Domoticz

All
I have a Domoticz Version: 2023-1 running on Raspberry4 and i try to monitor my Solar installation based on SOFAR inverter with LSW3 wifi Dongle.

I found and install from "Sofar_LSW3" API found in Gitub
This API use MQTT , I install it on the raspberry including MQTT client
Everything installed and configured properly (i guess)

Using MQTT explorer I can see that API is reading the data from the Inverter

On Domoticz I created the "MQTT client gateway with LAN interface" called SOLAR

Starting this point i am lost and did not succeed to get any Device updated.
Note: The hardware "MQTT..." did not allow virtual sensor creation

I get in Domoticz log the following error "Error: SOLAR: disconnected, restarting (rc=14/Protocol error)"
I googled the error and did not found any relavant answer.
Did not see what I am doing wrong.

Hello @jool91,

It is clear to me, why this will never work.

The MQTT interface into Domoticz requires a specific syntax. Like http.
You can find this at https://www.domoticz.com/wiki/MQTT

The MQTT output of your API, which you see in MQTT Explorer, does not match the requirements of Domoticz. You will need a conversion. Node-RED is the tool to use.

See: https://nodered.org/

Thanks FireWizard

This was not clear in the installation / configuration a read.

I will have a try installing NodeRed and let you know

Brs

There is now an alternative Python plugin that can map unsupported MQTT messages to Domoticz devices through a configuration file:
