Hello,

today I received an update notification from Homeassistant for all my LYWSD03MMC-z devices. I tried this update with one device after the update was successfully the devices resets the calibration settings and the icon on the display which was previously disabled enabled.
I tried to disable the icon on the display first and recognised that I cannot change any value from settings menu in z2m.

when I try to change the icon on the display I receive the following error:

Error 2024-08-17 17:22:27z2m: Publish 'set' 'comfort_display' to 'Temperatursensor Ankleidezimmer' failed: 'Error: ZCL command 0xa4c1381b6dd38292/1 hvacUserInterfaceCfg.write({"2":{"value":0}}, {"timeout":10000,"disableResponse":false,"disableRecovery":false,"disableDefaultResponse":true,"direction":0,"srcEndpoint":null,"reservedBits":0,"manufacturerCode":null,"transactionSequenceNumber":null,"writeUndiv":false}) failed (Cannot write USE_DATA_TYPE without dataType option specified)'
