A simple question, if during a watering period, the power supply is interrupted at the Rachio Iro, is that a signal is sent to the currently open valve so that it can close?
Yes all valves will close.
who, Rachio is the best. Thanks!
Can't take credit for this one, once the solenoids lose power they automatically shut off
another question around this topic...once power is restored to the rachio, will it finish the watering schedule or is that consider a stoppage event?
Power outage == stoppage. If the Iro is delivered new firmware which requires a reboot, it will finish watering the schedule, or if it disconnects/reconnects to WiFi will just continue as normal.
