Let us explain the LEDs a bit better:
- LED lights on both the pedal sensor and the Powerpack represent the state-of-charge of the respective battery inside, going from full green (fully charged), yellow, orange and red (empty). This is a qualitative and visual way of knowing the battery level for both devices. The app (upcoming very soon) shows a more precise measurement.
- The LED on the pedal sensor will always "breathe" (pulse slowly) to show you the state-of-charge regardless of it's condition (connected or not, to anything). When riding, please don't try to look at the LED on the pedal sensor, this battery lasts for months and months, you can check the battery level when at home or parked.
- On the pedal sensor, if you place it logo-side-up on a flat surface you can then tap it to enter a "menu" (teal fast blinking light). For the moment, this only allows you to enter Bluetooth pairing mode, but in the near future you will be able to connect with the app and configure other stuff to your preference.
- If you charge the pedal sensor, the LED goes solid and steady color showing the state-of-charge. Early firmwares of the pedal sensor that we shipped don't behave this way, don't worry, all sensors are fully upgradeable.
- On the Powerpack, if the light is "breathing" (pulsing slowly) it means the Powerpack is not connected to anything. When the light on the Powerpack goes solid (steady color), it is successfully connected to the pedal sensor (or the app in the near future).
- If you quickly want to check the state of charge of the Powerpack you can just press the button once (a simple click) and it will show the color and fade away. This is a great way of knowing quickly if you'll have to re-charge for your next ride or you are ready to go.
- To turn the Powerpack on, press and hold the button for ~1 second. To turn it off, press and hold until you see magenta color and then release. It's not necessary to turn the bike off after using, it will automatically "get bored" and turn off on its own.
- Blue pulsing lights on either component mean they are in Bluetooth pairing mode. To cancel this on the pedal sensor, put it on a flat surface foam-side up. To cancel on the Powerpack, turn it off.
