MQTT port 1883 in use

[kueblc]

Your first two solutions may work, the third may not, given that the Tuya device expects to connect to a broker on a specific port.

I think that ideally, we should detect that a broker is already running and use that, rather than stopping and starting a new instance of mosquitto. I suppose this may bring about some new issues if the broker is password protected.

In the meantime, you could comment out these two lines in start_flash.sh:

sudo service mosquitto stop >/dev/null 2>&1
$screen_with_log smarthack-mqtt.log -S smarthack-mqtt -m -d mosquitto -v

Thank you @kueblc - will comment the lines out and let it use my existing broker, which isn't password protected.

Along these lines what happens if you have a different computer running mosquito broker, is that going to interfere with this process?

It shouldn't interfere

Can this be closed?

[ragenhe]

Yes sir! I got it!

@merlinschumacher Perhaps we can open a new issue tagged as a feature request regarding automatic MQTT broker conflict resolution. I have some ideas, if you'd like help, or to assign the issue to me.
