Receiving notification of rain sensor activated/deactivated every few minutes

I’m just wondering what I need to do to troubleshoot the problem with the rain sensor. I’m receiving a notification the rain sensor was deactivated and then about 10 seconds later another notification the rain sensor was activated. This on/off behavior repeats many times per minute. The log is littered with these notifications – I eventually had to turn off notifications. How do I correct this problem – Rachio Gen 3 controller box. Problem just started occuring this week, prior to this week I never had a problem. Software wasn’t updated or any change made in the system since installation about 3-4 months ago

Some troubleshooting here might help. Could be a dirty or stuck rain sensor.
