【20A Max & Dry Contact Output】 Support to connect 20A Max high load, dry contact output.
【LCD Screen】Real-time monitoring of temperature and humidity data, the screen refreshed every 5S.
【6-Month Temp & Humi Historical Data by Hours】 Support to review the temp & hum history data by hour, day and month. Past 6-month history data can be exported in .xlsx format and accurate to hour.
【Local Automatic Control】Support LAN control, automatic control is more reliable. You can set 8 automatic control programs for you to save electricity bills and create comfortable surroundings.
【Voice Control and Query】Work with Alexa, Google Assistant, you can query temperature and humidity values by your voice.
Note 1: Each sensor (Si7021, AM2301, and MS01 need RJ11 adapter to fit for TH Elite.
Note 2: The RL560 is the new sensor extension cable with RJ11, it can connect the SONOFF temperature and humidity sensors to extend your device’s distance. Si7021,THS01 , AM2301, DS18B20and MS01 can be extended to 60M, and MS01 soil moisture sensor can be extended to 10M.
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
