Setup MQTT in Home Assistant

Tools required to Setup MQTT in Home Assistant

We’ll need access to Home Assistant and a Laptop/Phone/Tablet.

What is a MQTT Broker?

The first part of the installation consist in setting up MQTT in Home Assistant. MQTT is a lightweight solution that allows to allow safe communication between devices. In MQTT we have two parts:

  • A brain or broker: This coordinates communication between devices and keeps track of what is sent/received.
  • Subscribers/Publishers: This devices send and receive messages to/from broker and perform actions ( In our case turn on/off light when you click your phone. )

We will setup now the MQTT Broker in order to communicate with the Intelka Smart Devices. This only needs to be done once. After you can just skip this part of the instructions.

Setup Mosquitto Broker

  1. Type in your web browser “homeassistant.local” or access through the Home Assistant App.
  2. Once you logged in go to Settings -> Add-ons -> Add-on Store.
  3. Search and click on Mosquitto Broker, then click “Install”
  4. Once it’s installed, toggle the options “Start on boot” and “Watchdog”, then click “Start” to run the Mosquitto Broker.

Setup MQTT User in Home Assistant

  1. Type in your web browser “homeassistant.local” or access through the Home Assistant App.
  2. Once you logged in go to Settings -> People -> Add Person.
  3. Type a username (i.e mqtt-user) and then toggle the option “Allow person to login”. (Remember to write down somewhere safe as we will need it later)
  4. This will open a new window where you will now need to type a password. (Remember to write down somewhere safe as we will need it later)
  5. Toggle the switch “Can only login from local network”. (Optional)
  6. Click “Create” in both screens to confirm the user creation.
  7. Go to Settings -> System -> Restart
  8. Wait until Home Assistant reboots so changes take effect.

Link Mosquitto Broker with Home Assistant User

  1. Type in your web browser “homeassistant.local” or access through the Home Assistant App.
  2. Once you logged in go to Settings -> Devices and Services -> Add New Integration.
  3. Search and click on MQTT.
  4. A dialog with the message “We discovered these, want to set them up?” will appear. Click the first instance/option in the list with the logo and text “MQTT”.
  5. A dialog with the message “MQTT Broker via Home Assistant add-on” will appear. Click “Submit”.
  6. A new dialog with the text “Success, Created configuration for Mosquitto broker” will appear. Click “Finish”.
  7. You will be now brought back to the menu Settings -> Devices and Services. Click on Mosquitto Broker – MQTT button “Configure”.
  8. A new page will show up MQTT settings. Click “Re-configure MQTT”.
  9. A pop-up dialog will show the Broker options, here you will have to replace the username and password with the ones we used to setup the User previously, then click “Next”. (Optionally you can change the Default MQTT Port. )
  10. The new dialog will show the MQTT Options, just scroll down and click “Submit”. (For most users the default options should work. Optionally you can update this settings to your specific setup.)
  11. A dialog will show the text “Success, Options successfully changed. Click “Finish”.

You have now completed the MQTT Setup in Home Assistant! Let’s move to the next section.
