mqtt output only presents .../config data but no values #117

Hi

I have the docker installation running and MQTT is sending data, but all only config data, no values. inverter_poller shows real data. What do I need to configure to get real values for each topic via MQTT?

regards

same .. did you solve it?

No, unfortunately not until now.

same issue here

I've solved it for my Inverter: Axpert VM III TWIN 6000 watt 48V Off-Grid

TL;DR;

I've changed the following values in the config/inverter.conf

qpiri=99
qpiws=40
qmod=5
qpigs=120

How to get the correct buffer values

Find out the proper values is a bit tricky but with roughly 5 minutes can be achieved. It can all be done with a single terminal, but to speed up the process and reduce the amount of work needed to make changes and check them, I do recommend to have 2 terminals open, this can be achieved in various ways:

  1. connect with 2 terminals via SSH to the same instance from a third instance (the easiest solution)
  2. using TMUX session

Procedure

cd /opt/ha-inverter-mqtt-agent
docker compose up -d
  1. We then need to connect to the running container to check if the values are correct 
    docker compose exec -ti voltronic-mqtt bash
  2. Inside the container, run: 
    stdbuf -oL /opt/inverter-cli/bin/inverter_poller -d -1 2>&1 | grep incorrect
  3. Check if it output anything. if it does, it will look something like this: 
    Sun May 26 13:38:12 2024 INVERTER: QPIGS: incorrect start/stop bytes.  Buffer: (226.2 49.9 230.0 49.9 0161 0096 002 363 51.60 003 054 0041 07.9 064.0 00.00 00000 00010110 00 00 00410 011 0 00 0000
  4. That means we need to change the qpigs (that is in the log line just after INVERTER) because the line is truncated.
  5. Exit the container with the command exit
  6. Open the file config/inverter/conf with your favourite editor and increase the parameter found on point 4 by 1 
    qpigs=118

    become

    qpigs=119
  7. Save the file and start back from point 1 till you have no more lines with incorrect start/stop bytes
  8. To confirm all is fine, run: 
    /opt/inverter-cli/bin/inverter_poller -d -1

    and you should have an output like
