Description
The SONOFF TH Elite THR320D is a Wi-Fi smart switch that monitors temperature and humidity and switches loads of up to 20A. A built-in LCD screen shows real-time readings that update every 5 seconds, and an extra dry contact output lets it control boilers, HVAC systems, industrial relays and other non-voltage input equipment.
Create up to 8 smart programs based on temperature, humidity and time, keep 6 months of exportable history in the eWeLink app, and control connected appliances by voice with Amazon Alexa or Google Assistant. It suits heaters, exhaust fans, humidifiers, greenhouses, aquariums and HVAC equipment.
Note: readings come from a SONOFF RJ9 sensor (THS01, WTS01 or MS01) plugged into the switch. You can order the THR320D alone or bundled with one of these sensors.
