First time I’ve seen this one. It just paused with a Rain Detected message and started to return to the dock. I checked the sensor and it’s sitting at 0 with a detection threshold of 200. I turned it off in Preferences and continued. Any other reports of this?
First I’ve heard of this. I thought the same thing once and then I got the alert from my weather station that it was raining. 
It’s odd to be at zero though. Usually there is natural humidity it detects.
Hopefully just a one off, and yes I’m used to seeing some low value as well.
Hi there, this is abnormal. Yarbo should not return to the docking station when the rain detection threshold has not been reached. This may require further investigation from our team.
