1. Before Use – Read First
• This device works with the Smart Life app for remote alerts, on/off
control, and custom sensor settings.
• Supports 2.4 GHz Wi-Fi only (not compatible with 5 GHz). Works
with iOS/Android.
• Place the sensor where the Wi-Fi signal is strong to avoid
disconnections or failed uploads.
• If your router uses a combined 2.4G/5G network, temporarily split
the bands to complete pairing.
• Strict router settings (firewall, AP isolation, etc.) may block
connection. Adjust if needed or consult your router provider.
• If your router has reached its device limit, disconnect another
device or use a different router.

6.2 Sensor Settings
When this feature is enabled, you can set a
normal temperature range.
If the sensor’s temperature rises above the
maximum value or drops below the minimum
value, an alarm will be triggered.
This anti-false-alarm feature prevents
unnecessary freezer alerts by notifying you 1–10
minutes after the temperature exceeds the set
range—helping avoid false alarms when opening
the refrigerator door briefly.
Set how long the device will sound an alarm,
adjustable from 1-10 minutes.
If the temperature remains abnormal, you can
set a repeat interval of 1–12 hours to ensure you
don’t miss important alerts.
Enable or disable app notifications for
temperature alerts.
Turn the device’s audible alarm ON or OFF.

8. Troubleshooting
Q:When does the temperature become accurate? What is the accuracy?
A: After the sensor is powered on, it may take 15–20 minutes for the temperature reading to
stabilize and reflect the actual environment.
The accuracy is ±0.9°F / ±0.5°C.
Q: What should I do if the device cannot connect to Wi-Fi?
A: ① This sensor supports 2.4 GHz Wi-Fi only.
② Ensure the sensor is within the Wi-Fi coverage area. The recommended distance is within
10–15 meters from the router.
③ Reduce potential signal obstacles such as metal doors, multiple walls, or thick walls, which
may weaken the connection.
