SONOFF TH Origin Smart Temperature and Humidity Monitoring Switch 16A – THR316

The SONOFF THR316 Smart Wi-Fi Temperature & Humidity Monitoring Switch is an advanced smart switch designed for intelligent environmental monitoring and reliable control of high-power electrical appliances . With its powerful 16A rated current and 3500W maximum load , the THR316 can directly control demanding equipment such as electric heaters, air conditioners, water pumps, fans, and industrial machinery . The device works hand-in-hand with SONOFF TH sensor probes , allowing it to continuously monitor real-time temperature and humidity conditions in any environment. Using the free eWeLink app (available for Android and iOS ), users can configure smart scenes that automatically turn devices on or off based on temperature or humidity thresholds — ideal for maintaining optimal climate in greenhouses, server rooms, incubators, and aquariums. The THR316 supports voice control through both Amazon Alexa and Google Assistant , enabling hands-free operation as part of a complete smart home ecosystem. Additional smart features include scheduling, countdown timers, remote on/off control, automation notifications , and historical data tracking of environmental readings. Built with an industrial-grade design and made from fire-resistant PC V0 material , the THR316 includes improved safety protection features to prevent overheating, overload, and short-circuit damage. This makes it equally suitable for residential smart home setups , commercial farms and greenhouses , industrial server rooms , and automation projects that require both reliability and intelligent control. The inline smart switch form factor allows installation directly into existing electrical lines, offering a quick upgrade to any wired appliance, transforming it into a smart, monitored, and automated device.
