We have fixed UTC times, and moisture graphs will now display the device timezone, will try to get this code out in the next week or two.
You might just have to trust that they will run when you zero out the moisture. I promise it will.
I think what is throwing you off is that we clear out the previous day (since today is affected by ET and precipitation and is dynamic). By clearing out yesterday (or filling), flex will still show you the forecasted irrigation. That might be what is confusing. Forecasted irrigation will actually be real irrigation when the scheduled time is supposed to run again.
Also, if you want it to water more frequently you could decrease the managed allowed depletion on the zone.
Trees are a little more difficult with flex schedules since we assume a 24 inch root zone depth which means a long interval in between waterings. Depending on the tree's actual RZD, this might need to be adjusted.
Hope this helps. If you want [email@example.com] to review your schedule you might want to shoot a quick email to them.
