Overview
The SONOFF TH Origin 16A is a Wi-Fi switch that controls high-power appliances while monitoring temperature and humidity on its own LCD screen. Set thresholds in the eWeLink app and you will get a push notification when a reading goes over the limit or the device changes state.
It can turn an ordinary thermostat into a smart device, or automate an irrigation system, and works well for electric floor heating or geysers. The temperature sensor is not included, so choose the probe that suits your application.
