this shouldn’t (I guess) caused no records to be logged.

Any help is apprecitated,
