Nest current temp and the set temp are not showing correct in Home app about homebridge-nest HOT 10 CLOSED

v2.1.2 should now have this fixed. let me know if you experience otherwise

Homebridge shows that the nest has the heat turned on and that it is set to 64 and that it is 66 in the house. The Nest app and the physical Nest shows that it is set to 65 and 67 in the house.

weird. can you:

1. shut down homebridge
2. launch homebridge in debug mode DEBUG=* homebridge -D
3. attach the log once homebridge is up and running.

launching in debug does not work, possibly because I installed using docker? Maybe that is also why the temp is wrong?

from homebridge-nest.

is there a way to run it in debug mode within docker?

sorry, I'm not familiar with that setup

I'm having a similar issue. The Home app says Nest is set to "Heat to 66" but the Nest device is actually set to heat to 67 (as indicated in the Nest app and on the physical Nest device). Unfortunately, I can't run homebridge in debugger mode because I have it running as a Hassio (Home Assistant) plugin. I thought this issue was brought up in the past and some updates to the code were made based on some rounding errors, but it appears the issue may still exist. All of my temps are in Fareinheit.

I think I see what's happening; the °C numbers from the API can be wrong when in °F mode. E.g. the API will say it's 19°C when the temp is 67°F, even though (67-32)/1.8 = 19.44. Right now the code only looks at the °C values because HomeKit only talks °C anyway. Looks like we'll have to detect °F mode, take the °F value, and then do our own conversion to °C.

Updated and the temp seems to be spot on now. Thanks!
