We have one of those Acurite weather stations that has a bunch of various other sensors that you can put different places and check them all from an app on your phone, and one of the sensors is in my BP's cage (it's not the only thermometer in there, there's a standalone unit thaat predates it). At one point for some unknown reason, that sensor registered a temperature of 350 degrees, I kid you not. Obviously there is nothing in there that could possibly reach that temperature, and the sensor hangs from a platform at about mid-height, so it didn't fall in the water dish or anything. It just decided to show me 350 degrees momentarily for no apparent reason.
Other than that one reading, everything was totally fine, but I definitely had a "holy !@#$!!" moment when I saw it!
