I don’t think you understood my request. I would like to test the operation of the rain sensor feature, assuming the rain sensor works.
Right now, the only way to test my rain sensor feature is to wait until one of my regularly-scheduled programs starts, and then actuate the rain sensor.
This would be simple to do. Just make the rain sensor affect either the “test station” feature or the “run once” feature. Right now they both appear to ignore the rain sensor.
