Control your Prana recuperator directly from Home Assistant over Bluetooth Low Energy.

• Automatic discovery through Home Assistant Bluetooth or manual setup by MAC address
• Fan speed control for the main, intake, and exhaust blowers, including preset modes (auto, auto plus, night, boost)
• Air quality and comfort sensors: indoor/outdoor temperatures, humidity, pressure, CO₂, TVOC, and current speeds
• Device options as entities: mini heating, winter mode, flow lock, display mode, and brightness

Or manually add the repository to HACS:

1. Open HACS → ⋮ → Custom repositories and enter https://github.com/dmamelin/ha_prana_ble with category Integration.
2. After HACS refreshes, search for Prana BLE, install it, and restart Home Assistant when prompted.

Download the source archive and copy the extracted files straight into your Home Assistant custom_components/prana_ble directory. Restart Home Assistant.

1. When the recuperator is in range you will see a suggestion card in Settings → Devices & Services prompting you to add the Prana BLE device—accept it to start the flow.
2. If no suggestion appears, choose Add integration, search for Prana BLE, and follow the manual flow. Enter the BLE MAC address only if Home Assistant did not prefill it—the integration trims the advertised name automatically.
3. Set the maximum speed (default 5) and update interval (default 30 seconds). You can change these later from the integration options.

The protocol is proprietary, and device compatibility is unknown.

• Prana 150, firmware 3.2.18, BLE name: PRNAQaq*, sensors: 3 temperatures, humidity, pressure, CO₂, TVOC
• Prana 150, firmware 3.2.18, BLE name: PRNBYav*, sensors: 3 temperatures, humidity, pressure, CO₂, TVOC

• Ensure the Home Assistant host (or Bluetooth proxy) can maintain a stable BLE connection and that no other app is paired with the recuperator.
• For detailed logging add:

  logger:
    default: info
    logs:
      custom_components.prana_ble: debug

  Restart, reproduce the problem, then review Settings → System → Logs.
