To help you quickly identify the operational status of your device, we’ve implemented a simple LED color system. Here’s what each LED indicates:

🔵 SIM Status

Red: SIM error or not detected

Blue: SIM connected successfully

🟡 MQTT Status

Red: MQTT connection failed

Yellow: MQTT connected successfully

🟢 Power Status

Red: Power issue detected

Green: Power supply is stable and normal

💡Note: Refer to the image below to locate each LED on your device.
