1. Data Update Delay:
The device updates data every 900 seconds by default, not in real-time.
It is recommended to receive data at least twice in a stable environment to judge accuracy.
2. Temperature Differences:
The temperature controller may read the liquid temperature near the cooling pipe at the bottom of the fermenter, while the hydrometer reads the middle temperature.
After fermentation starts, the liquid temperature becomes uniform, allowing comparison to determine errors.
