A first appliance receives from a second controllable appliance a command for causing the first controllable appliance to be placed into a state and, in response, determines a trust level of the second controllable appliance. When it is determined that the second controllable appliance is trustworthy, the first controllable appliance executes the command. When it is determined that the second controllable appliance is untrustworthy, the first controllable appliance ignores the command. Otherwise, the first controllable appliance enters into a state in which the first controllable appliance waits for at least a predetermined period of time for a user to confirm whether or not the first controllable appliance should be caused to execute the command.
