A well system includes a local controller communicably coupled to a hydraulic diverter configured to control a well shut-in assembly at a well site operable to shut in a wellbore based on a command from the local controller or to shut in or open the wellbore based on a command from a control panel at or in a vicinity of the well site. The well system includes a remote controller located at a location remote from the local controller and the well site and configured to communicate a wireless signal to the local controller to initiate the command from the local controller. The well system includes the hydraulic diverter fluidly coupled to the well shut-in assembly. The hydraulic diverter is configured to, based on the command from the local controller, control the well shut-in assembly to shut in the wellbore and render the command from the control panel irrelevant.
