Devolo MT02755 sensor cannot be configured

[Solderbro]

For two humidifier i just bought two Devolo MT02755 sensors, these can be included and excluded without problems. Blockly works nice with their output.

Devolo home Control Humidity Sensor MT02755+
Devolo home Control 0x0020 0x0002

The one thing that is impossible to change is their config, the device page as also the openzwave panel send my changes out and after few seconds the devices jump back to their default. This is for example Fahrenheit for the temp and this is no fun in Europe.

Do we have a successor changing the Devolo config?
