Gen 3 with Rain Bird WR2 Rain Sensor

post by gross7777 on Jul 19, 2023

Early this morning the system started watering as normal. It started to rain so the sensor activated at 4:45 AM. The system stopped watering. The sensor Deactivated at 5:18 AM even though it was still raining and the system resumed the schedule and finished watering. All while it was raining pretty heavy. I followed the wiring procedure for the WR2 sensor so I’m not sure what the issue is.

It appears it hardly rained any so your sprinklers finished off their program. That is normal operation.

You can lower your rainfall setpoint (it’s 1 notch from half right now) down1 more notch which will trip the sensor earlier and keep them off for a little longer if you wish.
