Homebridge not picking up units of Nest on initialization

[gonenutsbrb]

Sorry for the random issue right in the middle of the holidays.

I just re-setup my homebridge install and it now appears that when starting homebridge, it doesn't pick up the units of the nest. And even when changing the units in the Nest app back and forth as suggested in a different thread, it still doesn't show anything in the logs.

I do see the expected error regarding the software-version characteristic, but nothing else:

So I do have Siri giving me correct units (Fahrenheit) and the nest displaying correct units, but the logs show Celcius (see below) and it causes Siri to respond with decimal based responses (which may be a different issue).

No rush, but any ideas?

+1 for this issue except I'm seeing incorrect temperature in Home app compared to the Nest app. Home app is always off by -1 degree using F units.

I'm seeing the same behavior. Siri is responding with the decimal points, i.e. "Hey Siri set the temperature to 72-degrees" -> "Ok, I set the temperature to 71.6-degrees fahrenheit."

Looking at the logs:

[2018-1-4 10:40:58] [Nest] Trying to set temperature 22
[2018-1-4 10:41:03] [Nest] Temperature set to 22

22C = 71.6F

I just set up Homebridge and homebridge-nest over the holidays, so perhaps this is an issue with a newer version of the API? The API version was 1 or 2 versions higher for most of the permissions requested.

Found the issue with decimal rounding and will submit a PR shortly.

On a side note, I've also found the logging for new API is slightly different than before. In the logs all temperatures will be reporting in Celsius, which is to be expected. You will also not see any logs detecting the units.
