Humidity dropped from 91% to 4% during rain storm

It’s been raining at my house today and I noticed that suddenly my dew point reading was -25F, which didn’t make any sense in the middle of a rain storm. When I look at my relative humidity reading it went from 91% (reasonable during a rain storm) down to 4% (not reasonable during a rain storm).

My station ID is 21564.

definitely something wrong. It’s not calibration going wrong, sensor doesn’t show failed …
rebooted hub and Tempest but solution neither

I’m afraid you’ll have to open a ticket with support. This needs more detailed examination I can’t do. Sorry this is happening.
