# Home Assistant Integration

### Home Assistant Integration

**Overview**

Our modules offer local, cloud-free control of your HVAC systems. The fastest and most reliable method for Home Assistant integration is via MQTT.

**Prerequisites**

- A running Home Assistant instance.
- Mosquitto MQTT Broker add-on installed and configured.
- ClimateControl module connected to your local Wi-Fi network.

**Step-by-Step Instructions**

**Step 1: Configure the ProtoART Device**

1. Access the ProtoART device's web interface via its local IP address. *(Note: Assigning a static IP in your router is highly recommended).*
2. Navigate to the **MQTT Settings** section.
3. Enter your Mosquitto broker details:
   - Broker IP address
   - Port (typically 1883)
   - Username and Password
4. Save the settings and reboot the module.

**Step 2: Add to Home Assistant**

*Manual Configuration:* If auto-discovery is not enabled on your firmware, define the MQTT entities manually in your `configuration.yaml` file using the specific topics outlined in the user manual.

Open Home Assistant and navigate to **Settings** > **Devices & Services**.

Locate the **MQTT** integration.

Your ClimateControl should appear automatically via MQTT Auto-Discovery. Click **Configure** to add the climate and sensor entities to your dashboard.
