Troubleshooting Guide for Data Logger Offline Issues
Offline Processing Solution for WiFi Data Loggers
Please try to reconfigure the network
1.Currently, only 2.4G network is supported, 5G is not supported.
2. If the signal strength of the selected network is <30, the connection is unstable. Please adjust the router position closer to the data logger.
3. The SSID of the selected router network cannot exceed 30 characters, except ‘space’.
4. WiFi router name and password characters are not supported, :, =a-z, a-z, 0-9 and other characters as the SSID and password of the router.
5. DHCP function should be enabled on the router, otherwise you cannot connect WiFi to the router;.
6. If you have problems searching for signal or connecting to the router, you can try to reboot the router or restore the factory settings.
WIFI Band Identification
PC: You can check whether the network band is 2.4G or 5G by viewing the properties in the Wi-Fi connection details.
Mobile: Some phone models allow you to view the corresponding band by tapping the Wi-Fi details page. If this isn't possible, try using a third-party app to determine it.
P.S.: Every router supports the 2.4G band. You can check the assigned Wi-Fi band in the router's management page.
Signal strength can be checked on the device details page.

Anti-reversal, date logger Offline Handling Plan
It can be preliminarily determined that there is an abnormal connection with the server, and it is recommended to investigate in this direction.
1. Weak signal
2. Network environment abnormal
3. Device Offline
4. Antenna Interference
Troubleshooting Steps
1. Confirm the on-site network layout, and check the signal strength of the connection between the date logger and the router via the web page to ensure a good network environment. It is recommended to maintain a signal strength above 50%; alternatively, replace or extend the antenna to enhance the signal strength.
Confirm whether the client router or access date logger network has implemented security measures, such as IP restrictions for devices,
2. Communicate with the customer, authorize IP, or change the network
3. Check the power supply of the data date logger, ensure that the power supply is normal, and confirm the working status of the data date logger using a multimeter or by checking the light status.
4. Confirm whether the antenna is too close to high-voltage power sources, and try to position the antenna to avoid high-voltage interference.
Try connecting to other hotspots, such as a mobile hotspot, for 30 minutes to see if the platform communication recovers, and use this to make a judgment.
Why does the platform show 'offline' when the onsite installation appears normal?
The Data Logger uploads data every 5 minutes. If you have just completed the installation, please wait patiently for 5-10 minutes. Once the Device uploads the latest data, the platform will show 'online'.
