Product Information
Sonoff TH Origin — Smart Temperature & Humidity Switch
The Sonoff TH Origin is a smart switch that can connect to external temperature and humidity sensors (sold separately). Based on the sensor readings, it automatically turns connected devices on or off — for example, turning on a heater when the room is cold, or activating a dehumidifier when humidity is high.
It’s the more affordable version of the TH Elite (without the LCD screen), perfect for automation setups where you don’t need to read the display on the device itself.
Key Features:
- Automatic Control: Set rules to turn devices on or off based on temperature or humidity readings.
- Supports Multiple Sensors: Works with Sonoff TH sensors — temperature, humidity, soil moisture, and waterproof temperature probes.
- Remote Monitoring: Check real-time sensor readings and control devices from your phone via eWeLink.
- Up to 16 ALoad: Powerful enough for water heaters, floor heating, and pumps.
- 6-Month History: View past readings in the app.
- Voice Control: Works with Google Assistant and Alexa.
💡 Pro Tip: If you want to see the temperature/humidity on the device itself without opening your phone, go for the TH Elite instead. If you just need the automation and phone monitoring, the TH Origin does the same job at a lower price.
