I've been assuming I'm getting someone else's temperature readings, but I'm not sure it makes sense either, because this is my third choice of "ID" settings for my temperature sensor since I started reconfiguring it, and I don't live in a dense enough area for there to be this many sensors on all kinds of settings.
Is there a way I can try to figure out a "free" ID without a lot more trial and error? Could it be caused by something other than a different sensor with the same ID? Has anybody else had these kinds of problems?
