Smart Temperature and Humidity Monitoring Switch 20A / THR320D

Introducing the SONOFF THR320D Smart Temperature and Humidity Monitoring Switch—a powerful and versatile device designed to transform your traditional thermostat into a smart system, automate your irrigation setup, and provide real-time monitoring of temperature and humidity levels. With a robust 20A capacity and dry contact output, the THR320D is ideal for managing high-load appliances and systems.

Key Features:

• High Power Capacity: Supports up to 20A, making it suitable for high-load equipment such as electric floor heating systems.

• Dry Contact Output: Features a dry contact (volt-free) output, allowing it to replace traditional thermostats to control devices like combi boilers or other systems managed by standard switches.

• Real-Time Monitoring with LCD Display: Equipped with an LCD screen that refreshes every 5 seconds, providing real-time temperature and humidity data.

• Historical Data Tracking: Stores up to 6 months of temperature and humidity data, viewable by hour, day, or month. Data can be exported in .xlsx format for detailed analysis.

• Automated Control Programs: Supports the creation of up to 8 automatic control programs, enabling devices to operate based on preset temperature and humidity thresholds, thereby enhancing energy efficiency and comfort.

• Voice Control Compatibility: Works seamlessly with Amazon Alexa and Google Assistant, allowing for hands-free control and status queries via voice commands.
