S0 Impulser from volkszähler in Grafana


I am new here, I came from Germany, so sorry for my bad English.

I found this Thread here Display S0-Impulse Values

But the result works not for me, I think I don’t understand correctly the 300 in this line.

I have the same Values, always 1, the timestamp is different. I just MariaDB, the latest Version.

My Energylogger gives me 150/kWh
Can anybody help me? What is the Correct code to display it in Grafana?

Best Regards
