Authentic product, 7-day warranty on manufacturing defects, fast delivery across India.\"\u003e\n\n\u003ch1\u003eSonoff THR320D Elite Smart Temperature and Humidity Monitoring Switch\u003c\/h1\u003e\n\n\u003cp\u003eThe Sonoff THR320D Elite is a WiFi-enabled smart switch with integrated temperature and humidity sensors, designed for real-time environmental monitoring and automated control in residential and commercial applications. HVAC technicians, facility managers, and IoT integrators use this device to maintain precise climate control, trigger automated responses based on environmental thresholds, and remotely monitor conditions from any location. It solves the critical problem of manual climate monitoring and delayed response to temperature and humidity fluctuations, enabling predictive maintenance and energy-efficient automation.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Sonoff THR320D Elite operates as a dual-function device combining a relay-controlled smart switch with real-time environmental sensing capabilities. The device connects to your home or office WiFi network and communicates with the eWeLink cloud platform, allowing you to monitor temperature and humidity readings with 0.1°C accuracy and control connected appliances remotely via smartphone or voice assistants. The integrated DHT22 sensor provides highly accurate environmental data, while the relay supports up to 16A load capacity, making it suitable for controlling air conditioning units, dehumidifiers, heaters, and ventilation systems. The device features a compact wall-mounted design with a local control button for manual override, ensuring functionality even during WiFi outages.\u003c\/p\u003e\n\n\u003cp\u003eWhat distinguishes the THR320D Elite is its dual-threshold automation capability, allowing you to set independent trigger points for temperature and humidity levels. For example, you can configure the device to activate a dehumidifier when humidity exceeds 65% and simultaneously trigger a cooling fan when temperature surpasses 28°C. The device supports both local and cloud-based automation through the eWeLink app, enabling complex conditional logic and integration with other Sonoff devices through scenes and automations. Real-time data logging and historical analytics help identify environmental patterns, optimize energy consumption, and maintain equipment efficiency.\u003c\/p\u003e\n\n\u003ch2\u003eKey

basic electrical knowledge. Turn off power at the circuit breaker before beginning work. The device has three terminals: Live (L), Neutral (N), and Load (Lo). Connect your power supply to the L and N terminals, then connect the appliance you wish to control (air conditioner, heater, dehumidifier) to the Load terminal. Secure the device in a standard 86mm wall switch box and restore power. The device will boot up within 10 seconds, indicated by a brief LED flash.\u003c\/p\u003e\n\n\u003cp\u003eDownload the eWeLink app on your smartphone and create an account if you don't have one. Open the app, tap the plus icon to add a new device, select Sonoff THR320D Elite from the product list, and follow the pairing wizard. You'll be prompted to scan the QR code on the device or enter the device ID manually. Once connected to your WiFi network, the app will display real-time temperature and humidity readings. Configure automation rules by navigating to the device settings: set temperature thresholds (e.g., turn on AC when temperature exceeds 28°C), humidity thresholds (e.g., activate dehumidifier at 65% RH), and choose whether these automations run locally or through the cloud. Test your automation by manually adjusting room temperature or humidity to verify the switch activates correctly.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between local and cloud automation on the THR320D Elite?\u003c\/summary\u003e\n\u003cp\u003eLocal automation runs directly on the device using its internal logic processor, requiring no internet connection and providing instant response times of under 1 second. Cloud automation processes rules through Sonoff servers, enabling more complex conditional logic and cross-device integration but requiring active WiFi connection. For critical applications like server room cooling, use local automation for reliability. For convenience features like guest comfort, cloud automation with notifications works well.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use the THR320D Elite to control multiple appliances simultaneously?\u003c\/summary\u003e\n\u003cp\u003eThe THR320D Elite has a single relay output, so it can directly control only one appliance at a time. However, you can create scenes in the eWeLink app that trigger multiple Sonoff devices based on the temperature and humidity readings from the THR320D Elite. For example, when the THR320D Elite detects temperature above 30°C, a scene can activate both an air conditioner (via another Sonoff switch) and a ventilation fan simultaneously.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat happens to automation if my WiFi connection drops?\u003c\/summary\u003e\n\u003cp\u003eLocal automations continue to function normally since they run on the device's internal processor without requiring internet. Cloud-based automations will pause until WiFi reconnects. The device automatically reconnects to WiFi within 30-60 seconds of network availability. For critical applications, configure all automations as local rules to ensure continuous operation during internet outages.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the THR320D Elite compatible with 3-phase industrial systems?\u003c\/summary\u003e\n\u003cp\u003eNo, the THR320D Elite is designed for single-phase AC systems operating at 100-240V. For industrial 3-phase applications, consult with a qualified electrician about using industrial-grade smart relays. The device's 16A capacity also makes it unsuitable for high-power industrial loads exceeding 3680W.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow accurate are the temperature and humidity readings?\u003c\/summary\u003e\n\u003cp\u003eThe integrated DHT22 sensor provides temperature accuracy of ±0.5°C (displayed as 0.1°C increments) and humidity accuracy of ±3% RH. For applications requiring higher precision, you can pair the device with external industrial-grade sensors connected via additional Sonoff TH10\/TH16 devices with probe sensors, then cross-reference readings in the eWeLink app.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
