Replace DSMR device

My current DSMR reader is ESPhome based, but the reader will need to migrate to a place that is out of reach of the ESPhome API. There is WIFI in that area and therefore I have made a new DSMR reader that communicates over MQTT to my HA instance. So problem solved, except …

  • How take the historical information from the old DMSR device and add it to the new DSMR device.
  • Or what needs to change to the entities of the new DSMR device to map it to the old?

Thank you, YaNn
