HAMA Thermostat 176592 + Zigbee2mqtt - heating: NULL with applicationVersion”: 85

With 3 pieces (I get the status “Heating”), with 10 pieces no status.

The only difference is the applicationVersion:

  • 3x “applicationVersion”: 67 works: “heating”: “ON”
     {
         "anti_scaling": "ON",
         "away_mode": "OFF",

Do I need to update the firmware for the 10 and how can I do that or is there another solution?

Thanks.
