With an LCD screen, TH Elite keeps monitoring the temperature and humidity in real-time, once they reach your preset threshold or the device's on/off state changes, you will receive the push notification on the phone. Support to connect 20A Max high load equipment like electric floor heating. You can replace your dry contact outputted traditional thermostat with TH Elite, to control the combi boiler or any other systems controlled by the ordinary switch. TH Elite support to review 6-Month Temp & Humi historical data accurate to the hour. In the smart scene, temperature, humidity, on, off support setting as the trigger, on, off, invert as execute actions. Support adding SONOFF devices to Home Assistant for control and automation through eWeLink add-on. TH Elite turns your traditional thermostat into smart, automates your irrigation system, and gives you an easy way to monitor the temperature and humidity. SONOFF TH Elite supports three kinds of temperature monitor and humidity monitor sensors—THS01 Temp & Humi Sensor, DS18B20 waterproof Temp sensor, and MS01 Soil Moisture Sensor. The sensor connector is upgraded to RJ11, supporting hot-plugging making the connection more stable and reliable. The RL560 sensor extension cable can connect the SONOFF temperature and humidity sensors to extend your device's distance. THS01, DS18B20 can be extended to 60M, and MS01 Soil Moisture Sensor can be extended to 10M. Package Included: 1* Temperature & Humidity sensor 1*instructions You Safety, Our Responsibility 1. Strictly selects UL safety components and RoHS environmental protection materials to design the products.2. The high-grade flame-retardant shell material is used.3. Cut off high voltage generated by a lightning strike or unstable power supply when thundering. Different Sensors for Different Scenes The sensor connector is upgraded to RJ11, supporting hot plugging making the connection more stable and reliable. Dry Contact (volt-free contact) Dry contact output acts as a “switch”, controlling the on/off state of the circuit only but not powering it. Replace your dry contact outputted traditional thermostat with TH, to control the combi boiler or any other systems controlled by the ordinary switch. *The output state of normally open dry contact is consistent with power relay, are not available to be controlled separately now. Reliable Temp & Humi Control TH supports LAN control, Wi-Fi disconnected will not affect the operation of your device. 6-month Temp & Humi History Data Support to review the temp & humi history data by hour, day and month. Past 6-month history data can be exported in .xlsx format and accurate to hour. Timely Notifications TH keeps monitoring the temperature and humidity in real time, once they reach your preset threshold or the device’s on/off state changes, you will receive the Push notification on the phone.
