LED Indicator Status Explained (Firmware V109)
This article explains the LED indicator behavior of the XCADEY Power Meter Spider Gen2 after the firmware V109 update.
If you notice changes in LED patterns, this guide will help you understand all indicator statuses clearly.
Overview
After updating to firmware V109, the LED indicator logic has been updated to improve status clarity during operation.
These changes are normal and do not affect:
Power-on Self-test & Battery Indication
When the device is powered on, the LEDs perform a self-test:
Power-on sequence
LED1 → LED2 → LED3 → LED4
(Sequential flashing for 1 second)
After that, LEDs flash 3 times based on current battery level.

Hi, I recently updated my XPOWER-S Gen 2 to firmware V109 (unit XPOWER-S 26541).
After the update, I noticed that the power meter did not appear to enter sleep mode when the bike was left stationary for several hours. The LED continued to blink intermittently, and the device remained visible and available for connection in the XCADEY Utility app even after being at rest for over an hour.
With firmware V41, the device does enter sleep mode normally and is no longer visible in the app after being idle for an extended period. With V109, I also experienced approximately 10% battery drain over two days while the bike was not being used.
I therefore rolled back to V41. Could you please confirm whether this behavior is expected with V109 or if it may be a firmware issue?
Hello, you can roll back to firmware version 41 and continue using it. We will continue to optimize firmware version 109. Thank you for your support and for using our product.
