Rain Bird WR2 deactivation message

I have wireless rain gauge / freeze installed on my Rachio 2. When it rains it sends a message " activation " then with in 15 minutes " deactivation “. The rain set point is set at 1/4” and the last week we have gotten 1/2 ". So why does it activate so soon. I assumed it would stay "off " till the rain reservoir went down.

Hey @wtp11,

When’s the last time you cleaned your rain sensor? It sounds like it may be time based on your description. Directions on how to do that can be found here.
