Area_id control through the API not working

Configuration
1

Hi guys! I am trying to control my z-wave wall thermostats through the cloud. (HA ver: 0.103.6) If I will send POST request to
.....nabu.casa/api/services/climate/set_temperature
(with all correct headers) and body:

{
    "entity_id": "all",
    "temperature": 22
}

everything works, but when I am trying to control thermostats in specific Area that I created (with added thermostats to this Area of course), with the body:

{
    "area_id": "g316",
    "temperature": 22 
}

I receive OK 200, but nothing is happening. This way I used before the upgrade so I have no idea why it is not working now :frowning:
Thank you for your help,
Best regards,
Mike
