Values and parameters

Values are picked by name

Every sim publishes its data under its own names. SimDeckOS keeps one catalogue of values, such as engine RPM, gear, delta to best, fuel remaining, tyre temperatures, TC and ABS, and looks each one up for whatever game is running. You pick Delta to best once, and it reads correctly in every supported sim.

The mapping is maintained by SimDeckOS and updated for everyone. There is nothing to configure per game.

Parameters

A parameter is one car signal made into a reusable object: its value, its states and its look. TC is a parameter. So are brake bias, fuel and the gear.

Because a parameter is defined once, it can live on several devices at the same time: a Stream Deck key, a dial, the wheel’s LEDs and the dash all show the same TC, and stepping it on one moves all of them. The Parameters page lists them; pick one on the left and shape it on the right.

Putting a value on a key or dial

1. Open Layouts and pick the layout for your device.
2. Right-click a key or dial and choose Change what it shows.
3. Pick a parameter or a value from the list. The search finds it by name.

Each value is drawn in the way that fits it: a delta as a plus-or-minus bar, tyres as four corners, the gear recoloured at the shift point, a lap time as a time with no meaningless bar.

Values from SimHub itself

If you want to wire up something SimDeckOS doesn’t map, turn on Use SimHub telemetry in Settings. Every SimHub property then becomes pickable in the parameter editors. Most people never need it.

Other sims

In a sim SimDeckOS doesn’t read itself, most values still work: each one falls back to SimHub’s own telemetry on its own. Notes for each sim has the details.
