core: Airzone integration - systemid out of range

The problem

Trying to setup the new Airzone integration from 2 different HA instances, I get an unknown error (the system is working fine both with custom sensors anche with HACS Airzone integration).

the output of curl -s --location --request POST "http://AIRZONE_IP:3000/api/v1/hvac" -d '{"systemID": 0, "zoneID": 0}' | jq

is: { "errors": [ { "error": "systemid out of range" } ] }
