MQTT Issues - reconnects and status

[stomko11]

Describe the bug
I have configured my MQTT details. It connects fine to the server, I verified it via mqtt explorer, device is correctly reporting all the values. However there are 2 issues:

1. webinterface of EVSE always shows "disconnected"
   

2. I see lot of reconnects on the mqtt server, like every minute. I found topic SmartEVSE randomly goes to unavailable in HA when connected via MQTT #115 which seems similar to what people were seeing, but it suggested fix would be incorporated in 3.7.0. I am on 3.7.2

Published state on mqtt server in SmartEVSE-xxxx/connected topic (mosquito addon in HA) is bouncing from offline to online constantly.
Publishing anything to /set/ topic works only if I make few tries to publish the same value. Perhaps it has something to do with often reconnects? Maybe it is also why webUI doesn't show it properly?

Upload your config
Press the "raw" button in the SmartEVSE webserver and upload the json settings file, so we can look at your configuration.

To Reproduce
Steps to reproduce the behavior:

1. Normal
2. Configure MQTT

Expected behavior
I would expect no reconnects on MQTT server. This is the only client that does this. Also I would expect "connected" status in the webUI

Screenshots
See above
settings.json

[dingo35]

You are right, that fix is implemented in v3.7.2, and was tested by the people having the issue.
Im going to try to reproduce this!

[dingo35]

Which MQTT server on which OS are you using?

[stomko11]

Mosquitto as official addon on Home Assistant OS

[dingo35]

Do you have the possibillity to install a standalone mosquitto server on Linux to see if this behaviour persists with your SmartEVSE?

[stomko11]

I should be able to try in docker container on a server, outside of HA. Will try later today and let you know.

[stomko11]

I have tested by installing official docker image of mosquitto, running on unraid server.
Result is the same, this is running for about a minute. What I find strange - as I found out correct settings to allow mqtt connections in to the docker, I have been messing with mqtt setup on evse - changing usernames from none, to anonymous, evsemqtt and as well test1. What I find strange is that after I apply config, instead of just trying with the last entered username onwards, it actually keeps trying with all usernames entered before. As if each "save" on evse started additional instance of mqtt client with its own settings? I have not tried rebooting evse controller.
