I need a little help with signals from my battery monitor. There are variables voltage values e.g. 48456 in mV from MQTT. I see the values in Nodered.
Now I have to give this value a name as this sequence: Name:value --> BattMinU:value
I tried for my experiance all, but not the solution.
Then I can include this value to my Emoncms logging.
It works with signals from my SPS with this view, but this are fix values and not variables.
Can somebody give me little help, please
