Hi, it works! And i discovered my newby mistake what causes this. Reason is that i made an extra zone 5 (with no sprinkler connected) to simulate in parallel two schedules, one fixed (as advised in the first few weeks) and one flex.
I did press manual activation on the zone screen, not on the schedule screen. Stupid and apologies!!
Solved and hope i did not cause too much research effort. But my already positive opinion of the service and commitment of the rachio team had been confirmed.
