Subject: Remove unused read_temp() function
X-Git-Url: https://the.earth.li/gitweb/?p=temper-clone.git;a=commitdiff_plain;h=267a3bfd1e8892f8ae75bc4b3d1a5c4b310f1805

Remove unused read_temp() function

The temperature is read as part of a state machine in the main loop so
we don't tie thing up for too long, so this is no longer necessary.
