You can control a resource by sending supported command requests to its connected control device. Depending on the actuators installed in the physical system — relays, motors, valves, and similar components — supported commands might include:
When a dashboard card shows Request sent, Waiting for device, or Offline pending, Realer is telling you that the request was accepted, not that the physical device has already completed it. A resource can remain Available while a command is waiting; the resource status describes whether the resource is usable, while the command row describes the request. You can still request a supported command while the device is temporarily offline or while an earlier command is pending, rejected, or stale; the control may show the requested value so you can see what you asked for. That requested value is not the current state until the device confirms it with the matching request, and a newer Realer request can replace an older open request. If a card says Command unavailable, check the affected command and its control device before trying again.
