I have a Rachio Gen2 with a wired Hunter Mini click rain sensor that is just 2 years old. I’ve read others having the same issue of MULTIPLE duplicate notifications that their rain sensor has been activated and deactivated. I have also read on the forum that they have been instructed to check the wiring or clean the rain sensor. I installed my rain sensor just 2 years ago and for all that time its worked perfectly, therefore, I believe my wiring is correct. I also went on the ladder made sure the unit is clean and even pressed the tab on the top of the unit to make sure it clicks and makes contact. I truly feel with so many of us having the same issue, it’s not a wiring or hardware issue, which only leaves a possible software issue. Its rained here in NJ for the past 7 days, so my sensor still shows activated, but previous to this, I kept getting rain sensor notifications like crazy stating activated, deactivated for at least 4-5 times a session before it settled down to activated.
Just wondering if a problem has been identified and has been resolved. Love the Rachio Controller! It has saved me tons of money with my water bill not to mention the convenience.
