Homegear update

Hi all,
I am trying to use Homegear to connect my MAX! devices by means of a CUL interface; (original MaxCube has died…)
Basically connection works and I can see my thermostat (valve) devices
BUT
It does not update… I can see values (temperature, valve %) change only when i restart Home Assistant (restarting Homegear does not take effect)
Any suggestion?

This is snippet from my configuration file

homematic:
  local_ip: 192.168.1.251
  local_port: 36845
  interfaces:
    wireless:
      host: 192.168.1.251
      port: 2001
      callback_ip: 192.168.1.251
      callback_port: 36845
      resolvenames: json
      username: !secret homegear_username
      password: !secret homegear_password

Thank you
Michele

My system works with this configuration:

homematic:
  local_ip: 192.168.1.251
  local_port: 36845
  interfaces:
    wireless:
      host: 192.168.x.x
      port: 2001
      callback_ip: 192.168.x.x
      callback_port: 36845
      username: !secret homegear_username
      password: !secret homegear_password
      resolvenames: metadata

The json format is depreciated. I have it in metadata.
I work with a modified MaxCube like this: https://community.home-assistant.io/t/converting-a-max-cube-to-cul-cun-to-use-with-home-assistant/74218

Everything perfect in two years of work
