telemetry

Use the telemetry show command with an actor selector such as --id or --role hero. It reads location, rotation, velocity, speed in km/h, acceleration, and angular velocity from a single world snapshot so all values come from the same frame.

Use the watch command with --seconds and --hz, for example watch --id 137 --seconds 10 --hz 5. It waits on simulation frames rather than wall-clock sleeps, so it works correctly in both synchronous and asynchronous modes.

Yes. Everything it reads, including location, velocity, acceleration, get_control, and get_wheel_steer_angle, is unchanged on CARLA 0.10.0 (UE5 5.5 and 5.8). It is tested against CARLA 0.9.16 and needs only the Python API, not UE4_ROOT.

Zero or jumpy values usually mean the world is not advancing, such as synchronous mode without ticks, or the actor is idle. Tick the world or run in asynchronous mode; the snapshot-based reads stay frame-consistent either way.

The command refuses ambiguous selections and exits with an error telling you to narrow by color, role, or filter, or to resolve the exact id with the world-data skill and pass --id. This prevents reading telemetry from the wrong actor.
