Sonoff TH20 Elite Temp and Humidity Switch

This device is an upgraded version of the TH16, built on the ESP32 chipset for faster performance and enhanced stability. It includes a hot-pluggable RJ9 sensor port, compatible with THS01 (temp & humidity), DS18B20 (waterproof temp), and MS01 (soil moisture) sensors (sold separately).

The TH20 Elite is ideal for smart geyser control, electric floor heating, greenhouses, and aquarium systems. It supports 6-month historical data logging, Excel export, and scene automation based on sensor readings. Users can set thresholds to trigger on/off actions or receive alerts when conditions exceed safe limits.
