Installation

Home Assistant OS (HAOS)

Step 1: Add Repository

Click Add

Step 2: Install

Click Install, Start, then Show in Sidebar

Manual Add-on Installation (Alternative)

If the buttons above don’t work for you, follow these steps to add the repository and install the add-on manually within Home Assistant:

1. Navigate to Add-ons: Go to Settings > Add-ons in your Home Assistant UI.
2. Add Repository:
   • Click the Add-on Store button (usually bottom right).
   • Click the three dots menu in the top right corner and select Repositories.
   • Paste the following URL into the “Add repository” field:

     https://github.com/ESPresense/hassio-addons

   • Click Add.
   • Close the repository management dialog.
3. Install ESPresense Companion:
   • Refresh the Add-on Store page (you might need to wait a moment or refresh your browser).
   • Search for ESPresense Companion.
   • Click on the ESPresense Companion add-on.
   • Click Install.
   • Once installed, click Start.
   • Optionally, enable Show in sidebar for easy access.

DIY Docker Container

Example docker-compose configuration:

version: '3.7'
services:
  espresense:
    image: espresense/espresense-companion
    ports:
      - 8267:8267
      - 8268:8268
    volumes:
      - ./data/espresense:/config/espresense

Port 8268 is required for firmware updates.

MQTT Setup

ESPresense and ESPresense Companion require MQTT to function. Here’s how to set it up:

Using Home Assistant’s MQTT Addon

1. Install the Mosquitto broker addon from the official add-on store
2. Start the addon
3. ESPresense Companion will automatically use these settings

Using External MQTT Broker

1. Install Mosquitto or your preferred MQTT broker
2. Note your configuration:
   • Host
   • Port (default 1883)
   • Username
   • Password
3. You’ll need these details for the configuration step

MQTT Discovery

• Enable MQTT Discovery (“auto-discovered”) in your MQTT configuration
• If disabled, you’ll need to manually configure MQTT settings in the Companion’s MQTT tab

Node Configuration

After installation, configure your ESPresense nodes by setting maximum distance to zero. To modify the maximum distance, send an MQTT message (in Home Assistant, Settings->MQtt->Configure, “Publish a packet”?) :

key: espresense/rooms/*/max_distance/set
value: 0

This ensures you get all distance readings without filtering.

Next Steps

Once installation is complete:

1. Move on to Configuration to set up your floor plan
2. Place your nodes according to the Node Placement Guide
3. Start tracking your devices!

Troubleshooting Installation

Common Issues:

1. Can’t see the add-on in Home Assistant:

   • Refresh your browser
   • Verify the repository was added successfully
   • Check the add-on store logs

2. MQTT Connection Failed:

   • Verify MQTT broker is running
   • Check credentials are correct
   • Ensure MQTT port (1883) is not blocked

3. Docker Container Won’t Start:

   • Check port 8267 is not in use
   • Verify volume mount permissions
   • Review container logs
