stromleser.one Home Assistant Integration

Prerequisites

Before starting with this guide, make sure you have completed the Home Assistant Basic Setup. You will need the MQTT credentials (IP address, username, password, and port).

Step 1: Open Settings

Open the app and navigate to Settings. Select Integrations.

Step 2: Choose Home Assistant

Select Home Assistant from the list of available integrations.

Step 3: Select Device

Select your stromleser.one device that you want to connect to Home Assistant.

Step 4: Prepare Credentials

Keep all required credentials ready:

• Home Assistant IP address
• MQTT username
• MQTT password
• MQTT port (default: 1883)

Step 5: Click Next

Click Next to continue with the configuration.

Step 6: Enter Credentials and Connect

Now enter all credentials:

• IP Address: Your Home Assistant IP address
• Username: mqtt-user (or your chosen username)
• Password: Your MQTT password
• Port: 1883 (default MQTT port)

Then click Connect.

Verify Integration

After successful connection, your stromleser.one should automatically appear in Home Assistant:

1. Open Home Assistant
2. Go to Settings → Devices & Services
3. You should find your stromleser.one device under MQTT
4. The measurements will be automatically created as entities

Good to Know

The integration uses MQTT, so all measurements are transmitted to Home Assistant in real-time. You can now use these values in dashboards, automations, and scripts.
