core Air return temperature display at 32768°C,

The problem

I use several Aidoo modules on an installation. They work correctly even if they are often unreachable via airzone Cloud. However, they are still functional via Home Assistant and the local network, which is perfect. However, there is a bug with the firmware 10.13/6.20.

The temperature reading does not work and displays 32768°C. This should be the air return temperature (which is used as a measurement for the regulation). The three modules display 32768°C, and this value is fixed and unrelated to the actual temperature of each room.

See attached.

Thank you for your help.

@Noltari here they are

config_entry-airzone-01JPWNVGP7MX4HVP2SCZM24Q38.json

@okp90 I can see that the Local API is returning those values:

"temp_return": -3276.8,
"work_temp": -3276.8,
"roomTemp": 32768,

Unfortunately there's nothing that we can do from our side since it's a FW bug. Please, report this to Airzone so that they can fix it with a FW update.
