I've stopped getting updated power, cadence, or speed readings in my app

0 Power /0 Readings

Make sure the trainer is on. Check that the status light above the power button is on. If Fliiiight turns off on its own, charge the trainer.
Make sure one (1) speed index has been installed.
Use the "Trainer Sensors" troubleshooting tool in the 4iiii app, and check out the general troubleshooting tips for Fliiiight not detecting the wheel. Associated symptoms:
- Fliiiight appears consistently connected, but does not apply any resistance.
Troubleshoot your Bluetooth Connection or ANT+ Connection and check for interference. Associated symptoms:
- Fliiiight misses interval or hill slope changes, but keeps applying consistent resistance.
- The app indicates it is disconnecting and reconnecting.
Make sure the trainer is installed in the correct orientation, with the legs extended towards the front of the bike, and the U-shaped frame around the back. Associated symptoms:
- Persistent, severe wheel-magnet contact.
Contact support for assistance if you continue to experience issues.

Some apps will require you to pair your trainer as the source of your cadence data in a separate step from pairing it as a power source and controllable trainer. Look for the option to pair a cadence sensor in the app's "devices" or "connectivity" menu or equivalent, search for devices and select the Fliiiight trainer. Check the app's support resources for more assistance.
If the cadence value populated previously:
- Follow the general troubleshooting steps for 0 readings.
- Check the app's support resources for more assistance.

Some ERG mode apps choose not to display speed by default, due to its lack of relevance in indoor training.
Apps designed to track outdoor activities may use GPS-based speed. In this case, since you are stationary they should report the speed as zero. Extremely low GPS speeds may also be reported due to minor errors from the GPS. The 4iiii app only displays speed based on GPS.
If the speed value populated previously, or if there is also an issue with your power readings, follow the general troubleshooting steps for 0 readings or check the app's support resources for more assistance.
