A mechanism, with action awareness, incorporating a building automation system (BAS) having an interface screen. A mobile device may be logged by a first user into an app for connecting with the interface screen. A display of the mobile device may show the interface screen that reveals one or more components in a space covered by the BAS. The first user may select a first component of the one or more components in the display and perform a first action on the component. A second user may log into an app with a second or the same mobile device which has a display that reveals the one or more components in the space. The second user may select the first component in the display and see a notification describing one or more actions already performed on the first component before deciding whether to perform an action on it.
