Mqtt Component communicating with Mqtt server

[snaven1]

I have had Sungather working flawlessly for the last year without issue. I upgraded the base operating system from Fedora 36 to Fedora 39 This broke Sungather completely due to various library issues. I was forced to reinstall SunGather as per online guide. This went well without issue. Using the same configuration file, SunGather will not communicate to my MQTT server (different box), otherwise works correctly in terms of extracting data from the SunGrow inverter. This is the error I am receiving.

Mar 11 10:36:06 hsmart.homebase python3[34892]: 2024-03-11 10:36:06 WARNING MQTT: Server Error; Server not configured Mar 11 10:36:06 hsmart.homebase python3[34892]: MQTT: Server Error; Server not configured Mar 11 10:36:06 hsmart.homebase python3[34892]: 2024-03-11 10:36:06 INFO Next scrape in 15 secs

On using mosquitto tools ($mosquitto_pub) from the same machine, this works correctly and talks to the mosquitto mqtt server. I have also included a snippet from my configuration file (config.yaml) related to the mqtt server part

— name: mqtt enabled: true # [Optional] Default is False host: 192.168.100.86 # [Required] IP or Hostname of MQTT Server port: 1883 # [Optional] Default 1883 topic: "SunGrow/SH10RT/registers" # [Optional] Default: "inverter/{model}/registers", Variable {model} will be replaced with model number of inverter username: "mqtt" # [Optional] Username is MQTT server requires it password: "mqtt" # [Optional] Password is MQTT server requires it client_id: "SunGather1" # [Optional] Client id for mqtt connection. Defaults to "SunGather", need to be set to different values if you want to run multiple instances of sungather. homeassistant: True # [Optional] Default False, Publish discovery and sensors for HomeAssistant ha_discovery: False

Thanks for any assistance

Start the script with debug logging and grab the first 20 odd lines. My guess is the model isn’t detecting right which is part of the MQTT topic.

After running script manually, with debugging .. the critical part of the log related to the mqtt issue is as follows ...

2024-03-11 11:31:25 INFO Loading Export: exports\webserver 2024-03-11 11:31:25 INFO Webserver: Configured 2024-03-11 11:31:25 INFO Loading Export: exports\jsonserver 2024-03-11 11:31:25 INFO JSON-Export: Configured 2024-03-11 11:31:25 INFO Loading Export: exports\mqtt 2024-03-11 11:31:25 ERROR Failed loading export: Unsupported callback API version: version 2.0 added a callback_api_version, see migrations.md for details Please make sure mqtt.py exists in the exports folder Failed loading export: Unsupported callback API version: version 2.0 added a callback_api_version, see migrations.md for details Please make sure mqtt.py exists in the exports folder 2024-03-11 11:31:25 DEBUG Checking Modbus Connection 2024-03-11 11:31:25 DEBUG Modbus, Session is still connected 2024-03-11 11:31:25 DEBUG Scraping: read, 4949:50 2024-03-11 11:31:25 DEBUG load_registers: read, 4949:50 2024-03-11 11:31:25 DEBUG Current transaction state - TRANSACTION_COMPLETE 20

The mqtt.py file is located correctly and with full read permissions available. Unable to find any migrations.md file?

Thanks

Problem solved. The Paho Python MQTT module needs to be downgraded from V2 to V1.6. Essentially, the V2 Api is incompatible with V1 scripts, hence the downgrade. The solutions are outlined at the following URL https://stackoverflow.com/questions/77984857/paho-mqtt-unsupported-callback-api-version-error

Hope this helps

I am having a similar issue with a new setup (haven't yet successfully connected to MQTT). I am running Mosquitto 1.5.5 and Sungather in Docker containers but I get the following: 2024-09-08 23:56:45 INFO Loading Export: exports\webserver 2024-09-08 23:56:45 INFO Webserver: Configured 2024-09-08 23:56:45 INFO Loading Export: exports\mqtt 2024-09-08 23:56:45 ERROR Failed loading export: 'NoneType' object has no attribute 'replace' Please make sure mqtt.py exists in the exports folder Failed loading export: 'NoneType' object has no attribute 'replace' Please make sure mqtt.py exists in the exports folder

Any help would be appreciated. MQTT works for other docker containers integrating with HA so I don't believe it is the actual Mosquitto instance
