The Blue LED turns off a few minutes after setup. Is this normal?
Answer: Yes, this is normal.
The blue LED indicates the device's internet connection status. After Wi-Fi setup is completed successfully, the blue LED stays solid when the device is connected to the internet.
The device does not remain connected to the internet continuously because maintaining a constant connection consumes a lot of power. For an outdoor device powered by a 4000 mAh battery, keeping the connection active all the time would significantly reduce battery life.
You may therefore see the blue LED stay on for about 40 seconds and then turn off. After approximately 10 minutes, it will turn on again, and this cycle will repeat. This is expected behavior, not a device fault. It is designed to reduce power consumption and extend the device's battery life.
