Hi  
I have a weatherflow smart station which has recently started to read 20% high on the humidity measurement. My davis PRO2 is currently reading 59 %, whereas my smart station is reading 78%. It has been like this for weeks, even before my hub died. I have been hoping it might calibrate, but no, it’s still reading 20% high all the time.  
Any ideas as to the problem?

Thanks

without any details about where your station is set regarding ground, surroundings etc … very hard to tell what might influence

Station is about 3 weeks online seen server side and none of the calibrations kicked in. All results failed QC and that’s how far I can see.

Hi  
Thank for your reply, it is in the same place that it has been since the initial installation over a year or so ago, nothing has change in the area. It is 6ft off the ground in a clear area free of anything that could affect it.  
Best Regards
