 * @param {string} name - The name of the virtual device. Spaces in the name are removed to form the device ID.
 * @param {'light' | 'outlet' | 'switch' | 'mounted_switch'} type - The type of the virtual device. Can be 'light', 'outlet', 'switch', or 'mounted_switch'.
 * @param {() => Promise<void>} callback - A callback function that gets executed when the device's on/off state changes to true.
 * @returns {Promise<Endpoint>} A promise that resolves with the created virtual device.
 * @remark The virtual device is created as an instance of `Endpoint` with the `OnOffPlugInUnitDevice` device type.
 * The onOff state always reverts to false when the device is turned on.
