Class TuneValue

java.lang.Object
frc.spectrumLib.telemetry.TuneValue
public class TuneValue extends Object
A number that can be changed from a dashboard at runtime without redeploying, for tuning gains, speeds and other constants. Only in TuningMode; otherwise it is its default and nothing is published. For a value that should survive a deploy, use a frc.spectrumLib.params param instead.

Backed by AdvantageKit's LoggedNetworkNumber (in 2026 it read SmartDashboard directly), so the value is a logged input: a replayed match sees exactly the values the robot was tuned to at every moment. Published under /Tuning/<name>.
