Hello,

i get successfull the MQTT running in my Venus OS , i see the MQTT Energymeter . But all Values are "0" . I Think i have to format the Publish String correctly .

I tried some things but it doesn´t work.

Here some examples shown in the Mqtt Explorer :

sensor = value" "Power_curr" -514.0 = value"1234","Power_curr" -428.0 Zaehler = value"1234","Power_curr" -507.0

i want to transfer only the actual Power , to get the ESS running on the Venus os.

best regards Ronald

I dont think that the author is still active here. but you could check out this mqtt meter: https://github.com/mr-manuel/venus-os_dbus-mqtt-grid

You should get a json on: zaehler/h_1evu/SENSOR with the following included ["Zaehler"]["Power_curr"]) ["Zaehler"]["Total_in"]) ["Zaehler"]["Total_out"])

These can then used.

But for easier use, try the DummyMeter and fill that with NodeRed (LargeImage). Much easier and better to understand. https://github.com/Marv2190/Victron_DummyMeter_NodeRed
