SmartPi does not reconnect to MQTT if the broker restarts

[miguelcostaUI]

Hi enerserve,

I've noticed that the SmartPi reconnects successfully to MQTT if the connection is lost and then restored but if the broker is restarted it will not reconnect until a reboot is done. Running sudo systemctl restart smartpi.service also restores the connection.

I'm using a mosquitto broker and sometimes I have to restart it, to update the broker or update the server where it is running, which makes this a big problem because I have several SmartPis on remote locations and to restore the MQTT connection I have to manually restart each one.

Is there a way to fix this and make SmartPi automatically reconnect to the broker?

Hi miguelcostaUI ,

unfortunately, we cannot understand this.
In our setup and also with customers, they always reconnect.
