A: To maximize battery life, the sensor sends a "Heartbeat" update every few minutes. However, if there is a Sudden Change (e.g., +0.6°C or +6% humidity), it will trigger an Immediate Alert and update the app instantly to ensure your safety.Q: Can I use this in my refrigerator or freezer? A: While it can measure low temperatures, the metal walls of a fridge act as a "Faraday Cage," which often blocks the WiFi signal. For the best results, place the sensor in open air within range of your router.Q: How do I know if the battery is low? A: The Tuya app provides a clear battery percentage indicator and will send a notification to your phone when it’s time for a replacement, so you’re never left unmonitored.
