Testing #26886

@rahulOCR Something odd going on here. get_temperature should be returning degrees-celsius, so the conversion I'm putting in here is incorrect.

Any ideas?

[rahulOCR]

get_temperature will return in degrees-celsius. can you let me know what odd is going on ?

Rebased on top of @rahulOCR 's fix (thanks!).
