Where to start

Review the example sensor configuration and the observations it produces.

Use it in your project

Connect one observation to a bounded behavior and record missing or misleading inputs.

Scope and limitations

Sensor simulation remains an approximation; exact plugin and message interfaces depend on the installed release.
