@nexux78 this may be related to the Power Meter option in the OpenDTU-OnBattery. I understand that you want to have a MQTT Topic which OpenDTU should use for its display. This hints at the question whether we want to integrate the Power Meter (and by logical extension also the Dynamic Power Limit 😉 ) feature from OpenDTU-OnBattery into OpenDTU.
