The LCD is updated every two seconds giving near-instantaneous readings at the sensor whereas the FilesThruTheAir™ Cloud receives readings recorded at the sample rate and transmitted to the FilesThruTheAir™ Cloud at the transmission rate.
In the case of the WiFi-TH and WiFi-TH+ sensors, the LCD will indicate measurements at 0.5°C and 1%RH resolution, but the FilesThruTheAir™ Cloud will always show a greater resolution. The FilesThruTheAir™ Cloud is where your raw data should be viewed for the highest resolution.
