- Local Time: Displays the current time.
- Water Temperature: Shows the real-time temperature from the floating pool thermometer.
- Indoor Temperature: Displays the ambient temperature at the Indoor Monitor's location.
- Indoor Humidity: Shows the relative humidity at the Indoor Monitor's location.
- Indoor Monitor's Battery Level: Indicates the remaining battery life of the Indoor Monitor.
- Pool Thermometer's Battery Level: Indicates the remaining battery life of the floating unit.
- Highest Water Temp (MAX): Shows the maximum water temperature recorded.
- Lowest Water Temp (MIN): Shows the minimum water temperature recorded.

5.2 Switching Temperature Units (C°/F°)
To switch between Celsius (°C) and Fahrenheit (°F) temperature units, locate the dedicated button on the Indoor Monitor (refer to the device's physical buttons, usually labeled "C/F" or similar). Press this button to toggle the display units.
5.3 Multi-Thermometer Support
The Indoor Monitor is capable of displaying temperature readings from up to three separate INKBIRD pool thermometers. This is useful for monitoring multiple bodies of water (e.g., pool, hot tub, fish pond) from a single indoor unit.
