[Custom component] Kostral KSEM and Enector

I am currently working on a new integration for the Kostal KSEM smart meter and the Enector wallbox.

I would be happy about feedback and suggestions

Hi @MeisterTR,
Many thanks for creating this integration. I installed it via HACS, but having trouble to retrieve data:

All Sensors are “unknown”, only the Diagnostics seem to work.
Any chance you could think of a solution for this?

great idea… I was just about to start digging into Modbus for this…

However, could there be some problem with number conversion?

I definitely don’t have 25 MW (Megawatt!) from my battery.

I am happy to assist in debugging!

Regards
Matthias

Hi, I was able to solve this issue by enabling the TCP Slave in the KSEM:

Now it works as it should! Many thanks for the integration!
