@Markinus did a great job with the plugin based on the limits we all have with KM200. It is really to bad for all smart Home enthusiastic people out there how closed such useful information could be even in just a read mode! I now changed to esp-ems that offers quite all information you can read manually on your device including all energy based elements in real time. You get also some really simple information like what this stu++I’d thing is doing currently or even if it is active. You just need a ESP32 or 8266 / Arduino / RPI and a EMS extension board + a cable into your heating system to connect to the EMS bus ~ summed up around 50 bucks and that’s it. You get all you need pretty simple over mqtt whenever a value changes.
