I vaguely remember a topic where someone wanted to check the temp inside their fridge.

Yesterday I bought one of these in Lidl

If you put the end of the cable with the censor on it in the fridge and shut the door you get the temp in the fridge and in the van .........and even a clock all for 3 quid ............can't be bad.
