stromleser.tasmota Home Assistant Integration

You've purchased a stromleser.tasmota and now want to perfectly integrate it into your Home Assistant? Great idea! In this article, I'll show you step by step how to accomplish this easily.

Prerequisites

Before you start, please make sure that your stromleser.tasmota is already connected to the internet. You need the local IP address of your Home Assistant system.

Finding IP Address

If you don't know the local IP of your Home Assistant, simply install the practical "Local IP" extension from the Home Assistant Store – this way you can find it out quickly. Further documentation

Step 1: Install MQTT Broker​

For your device to communicate with Home Assistant, you need a Mosquitto MQTT Broker.

  4. Click Create

Secure Password

Use a strong password for the MQTT user, as it will be used for device communication.

Now, connect your Stromleser to your MQTT broker in Home Assistant:

  1. Go to Configuration → Configure MQTT again.
  2. Enter the following:
    • Host: local IP address of Home Assistant (which you found via the plugin)
    • Username: mqtt-user
    • Password: your chosen password
  3. Confirm with Save again.

Enter Tasmota MQTT Credentials

Done! Your Stromleser is now connected to Home Assistant. You can now find it clearly under Settings → Devices & Services → Tasmota.

Verify Installation​

After these steps, you can verify that everything is working correctly:

  1. Go to Settings → Devices & Services
  2. You should see the MQTT Integration as "Configured"
  3. The Mosquitto Broker should show as "Running" under Add-ons
  4. Your Tasmota Stromleser should be visible under Settings → Devices & Services → Tasmota
