A given button will issue an extender command or a direct IR command. While one could disable WiFi in an effort to conserve battery power, once the WiFi is disabled, the extender commands will fail.

One could develop a ProntoScript scheme to send direct IR or extender commands based on a global switch, however, one will need to visit every button in the program and convert the actions to ProntoScript.

Another scheme would simply duplicate the activities to establish a shadow program. The shadow would be more or less identical to the original, but the extenders would not be selected.
