Use this integration to receive Brewbrain Float readings in Brewfather and attach them to active batches.

**Documentation for setting up the Brewbrain integration:** <https://my.brewbrain.nl/docs/integrations>

## Setup in Brewfather

1. Open **Settings → Power-ups**.
2. Enable **Brewbrain Float Hydrometer**.
3. Copy the generated **ID**.
4. Configure your Float/Brewbrain side to send using that ID.

When enabled, Brewfather also shows a **(configure webhook)** link for this integration.

## Attach the device to a batch

1. Start logging on the Float side.
2. Open your batch.
3. Go to the **Fermentation** tab.
4. Open **Devices** and attach the Float device.

## Notes

* The integration is Premium-gated in the current app flow.
* The integration page in Settings links back to this documentation via **See instructions**.

## Data Logged

The Brewbrain Float sends data in SenML format. Brewfather extracts and stores the following fields:

| Field           | Description                                 |
| --------------- | ------------------------------------------- |
| **Gravity**     | Specific gravity (SG)                       |
| **Temperature** | Current temperature (Celsius or Fahrenheit) |
| **Battery**     | Battery voltage (V)                         |
| **RSSI**        | WiFi signal strength (dBm)                  |

## Configuration Options

After your Float device has sent its first reading and appears in the device list, you can configure per-device offsets by clicking the device name in your batch under **Fermentation > Devices**:

* **Gravity Offset** -- Adjusts all gravity readings by a fixed amount
* **Temp Offset** -- Adjusts all temperature readings by a fixed amount

## Logging Interval

**Never log more than once every 15 minutes.** Requests logged more often than that will be ignored.
