SONOFF THR320D Smart Temperature and Humidity Monitoring Switch

The SONOFF THR320D Smart Temperature and Humidity Monitoring Switch is a next-generation solution designed to bring intelligent climate monitoring and automated control into your smart home or workplace. Combining precision sensors, Wi-Fi connectivity, and powerful load control, the THR320D ensures that your appliances, environment, and energy usage are always optimized for comfort, safety, and efficiency.

【All-in-One Smart Monitoring and Control】

Unlike traditional switches, the SONOFF THR320D doesn’t just turn appliances on and off. It continuously monitors real-time temperature and humidity levels through compatible sensors, giving you live data right from your smartphone via the eWeLink app. You’ll always know the exact conditions in your home, office, greenhouse, or storage area.

But it doesn’t stop at monitoring — the switch can automatically trigger connected devices based on your preset temperature or humidity ranges. For example:

• Turn on a humidifier when humidity drops below your comfort zone.

• Activate a heater when the temperature falls too low.

• Start a fan or dehumidifier when the air becomes too damp.

This intelligent automation ensures your environment always stays within the perfect range, without requiring constant manual adjustments.

【Powerful 20A Load Capacity】

The THR320D is built for heavy-duty performance. With a 20A maximum load capacity, it can safely handle high-powered appliances such as:

• Water heaters

• Pumps

• HVAC systems

• Dehumidifiers and air conditioners

• Industrial fans and heating equipment

Whether for residential or commercial use, you can rely on the THR320D to manage demanding devices with stability and safety.

【Seamless App and Remote Control】

Thanks to its Wi-Fi connectivity, you can control the SONOFF THR320D anytime, anywhere using the eWeLink app. Whether you’re at home, in the office, or traveling abroad, you can:

• Switch appliances on/off remotely.

• Check real-time temperature and humidity readings.

• Create schedules and timers for automatic operation.

• Set up smart scenes linking multiple devices together.

For example, you could create a scene that activates your heater when the temperature falls below 20°C or turns on your ventilation fan when humidity rises above 70%.

【Voice Assistant Compatibility】

The THR320D works seamlessly with Amazon Alexa and Google Home, giving you the convenience of hands-free control. Simply ask your assistant to switch appliances on or off, or integrate climate-related automations into your existing smart ecosystem.

Commands can be as easy as:

• “Alexa, turn on the dehumidifier.”

• “Hey Google, switch off the heater.”

【Energy Efficiency and Safety】

Maintaining the right climate isn’t just about comfort — it’s also about saving energy. By automatically controlling appliances based on precise environmental conditions, the SONOFF THR320D helps prevent unnecessary operation, reducing both energy consumption and electricity bills.

Additionally, its durable design ensures safe operation even with high loads, making it reliable for both household and industrial applications.
