Hints:
Inverter: EASUN SPL5K (also labeld as POWLAND or EFFEKTA AX-M or K 5K)
Raspberry Pi: 3B+ (connect with USB-Cabel on EASUN)
RaspbianOS [since 12/2024]: Bookworm (based on Debian 12 Bookworm)
UseCase: I use the fabulous mppsolar-package to configuration of my equipment & monitor working conditions.
Security: Think about your Usecase! Expose this Constellation never ever in Internet! Use safe passwords for admin-users or use ssh-key-based procedures for operation system and web server applications, use also the transport layer security from grafana. Is your usecase bigger as the home wi-fi, you should it leave security-professionals. In particular, the database and Grafana should be examined more closely.

Documentation:
OS-Image-Installation (Lite without Desktop and other) with Raspberry Pi Imager Tool on a 64 GB SDCARD (Don't forget the previous settings for Password, WLAN and SSH!)
After first login you should actualize your operating system.
Than you install by
sudo apt install python3-full libsystemd-dev
before you execute the pip-Installer.
In my Envoiment i use the installation command
sudo pip3 install --break-system-packages mppsolar[systemd]

As next, i follow the original docu: https://github.com/jblance/mpp-solar/blob/3b500bd494477c1d3b0824823f8a43aa9a135711/docs/service-README.md

As next, i follow also the documentation for MQTT ...: https://github.com/jblance/mpp-solar/blob/3b500bd494477c1d3b0824823f8a43aa9a135711/docs/MQTT_Influx_Grafana.md

Note 1 General:
both repos from grafana and influxdb have problems with gpg-Security,
you should fix them, as the project docu describe:
https://packages.grafana.com/oss/
https://repos.influxdata.com/debian/

Note 2 to InfluxDB: before you use the database-Client influx per command, you must install them with sudo apt install influxdb-client

sequal follows

Telegraf seems to have a problem with the INPUT parser.
Maybe someone will see it:

I mean, all is normaly!

This is complete!

Telegraf configuration input/output

pi@raspberrypi3:~ $ cat /etc/telegraf/telegraf.d/mqtt-input.conf && cat /etc/telegraf/telegraf.d/influx-output.conf 
[[inputs.mqtt_consumer]]
  servers = ["tcp://127.0.0.1:1883"]
  topics = [ 
    "#",

  data_format = "influx"

pi@raspberrypi3:~ $

Using the troubleshooting commands I can get measurements into the database. It really seems to be a Telegraf input parser problem. The mpp-solar command is QPGS0 and the protocol is PI30.

I experimented with the input topic.
If I replaced # with EASUN/settings/# the INPUT plugin error did not appear.
However, the database had no content either.

I don't fully understand the documentary yet: https://github.com/influxdata/telegraf/tree/master/plugins/inputs/mqtt_consumer

But I think I need to look into it more.

But maybe someone had a similar problem?
After all, everything worked until the SD card broke.
I didn't have any other hardware at the time.

What output module are you using? I think from memory telegraf needs a different message format

Thank you for your answer. I tried it.
But the telegraph service didn't start.
I think, the problem is my topic design.
I'll be dealing with it throughout the day today.

It shouldn't stop telegraf from starting - even if mqtt messages are completely wrong. What format messages did you get? What errors did you get on telegraf?

Which function have the "#" - sign in topic-directive?
Is this a placeholder for the payload from the inverter?

It's a wildcard for mqtt topics, in this instance it means all topics that start with /EASUN/status no matter how many more parts there are

What did you change that stopped the telegraf service? I was talking about changes at the mppsolar end of the pipeline

First I used Telegraf as documented.
The Input-MQTT plugin only had the wildcard "#" as a topic.
This causes the plugin to crash and outputs line after line of the message as an error of the plugin.
See here:

If i change the topic to "/EASUN/status/#", this error disappears.
However, nothing arrives in the database.
I'm sniffing with tcpdump on localhost tcp/8086.
Nothing arrives this port.
So the outport-plugin or the data-processor doesn't work. I don't know.

Either this is a bug in the current version (actually version 1.33)!
In Telegraf versions 1.26 and 1.28 the configuration with topic "#" worked without any problems.
Since these versions, some changes have been made to the MQTT consumer plugin. Maybe the parser now expects something different than what I give it with "mpp-solar -c QPGS0". I don't know.

Here the changelog from telegraf: https://raw.githubusercontent.com/influxdata/telegraf/master/CHANGELOG.md
That's my modest research. I'm not competent enough when it comes to coding the plugin.
