3. WiFi Connection/Pairing
- Ensure your phone's Bluetooth is turned on.
- Connect your phone to your home's 2.4GHz WiFi network. (5GHz networks are not supported).
- Open the Smart Life app. Click the "+" icon in the upper right corner to add a new device.
- On the clock, long press the WiFi button on the side for 3 seconds. You will hear two "DI DI" tones, and the WiFi icon on the screen will start blinking, indicating pairing mode.
- In the app, select "Add Device" or allow it to discover the device. Follow the on-screen prompts to enter your 2.4GHz WiFi account and password.
- Once connected, the clock's time will automatically synchronize with your phone's time, and the WiFi icon will become solid.
Note: If the clock does not connect, ensure your router is broadcasting a 2.4GHz signal and that your phone is connected to it. Some routers may have a "smart connect" or "combined" mode; you may need to disable this to see separate 2.4GHz and 5GHz networks.
Operating Instructions
Time Synchronization
The clock automatically synchronizes its time with the network time once successfully connected to WiFi. This ensures accurate timekeeping without manual adjustments.
Temperature and Humidity Monitoring
The clock displays real-time indoor temperature and humidity. You can monitor these levels remotely via the Smart Life app. The app also allows you to set thresholds and receive alerts if levels exceed or fall below your set parameters, for example, to detect potential fire hazards based on temperature spikes.

Brightness Adjustment
The digital alarm clock offers 5 adjustable brightness levels. To adjust the brightness, tap the [Snooze/Light] button located on the top of the clock. Each tap cycles through the brightness levels, allowing you to select the most comfortable setting for any time of day or night.

Dual Alarm with Snooze
The clock supports two independent alarms. To set or adjust alarms, use the dedicated alarm buttons on the side of the clock. When an alarm rings, tap the top [Snooze/Light] button to activate a 5-minute snooze. Pressing any other button will turn off the alarm.

Maintenance
To maintain your JXJHOVV WiFi Atomic Clock, regularly wipe the display and casing with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the surface. Ensure the clock is placed in a well-ventilated area, away from direct sunlight and extreme temperatures, to prevent overheating and ensure accurate sensor readings.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Clock not connecting to WiFi. | Incorrect WiFi band (5GHz), wrong password, or router settings. | Ensure your phone and clock are connected to a 2.4GHz WiFi network. Verify the password. Check router settings for "smart connect" or combined bands and disable if necessary to see separate 2.4GHz and 5GHz networks. |
| Time is incorrect after WiFi connection. | Initial synchronization issue or temporary network disruption. | Ensure a stable WiFi connection. If the issue persists, try re-pairing the device with the app. |
| Brightness adjustment not working as expected (e.g., no auto-dimming). | Misunderstanding of feature or product limitation. | The clock features 5 manual brightness levels adjustable via the top [Snooze/Light] button. It does not have an automatic dimming feature based on ambient light. |
| Temperature/Humidity readings seem inaccurate. | Placement near heat/cold sources, or sensor obstruction. | Relocate the clock away from direct sunlight, vents, or other sources of extreme temperature/humidity. Allow time for readings to stabilize. |
