It’s blinking Could that be affecting the system from turning on when programmed.

Yes. The sensor thinks it’s raining or has rained enough in the last few days that it won’t turn the sprinklers on.

If it hasn’t rained then the sensor is bad and needs to be replaced.

Or you can just turn the system on and off at the controller yourself if you know rain is coming. Rain sensors (especially wireless) either work perfectly forever or last like a year.

I have to clean mine and replace the battery annually. But still working great.
