OK, keeping a sensor from getting false readings due to radiant heat is a serious PIA. I refuse to buy something premade, even if I could find it, but I’m starting to come up with a lot more “doesn’t work” then “almost works” solutions. I’m taking a little break over the next few days to get some honey-do list stuff done (landscape, sheet rock, paint, etc) but more soon.

I had a similar problem. On a hot day my temp sensor was as much as 30F degrees off. I actually used one of my kids thermal lunch bags and a ziptie to address the problem. My temp sensor is mounted under the eaves and gets too much radiant heat from the roof tiles. I put the temp sensor in the thermal lunch bag with my lead wire coming out of the open end of the bag and used a ziptie to keep it in place.
Hope this works for you too.

That is so great ! I would love to see a picture of that! I found a mounting spot where I can mount the sensor vertical and your idea has me wondering if a plastic thermos would do the trick. We get everything from 110 degree heat to 18 inches of snow and gold ball hail, so now I’m thinking something sturdy like that would fit the bill. Thanks again!
