Field	Description
Gravity	Specific gravity (SG)
Temperature	Current temperature (Celsius or Fahrenheit)

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
