Homeassistant blueprint to set Tado offset using separate temperature sensor

I certainly didn't write/amalgamate this with that in mind. How were you envisioning it should work? When temperature readings differ between two thermometers, which one should be read? I'm not planning on maintaining this much further as I'm not planning on using it myself this winter. I've added right angle extensions to my radiator valves to move them further away and unfortunately I have a very busy job that has absolutely nothing to do with coding and am very amateur, so this takes much more time for me to fix than I have available and compared to how long it might take others.

The script works fine on one thermostat for me, but for rooms with more than one, the offset is not set. — Reply to this email directly, view it on GitHub <https://gist.github.com/1e9163c690e23bc8d32a8c9e9d89a910#gistcomment-4321971>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/AABJ7C5X26BFHJLXXE5XMQ3WBEXXVANCNFSM4ZNOPP6Q> .
