Platform support
Edge and watch support
TubeWitch supports Garmin Edge devices and Garmin watches, including vibration alerts where supported.
Feature overview
TubeWitch features for display, alert timing, sensor control, and ride data
TubeWitch supports Edge devices and watches, multiple sensor sets, configurable display modes, detailed alarm controls, timeout handling, and activity review through Garmin Connect IQ stats, with alert timing controls designed to reduce nuisance duplicate alarms.
TubeWitch is the most flexible option for showing compatible tire pressure sensor data on Garmin, with broad control over labels, colors, layout behavior, alarm types, timing, and compatibility settings.
Feature summary
Sensor management
Up to five sensor sets
Store up to five named bikes or wheelsets, with front, rear, or both sensors enabled per set.
Touch controls
Touch Data Field actions
On touchscreen devices, Touch Data Field combines set switching, TubeWitch disable, manual rescan after timeout, and stopping alarm repeats.
Ride review
Connect IQ stats
Average pressures and the active sensor set name are saved to Garmin Connect IQ stats after the ride.
TubeWitch gives more display and alert control than any other tire pressure sensor data field option: colors, labels, layout orientation, background style, alarm outputs, trigger timing, reset timing, decimal precision, and compatibility behavior can all be tuned to suit the users preferences.
Multiple sensor sets and switching sets
Enter the numeric sensor ID, such as 21760, in its Front or Rear slot in TubeWitch. Do not enter a Bluetooth address or BLE device name. TubeWitch receives SKS AIRSPY ANT+ pressure broadcasts using the configured numeric IDs; no Garmin sensor pairing is required.
Named sensor sets
- Store up to five named sensor sets for bikes or wheelsets.
- Enable front, rear, or both sensors per set.
- Save numeric sensor IDs and low/high pressure targets for each wheel.
Active Sensor Set and Auto Switch
Manual mode keeps one configured set active. Auto Switch cycles through each configured set for 10 seconds until an active set is found.
Auto Switch Scan Delay
Default 60 seconds. If both sensors disconnect while Active Sensor Set is Auto, TubeWitch waits for this delay before scanning other sets again at 10 seconds each.
Touch Data Field
Optional on touchscreen devices. The setting combines Touch to Switch Sensor Sets, Touch to Disable TubeWitch, Touch to Rescan after timeout, and Touch to Stop Alarm Repeats.
Display and layout options
Display Style
Display Style offers TubeWitch Mode and Compatibility Mode. TubeWitch Mode is the default, but it may be unavailable on some devices that are not yet fully supported. Compatibility Mode uses dynamic font sizing and positioning and works across all devices.
Display Layout Orientation
Choose Auto, Vertical, or Horizontal layout orientation.
Background Color
Choose Auto, Dark, or Light background styling for clearer contrast.
Label Delimiter
Customize the separator used in horizontal label layouts.
Decimal Places
Choose Auto, 0, 1, or 2 decimal places depending on layout size and readability.
Units and precision
TubeWitch supports PSI, BAR, and kPa. BAR and kPa layouts support decimal precision.
Alarm settings and setup guidance
Set low and high pressure targets for each wheel in each Sensor Set in TubeWitch settings, not in the manufacturer's app. A target of 0 disables that individual pressure limit. Choose units before entering targets; changing units does not convert saved target numbers.
High and Low Pressure Alarm groups keep alert behavior separated for more granular control.
Granular pressure alarm groups
High and Low Pressure Alarm groups organize alert settings independently for more detailed tuning.
Alert outputs
Popup alerts, audible alerts, and vibration alerts are available where device support exists.
Timing and appearance
Alarm Trigger Delay, Alarm Reset Delay, additional repeats 90 seconds apart, tone selection, and alarm box and font color control how alerts behave and appear.
Setup messages
Setup checks confirm that numeric sensor IDs and pressure targets are saved, and identify missing-sensor conditions.
Timeout, stale data, and rescan behavior
Sensor Timeout
Default 15 minutes. During an activity, timeout minutes can be configured. If sensors are not found, TubeWitch stops scanning to save battery and shows a clear "Sensor(s) Not Found" message.
No timeout is applied before an activity starts.
Stale and timeout markers
"?" indicates stale data while reconnect is in progress. "X" indicates the timeout was reached and TubeWitch stopped searching for that sensor to save battery.
Manual rescan
After timeout, scanning can be restarted with Touch Data Field on supported devices or by using Stop and Resume on the activity.
Ever stop for a quick lunch but want to check your tire pressures before you get going again? Instead of just showing "--" on your Garmin Edge or watch screen while your sensors are inactive or out of range, TubeWitch keeps the last known pressures and shows a "?" while it waits for fresh pressure broadcasts.
Activity recording and Garmin Connect IQ stats
- Record pressure from the active sensor set.
- Record pressure alarm status.
- Record stale and timeout indicator status.
- Record the sensor set number used in the activity.
- Average pressures and the sensor set name appear in Garmin Connect IQ stats.
