4. Betjening
Once connected to a compatible SONOFF TH Elite or TH Origin device, the WTS01 sensor will immediately begin detecting and transmitting temperature data. The temperature readings will be displayed on the screen of your TH device (if applicable) and accessible through the eWeLink app on your smartphone or tablet.
The TH Elite/Origin device, in conjunction with the WTS01 sensor, allows you to:
- View temperaturmålinger i realtid.
- Set up automated scenes and smart rules based on temperature thresholds (e.g., turn on a fan if temperature exceeds a certain value).
- Monitor temperature history and trends.
5. Vedligeholdelse
The SONOFF WTS01 sensor is designed for durability and requires minimal maintenance.
- Rensning: If the probe becomes dirty, gently wipe it with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the stainless steel.
- Inspektion: Periodically check the cable and connector for any signs of wear or damage. Ensure the connection to the TH device remains secure.
- Opbevaring: When not in use, store the sensor in a clean, dry place away from extreme temperatures.
