Set DPL Upper Power Limit persistent from Home Assistant

[Matt5312]

Dear experts,

I am looking for method to set the DPL "Upper Power Limit" from Home Assistant.
I can set a value from HA via the MQTT publish method. The values gets modified in ODTU DPL but only for some seconds.
Afterwards it switched back to the Value defined in DPL Setting menue.

Example DPL hasset 100 W

If I am now set a new value from HA via :

The values changes (visible within MQTT Explorer) but after a second the default value from DPL Setting menue gets restored.
I was under the impresion the above MQTT publish would change the default value, but seems to be not the case.

Any idea how to adjuts the "Upper Power Limit" from HA persistent ?

Any hint is appreciated

Cheers
Matthias
