This L7 give this error in the logs:

It does it after an hour or so, and need to be restarted to clear it. It doesn’t happen if the ambient air temp is kept very cool (18°C), but that may eat the margin that it makes unless it’s winter.
I’m guessing that this is a bad sensor because the other L7s that I have are in the same temperatures, and work fine.
Any ideas?
