ray, I am sorry, I phrased my problem rather badly. I am not having issues with the rain sensor or operation of my ospi. That is working like a charm. My issue is the notification via IFTTT. Notification about a program start is being sent even if rain sensor is tripped and even if the whole system is deactivated. This is not how it is supposed to be. Why send notification about program start when in fact nothing is happening.
