I have a Gen2 installed and accessing my PWS. This past week we had over 4 inches of rain. On one day we had 2 inches and the next day the system turned on and I received a message that the system would run because no rain is predicted for that day. All of a sudden it appears that the system is not using past levels of rain to determine future runs. My system is set to not water if we get .25 inches of rain. My PWS is an Acurite. Rachio support says it is because of the moisture level calculation. Something has obviously changed as I have had the system for several years and never had this problem before.
