MQTT connection of venus os disconnects once per minute if grid meter and standard MQTT requests are operated in parallel #17

I have set up this enhancement to emulate a grid meter. I am sending once per second a new value to the venus os via this connection. When I also used the venus os MQTT for other communication the MQTT connection disconnected once per second for a few seconds. When I removed all the other MQTT connections and only left this one for the emulated grid meter, the disconnection did not happen anymore. There seems to be a conflict when using this MQTT connection in parallel to the other topics. I solved it for the time being by using the modbus protocoll for all the other connections i needed.

What does the log say? In the readme it is well documented how to troubleshoot.

When I observed the issue, I looked into the log file under /var/log/flashmq/current and could not find any error there. Unfortunately I did not store the log output. When I now reactivated the MQTT calls again, the issue did not pop up again. I have no clue why this was observable over days, then I reconstructed the calls to modbus interface and now reactivating the old status does not show it again. Anyhow, I will close it. Maybe someone else will stumble about this again.
