Problems publishing collected data via MQTT

[hwinkelmann]

Hi,

I am struggling with the export of the harvested data via MQTT to home assistant. The data collection works nicely, in the web UI, i get a nice list of address registers and values, and the data is looking good, including the serial number. However, pushing that data to mosquitto fails.

I could post the entire debug log, but a whole lot deals with the state machine collecting the modbus data, which is obviously working fine. So I've reverted to the info log level, if that's not enough i'm happy to provide the debug log.

I am no python dev, but the first line looks like a syntax error?

The addon's config looks like this:

host: 10.0.0.158
timeout: 10
scan_interval: 30
connection: modbus
smart_meter: false
custom_mqtt_server: false
log_console: INFO
model: SH6.0RT

If you have any questions, please let me know! And thanks for your work!

I’ve seen this error mostly when mosquitto doesn’t run before sungather starts or gets restarted. Sungather misses some resilience here.

[hwinkelmann]

I've disabled sungather and restarted the system and home assistant. Once mosquitto was up, I've started sungarher again. But the log looks still as above, so I assume it must be something else 😕

Misclicked, sorry

For me it helps to downgrade paho-mqtt to version 1.6. There is a breaking change in version 2.0

Could you explain a little about how you did this please?

@baylf2000 I am having the same issue. @LokAndFeel how can you do this? I am current running Mosquitto in a Docker container with no issues with other containers.

Hi

This issue is the model is not detecting correctly, and the model makes up part of the MQTT topic.
Setting the model manually in the config will fix this.
New version will fix this.
