SONOFF THR316D Elite Smart Temperature and Humidity Monitoring Smart Switch

The Sonoff THR316D Elite is a smart switch that helps you control appliances based on temperature and humidity. It supports up to 16 A, making it great for heaters, fans, humidifiers, and other climate devices.

It has built-in NTC temperature and capacitive humidity sensors for accurate real-time data. The switch connects over 2.4 GHz Wi-Fi using an ESP32 chip and works with the eWeLink app, where you can check live readings and energy history.

You can set custom temperature and humidity levels. When those levels are reached, the switch turns connected devices on or off automatically. This helps keep your environment stable and safe—whether for people, pets, or plants.

Smart features include timers, schedules, and inching mode. Even if Wi-Fi goes down, LAN control lets it keep working.

The switch supports voice control with Alexa, Google Assistant, and also works with SmartThings. You can add it to your automation routines for hands-free control.

Compact at just 98 × 54 × 31 mm, the THR316D fits easily into DIN rails or common switch panels. It’s built with a fire-resistant shell and secure terminals for added safety.

Whether you need to manage room temperature, protect sensitive devices, or cut down energy use, the Sonoff THR316D Elite gives you reliable control in a small, smart package.
