Pro Tip:

If the dongle continues to loop in AP mode, try connecting it to a different Wi-Fi network (e.g., a mobile hotspot) to isolate the issue. If it connects successfully to a different network, the problem is likely with the original home network's configuration.

Possible Causes:

Incorrect Wi-Fi password entered during setup.
Weak Wi-Fi signal strength at the dongle's location.
DHCP server issues on the home network, preventing the dongle from obtaining an IP address.
Corrupted firmware during a previous update attempt.
Cloud service API issues preventing successful registration.
Mobile app software incompatibility with the dongle's firmware.

Safety Warning:

Do not attempt to disassemble or physically modify the EG4 monitoring dongle. Doing so may void the warranty and could create a safety hazard. Protect your account by using a strong, unique password for the EG4 mobile app and cloud service. Enable two-factor authentication if available.

What to Look For:

The EG4 monitoring dongle repeatedly enters AP (Access Point) mode, preventing it from connecting to the home Wi-Fi network and synchronizing data with the cloud. The mobile app displays a continuous request to connect to the dongle's Wi-Fi network (e.g., EG4_SERIAL). Data logging to the cloud service is interrupted. Firmware updates fail to initiate or complete.

How It Works:

The EG4 monitoring dongle acts as a gateway, translating data from the solar inverter and energy storage system (ESS) via Modbus/CAN bus to the cloud. This data includes voltage, current, power, SOC, and fault codes. The dongle's firmware manages Wi-Fi connectivity, DHCP client settings, cloud synchronization via API calls, and over-the-air (OTA) firmware updates. An AP Mode Loop indicates a failure in the Wi-Fi connection or firmware initialization sequence.

Solution:

1

Verify Wi-Fi Credentials: Double-check the Wi-Fi password entered in the EG4 mobile app. Ensure the password is correct and matches the home network's password.
2

Improve Wi-Fi Signal: Move the dongle closer to the Wi-Fi router or consider using a Wi-Fi extender to improve signal strength.
3

Restart Network Equipment: Power cycle the Wi-Fi router and modem. Allow a few minutes for the devices to fully reboot before attempting to reconnect the dongle.
4

Clear App Cache: Clear the EG4 mobile app's cache and data. This will force the app to re-establish a connection with the dongle.
5

Reset Dongle Configuration: Use the app to initiate a Wi-Fi configuration reset on the dongle (if available). Refer to the EG4 user manual for specific instructions.
6

Reinstall the App: Uninstall and reinstall the EG4 mobile app from the app store. Make sure to download the latest version.
7

Check Cloud Service Status: Verify that the EG4 cloud service is operational. Visit the EG4 website or check their social media channels for service outage announcements.

Maintenance Tips:

Regularly update the EG4 mobile app and dongle firmware to the latest versions. Enable automatic updates if available.
Periodically check the Wi-Fi signal strength at the dongle's location using a Wi-Fi analyzer app on a smartphone.
Monitor the cloud synchronization status in the EG4 mobile app to ensure data is being logged correctly.
Review the EG4 documentation for recommended maintenance procedures for the monitoring dongle.
