DIY Floaty Hydrometer

Legacy integration for logging DIY Floaty Hydrometer fermentation data to Brewfather.

The Floaty Hydrometer is a legacy integration. It is disabled by default and only appears in device settings when previously enabled on your account.

Floaty is treated as a legacy integration in the current beta UI. The section in Settings → Power-ups only appears when Floaty is already enabled on your account.

Current behavior

• If the Floaty section is visible, you can:

  • toggle it on/off,

  • copy the Floaty ID,

  • open (configure webhook),

  • open this page via See instructions.

If Floaty is already enabled

1. Open Settings → Power-ups.

2. Copy the displayed ID.

3. Configure your Floaty sender/app with that ID.

4. Start logging from Floaty.

5. In your batch, go to Fermentation → Devices and attach the Floaty device.

About the Floaty Hydrometer

The Floaty Hydrometer is a DIY floating hydrometer project. It is considered a legacy integration in Brewfather -- the toggle in Settings > Power-ups only appears for accounts that previously had it enabled. New users will not see this option.

Data Logged

The Floaty sends batched readings. Brewfather takes the most recent reading from the batch and stores the following:

Field	Description
Gravity	Specific gravity (SG), converted from the raw value (divided by 1000)
Temperature	Temperature in Celsius

Configuration Options

Per-device offsets can be configured 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

A (configure webhook) link is available when the integration is enabled, allowing optional data forwarding to an external URL.

Logging Interval

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