Hot spot reading Higher than uth setting

I'm glad you caught that. Unfortunately, the strength of the adhesives for most of the stick-on UTHs can be pretty variable, so I don't rely on them to stay on their own, even when installing them brand new. I'd recommend securing all your UTHs with a strong, heat-safe tape, such as foil tape.

And to add to that I would make sure the probe is flush and up against the uth with tape. You don't have to necessarily cover the probe tip with tape but on the bottom of the probe and the wire. In other words you want the probe up against the uth.

(Asking for other posters thinking ) Would it work to tape the probe tip to the bottom (outside of course) of the tank instead of against the heater pad. It needs to be one or the other right? Which way is better posters? I don't have a ton of UTH experience.
