The Sonoff THR320 smart switch is a powerful 20 A Wi‑Fi relay for precise temperature and humidity monitoring and automatic appliance control. It offers remote control in the eWeLink app, support for temperature, humidity, and soil moisture sensors, timers and schedules, integration with Amazon Alexa, Google Assistant, Home Assistant and IFTTT, plus a LAN mode for reliable operation.

The Sonoff THR320 reliably handles demanding high‑load applications such as underfloor heating, indoor pools, terrariums, greenhouses, or irrigation systems. With the RJ9 4P4C connector you can attach compatible sensors and set automatic actions based on current temperature and humidity.

In the eWeLink app you can turn the device on/off from anywhere, create timers, schedules, and up to 8 programs for efficient operation. LAN mode keeps control even during temporary internet outages. Notifications alert you when thresholds are reached, and clear charts show data history by hour, day, and month, with the option to export 6‑month history to XLSX.

The thoughtful design includes a large control button, easy DIN‑rail mounting, a safety shield, and improved wiring against short circuits. The housing made of flame‑retardant PC V0 meets UL and RoHS standards, ensuring safe operation even in adverse weather.
