Troubleshooting
This page focuses on the TubeWitch issues that show up most often: settings that do not save, pressure data that never appears, pressure status that looks wrong, and TubeWitch app upgrades that appear stuck.
Start with the symptom you see on Garmin, then work through the matching checks in order. Most failures come down to saved sensor IDs, SRAM AXS sensor setup, or a Garmin app state that needs a clean restart.
If sensor IDs or related settings do not stick, fix the save path first before troubleshooting the sensors themselves.
If sensor IDs or other settings are not being saved by the Garmin Connect IQ mobile app, try entering one sensor ID first and saving immediately before entering the second. Garmin's save process can be inconsistent when many settings are changed at once.
Use Garmin Express for the most reliable way to save settings.

If the rest of the setup is correct, the sensor can still connect successfully.
TubeWitch sensor ID fields accept numbers only.
Enter only the numeric five-digit portion of the sensor ID. For HGL15841, enter 15841.
If no pressure is shown after setup, work from the sensor outward before changing other settings.
Messages about sensors using open connections are expected during initial setup and appear once per sensor.
You must acknowledge that message for each sensor before data can be received. If the prompt was missed, reboot the Garmin device to trigger it again.
If another TyreWiz data field is also installed on the Garmin device, it will block TubeWitch from reading the sensors.
Uninstall any other TyreWiz data field, then reboot the Garmin device.
If you are unable to assign a sensor to the front or rear wheel in the SRAM app, enable the Sensor Compatibility mode in the TubeWitch settings under TubeWitch Labs, then reboot the Garmin device.
After confirming the above settings, make sure to fully reboot your Garmin device.
On Edge devices, press and hold the power button until the device shows the option to power off. If the device is frozen, hold the power button for about 10 seconds until it powers off or reboots.
On most Garmin watches with a physical power button, press and hold the power button until the watch powers off, then press the power button again to turn it back on. On Garmin watches without a power button, connect the watch to the charging cable, wait a few moments, then disconnect it to restart it.
Live pressure can appear while the high or low status is still wrong if the sensor itself was configured differently in SRAM AXS.
First, use the SRAM AXS mobile app to assign the Front/Rear position and pressure target for each sensor.
The most common TubeWitch upgrade issue is the Garmin Connect IQ mobile app continuing to show an update even after the data field was already queued or installed.
If upgrading from an earlier version of TubeWitch, the Garmin Connect IQ mobile app may appear stuck on "Updating," or it may queue and update the data field but show that an update is still available.
If this happens, reboot your Garmin device and restart your Garmin mobile apps to allow the update to complete and for any new settings to appear in the TubeWitch Settings.
