Single bike
Keep it manual
For a single bike or wheelset, one active set with Auto mode off is usually sufficient.
Settings guide
Every TubeWitch setting, in the order most riders actually need it
This page is meant to cut through the long list of options. Start with Sensor IDs and Active Sensor Set. Then confirm that TubeWitch connects and shows live pressures before tuning alerts. Most other controls are optional, and the defaults should work well for most riders.
Refer to the Settings Reference page for the full list in Garmin Connect IQ order.
Overview
Multiple bikes
Name sets clearly
Clear set names are easier to distinguish at a glance when using Auto scanning or touch switching.
Small screens
Hide nonessential labels
IDs, set names, and too many decimal places can crowd smaller layouts. Readability matters more than detail.
After changes
Reboot when warned
Unit changes and some recording changes are more reliable after a Garmin reboot.
Active Sensor Set and Sensor Set #1 through #5
Active Sensor Set
Choose which Sensor Set is shown in the Data Field. Manually select the active set or use Auto to scan configured sets every 10s.
Sensor Set Name
Name each bike or wheelset clearly. This name is also shown in Connect IQ stats.
Enabled Sensors
Choose Front, Rear, or both. Use this to avoid empty slots in mixed setups.
Front and Rear Sensor IDs
Enter only the numeric part. IDs are printed on the sensor or shown in the SRAM app as AGG#####.
Front and Rear Notes
Notes are visible only in settings and help label tire or wheel details for later reference.
Unit of Measure Display
Unit of Measure
Choose PSI, kPa, or BAR for pressure display in the data field and related stats.
Decimal Places
Extra precision can make small layouts harder to scan. Limit precision to what remains readable while moving. Auto is recommended.
Show Unit of Measure
Turns the unit label on or off in the field display.
Display and Labels
Display Style Mode
TubeWitch Mode is default. Compatibility Mode uses dynamic sizing and positioning for broader device coverage.
Layout Orientation
Auto, Vertical, or Horizontal layout behavior.
Background Color
Auto, Light, or Dark styling depending on layout and page contrast.
Show Front and Rear Labels
Displays F and R labels in the data field.
Show Sensor IDs and Set Name
Useful during setup and multi-bike use, but these can crowd very small layouts.
Label Delimiter
Controls the separator style used on horizontal layouts.
Touch and Timeout
Touch Data Field
Enables Touch to Switch Sensor Sets, Touch to Disable TubeWitch, and Touch to Rescan after timeout.
Sensor Timeout
Default 15 Minutes - During an activity, TubeWitch times out if no sensors are found. No timeout if an activity is not started.
Auto Switch Scan Delay
Default 60 Seconds - If both sensors disconnect while Active Sensor Set = Auto, TubeWitch waits for this delay before scanning other sets [10s each].
High and Low Pressure Alarms
The defaults should work well for most riders. If alerts need to trigger sooner, later, or stay active longer before resetting, this is the place to tune that behavior.
Audible Alert
Enable or disable alarm tone output.
Pop Up Alert
Enable popup alerts on newer supported devices.
Vibration Alert
Enable vibration alerts on supported watches.
Alarm Trigger Delay
Set how long pressure must remain high or low before the alert triggers.
Alarm Reset Delay
Set how long pressure must be back in range before the alert state clears.
Audible Alarm Tone
Select the tone used when audible alerts are enabled.
Alarm Box and Font Color
Color change remains the fastest visual warning state and is always active when the condition exists.
Activity Recording
Garmin reboot is recommended after recording-setting changes.
- Record Pressure
- Record Pressure Alarm Status
- Record Pressure Stale Data Indicator
- Record Sensor Set Number Used
For post-ride review, the most useful additions are often set number and alarm status alongside raw pressure.
TubeWitch Labs
Multi-Sensor Compatibility Mode is the fallback when sensors cannot connect cleanly or are not assigned to front and rear in the SRAM app.
