Shelly Plus H&T - Shelly Cloud — Enhanced with a faster processor, Shelly Plus H&T monitors even the slightest change in the conditions and will help you prevent dryness or mold while maintaining comfortable conditions at the premises.
Shelly Sensors Guide: Humidity and Temperature — Connecting to WiFi and performing other computations causes the internal temperature of the H&T to rise. All electronic devices generate a little bit of heat, so this fact is unavoidable. The small size of the H&T intensifies this challenge. The part of the H&T that takes temperature measurements is close by and confined within the same case that houses the heat-generating components like the CPU. Shelly engineers devised a way to get around the problem by having the device sleep, then quickly take a measurement before the locally-produced heat can skew the measurement.
