The Sonoff TH Elite THR316D is a Wi-Fi smart switch designed to monitor temperature and humidity while controlling electrical devices. It features a built-in LCD screen that allows you to check real-time environmental data at a glance, and it supports a variety of compatible sensors like the THS01 or DS18B20 to ensure accurate readings. With a current rating of 16A and an input voltage range of 100-240V, this device can handle a wide array of appliances, making it useful for automating heaters, humidifiers, or ventilation systems. Managed through the eWeLink app, the switch lets you set specific thresholds to trigger automated actions or receive push notifications when conditions change. You can also integrate it into your smart home using Amazon Alexa, Google Assistant, or SmartThings for voice-controlled management. The white plastic housing is fire-retardant for added safety and measures 98 x 54 mm, fitting easily into most setups when installed at a height of less than 2 meters.
