Hi,

Thank you! It's always good to hear that somebody is finding it useful :-).

The configuration information is typically located in the communal uhppoted.conf file, which by default is expected to be in one of the following location:

Alternatively you can specify a configuration file with the --config command line flag, e.g. ./uhppoted-mqtt run --config myconf.conf --console.

A minimal MQTT conf contains the following information:

# SYSTEM
bind.address = 192.168.1.100:0
broadcast.address = 192.168.1.255:60000
listen.address = 192.168.1.100:60001

# MQTT
mqtt.connection.broker = tcp://localhost:1883
mqtt.connection.client.ID = me
mqtt.connection.username = it
mqtt.connection.password = qwerty
mqtt.security.authentication = NONE
mqtt.security.outgoing.sign = false
mqtt.security.outgoing.encrypt = false

This configures uhppoted-mqtt to connect to the MQTT broker with a simple TCP/IP connection i.e. no TLS, authentication or encryption. To get a complete list of all the configuration options, use the config command:

./uhppoted-mqtt config

A quick way to get a basic working uhppoted.conf file is to use the config command, pipe it to the configuration file and then remove all the unwanted information, e.g.:

./uhppoted-mqtt config > myconf.conf

Hope that gets you started!

NOTE 1: _the message formats are not documented as yet because they are still subject to change - however the Makefile has examples for every supported command_.

NOTE 2: depending on your requirements, it may be worth taking a look at the node-red-contrib-uhppoted project. The NodeRED base library includes nodes to communicate with an MQTT broker so wiring up a UHPPOTED controller to an MQTT broker is relatively straightforward.

Hi,

I've added a working example for uhppoted-mqtt using Docker and it includes the configuration for a TLS connection to the MQTT broker.

Am going to close this - feel free to reopen if you have any further questions.
