Humidity / Dewpoint Spikes and Drops (pic)

I checked this thread here. https://cumulus.hosiene.co.uk/viewtopic.php?f=13&t=7678

Its slightly different than my situation.

For some reason my humidity levels are too high and too low. As you can see with the graph it was 100% overnight and 30% now.

Dewpoints are generally in the 60s in the entire area and humidity closer to 50%. I also noticed the heat index is lower than actual temp. In reality it should be around 91-92 value at this point.

So I'm wondering how to use the spike removal tool. The help section explains it nice but I'm a bit confused on the "percentage" value. Do you have any thoughts on how to avoid these drops and spikes without constantly changing the multipliers?

The spike removal tool isn't going to help, because you're not getting spikes (sudden freak changes in reading which then return to a sensible value). If your humidity should really be around 50% for the entire duration of that graph, then I think you simply have a faulty sensor.

I was worried about that.. I wonder if its the batteries going low. Havent changed them since last fall.

3 weeks ago I did lift it 1 foot higher then shown here because I was thinking the roof heat was drying it out during the day and at night moisture building on it. Doesnt seem to have helped.

The FO screen isn't enough to cover all the solar radiation and can provoke wrong humidify and temperature values. Try searching around the forum for ideas for better stevenson screens, they're all over
