X2 LED Indicator Lights
The X2 contains two sets of (4) LEDs visible through the lid of the enclosure. These X2 LED indicator lights give insight into the operation of the data logger and Wi-Fi module, respectively. Two additional green LEDs beneath each magnet port give feedback when the magnet input is triggered. Note that all LED operation is suspended in sleep mode. A magnet can be used to wake the unit up and display its current status.
Data Logger Status LEDs
The main data logger status LEDs are found in the top transparent opening in the X2 faceplate and provide an indication of the power status, connectivity, system function, and more.
The data logger LEDs function as follows:
| LED Color | 1 Second Interval | 3 Second Interval | 5 Second Interval | 3 flashes every 5 seconds | Solid |
| Green | Primary power heartbeat | Secondary power heartbeat | Backup power heartbeat | — | — |
| Blue | — | — | Weak/No cell signal | Strong cell signal | WQDataLIVE integration successful1 |
| Yellow | — | — | Data acquisition in progress | — | Sensor calibration in progress |
| Red | Significant system error2 | — | — | — | — |
1WQData LIVE integration is automatically done after sensor detection is complete
2System errors can result from internal sensors detecting high current, humidity, or pressure. These errors can be indicative of a leak or other major problem with the system that requires attention.

Wi-Fi Status LEDs
The Wi-Fi status LEDs are primarily used to determine whether the device is readily configured as an access point (Blue LED), or is connected to a configured network (Yellow LED). For more information on the operating modes please see X2 Wi-Fi Modes.
The Wi-Fi LEDs function as follows:
| LED Color | 2 second interval | 5 second interval | Solid |
| Green | Wi-Fi module power heartbeat | — | Embedded web communication in progress |
| Blue | Waiting for direct connection | Directly connected to device | — |
| Yellow | Searching for network1 | Connected to network | — |
| Red | Fatal system error | — | — |
1If a Wi-Fi network has been setup on the device and is available, the X2 will automatically connect to the configured network after 30 seconds without a direct connection being established.
