How can I tell if my T11012920 Sub-Gigahertz Environmental Data Logger is working correctly?

[FinnLynn]

To confirm your T11012920 Sub-Gigahertz Environmental Data Logger is operating properly, observe the LED indicators on the device. Upon startup, the blue LED will rapidly flash. After the startup sequence, the LED behavior signifies the device's status. A solid green LED indicates registration. A blinking blue LED provides further diagnostic information: one blink signifies the device is running but not registered; two blinks mean it hasn't started; and four blinks indicate it's not configured. If all LEDs display green after the device has started, this signifies optimal system health, a stable cellular connection with good coverage, and successful communication between at least one sensor and the gateway.
