MQTT Broker Docker Container

Reference: https://hometechhacker.com/mqtt-home-assistant-using-docker-eclipse-mosquitto/

1. Create the folders mkdir -p mosquitto/{log,config,data}

2. Create the mosquitto config then input texts in << >> nano mosquitto/config/mosquitto.conf

<< persistence true persistence_location /mosquitto/data/

user mosquitto

Listen on all interfaces

listener 1883

#Allow connection without authentication allow_anonymous true

log_dest file /mosquitto/log/mosquitto.log log_dest stdout

3. Ctrl+o - Enter, Ctrl+x to save

4. Run the MQTT docker container docker run -itd
   --name=mqtt
   --restart=always
   --net=host
   -v <folder_path>/mosquitto/config:/mosquitto/config
   -v <folder_path>>/mosquitto/data:/mosquitto/data
   -v <folder_path>>/mosquitto/log:/mosquitto/log

Home Assistant Docker Container

Reference: https://www.home-assistant.io/installation/linux#install-home-assistant-container

1. Create the folder mkdir ha

2. Run the Home Assistant docker container docker run -d
   --name homeassistant
   --privileged
   --restart=unless-stopped
   -e TZ=Asia/Manila
   -v <folder_path>/ha:/config

Arduino Pico-W sample code

[email protected]:daniloc/PicoW_HomeAssistant_Starter.git

How to

1. Set up the MQTT broker docker a. Make sure that the mosquitto.conf file is set Note: Error occurs when Adding user name and password, the docker image restarts always. Use without credentials.
2. Test the MQTT broker a. Can use the Linux terminal as mosquitto-client b. Subscribe to a topic mosquitto_sub -h -t c. Test publish to a topic mosquitto_pub -h -t - m
3. Set up the Home Assistant docker a. Add MQTT in the integration section b. Supply the configuration and credentials required for the MQTT broker (i.e. broker ip, port, username, password)
4. Download the Arduino Pico-W project a. Configure the Credentials.h and supply the credentials of the MQTT broker b. Load the project to the pico-w board

Supposedly, the Pico-W board will automatically be added to the Home Assistant dashboard!

How?

• The Home Assistant supports auto discovery. The PicoW creates a discovery message within the firmware and publishes it to the topic that Home Assistant for configuration.
