Negative HVAC temperature value

I’m using Gree Climate integration to drive my Gree HVAC with wifi equipped.
This works well without any configuration (Congratulation for a so simple installation !!)
The only problem I encounter is the current temperature displayed. I see only negatives values in actual temperature. It displays -17°C (so cold !!). For information it makes around 0°F so it could be a wrond read value ?

Any idea ? Is there wome log I could provide ?

I’ve try to add some log but even in debug level I have only this frames:

2021-10-05 21:04:47 DEBUG (MainThread) [homeassistant.components.gree.bridge] Finished fetching gree-0df83d7f data in 0.107 seconds (success: True)
2021-10-05 21:05:47 DEBUG (MainThread) [homeassistant.components.gree.bridge] Finished fetching gree-0df83d7f data in 0.111 seconds (success: True)

Problem seems to be located on greeclimate lib. I have open an issue on my investigations on the repo
