NOTIFY: MQTT connection error. Please check your settings in the configuration file "config.ini"

[Thorhax]

I've been at this for 3 hours and still can't get it to resolve... tried so many edits to the config.ini but nothing works. I'm about to throw the computer at a wall....

Here is my log with the --debug flag
Please help

And here is my config.ini

Configuration file for RPi-Reporter-MQTT2HA-Daemon

Source: https://github.com/ironsheep/RPi-Reporter-MQTT2HA-Daemon

Uncomment and adapt all settings as needed.

Some settings can be configured by environment variables.

If an env variable is set, it takes precedence over settings in this file

[Daemon]

Enable or Disable an endless execution loop (Default: true)

enabled = true

This script reports RPi values at a fixed interval in minutes [2-30], [Default: 5]

#interval_in_minutes = 5

This script checks for pending os updates at a fixed internal in hours [2-24], [Default: 4]

#check_updates_in_hours = 4

default domain to use when hostname -f doesn't return a proper fqdn

#fallback_domain = home

[Commands]
#shutdown = /usr/bin/sudo /sbin/shutdown -h now 'shutdown rqst via MQTT'
#reboot = /usr/bin/sudo /sbin/shutdown -r now 'reboot rqst via MQTT'
#restart_service = /usr/bin/sudo systemctl restart isp-rpi-reporter.service

[MQTT]

The hostname or IP address of the MQTT broker to connect to (Default: localhost)

Also read from the MQTT_HOSTNAME environment variable

hostname = localhost

The TCP port the MQTT broker is listening on (Default: 1883)

Also read from the MQTT_PORT environment variable

port = 1883

Maximum period in seconds between ping messages to the broker. (Default: 60)

#keepalive = 60

by default Home Assistant listens to the /homeassistant but it can be changed for a given installation

likewise, by default this script advertises on the same default topic. If you use a different

discovery prefix then specify yours here. [default: homeassistant]

#discovery_prefix = homeassistant

NOTE: The MQTT topic used for this device is constructed as:

{base_topic}/{sensor_name}

The MQTT base topic under which to publish the Raspberry Pi sensor data topics.

base_topic = home/nodes

The MQTT name for this Raspberry Pi as a sensor

#sensor_name = rpi-{hostname}

The MQTT broker authentification credentials (Default: no authentication)

Will also read from MQTT_USERNAME and MQTT_PASSWORD environment variables

#username =
#password =

Enable TLS/SSL on the connection

#tls = false

Path to CA Certificate file to verify host

#tls_ca_cert =

Path to TLS client auth key file

#tls_keyfile =

Path to TLS client auth certificate file

#tls_certfile =

What's the actual setup, you've not setup MQTT settings, unless your MQTT server is on the Pi itself.

[Thorhax]

What's the actual setup, you've not setup MQTT settings, unless your MQTT server is on the Pi itself.

I'm trying to monitor a raspberry pi on my network which is primarily used for pie hole but I also want to see CPU, memory, temperature on the device.

Home assistant is set up in a docker container on my Synology Nas.

[bsimmo]

You need an MQTT broker/server, HA has one that work well.

You then need to provide the details to this python program via the setup. The above diagnostic you gave show none of the MQTT setting have been set.
It has no idea where to send the data, as it has no idea where your MQTT server is, hence an MQTT connection error.

Read the instructions for setup.

[Thorhax]

I see, I understood it as we need to setup MQTT2HA on the raspberry pi as localhost then later Home assistant can connect to it to gather data.
I guess it's the other way around.
So does that mean I have to install Mosquitto on Home Assistant as well because following the documentation isn't clear on this part?
Sorry and Thank you.

[bsimmo]

Yes, fully setup MQTT on HA, just follow their instructions. It's not linked to but is per of https://github.com/ironsheep/RPi-Reporter-MQTT2HA-Daemon?tab=readme-ov-file#prerequisites https://www.home-assistant.io/integrations/mqtt/#setting-up-a-broker You then have an MQTT broker for all of your devices to publish data to if they can use MQTT, be it smart switches, (e.g. using Tasmotta or other Pis sending weather data etc) This python program just runs a script that collects the data from the Pi it is on. It then formats it in a way to 'publish' (aka send) it to your network MQTT server (ala broker). That is all it does. HA does not connect to it in any way the other way around (We can ignore how it 'talks back' to it for the reboot, shutdown part for now, you would need to understand MQTT a bit better.) Hope that helps.
