I sent the question below to support, but if anyone has any ideas it would be appreciated.
I installed a rain sensor (Toro 53769) using your instructions at,
Currently the black wire is connected to R1 and the red wire at R2. I tried it the other way as well. When testing using the Toro instructions, the app shows it raining, but the sprinklers don’t off.
Is there something else I should be doing?
