ad2usb plugin for Ademco/Honeywell Alarm systems  (Indigo Plugin)

Contributed by: berkinet


This plugin offers management of Ademco/Honeywell and OEM variants of their alarm systems. The NuTech ad2usb or ad2serial interface is required. Indigo can interface dirextly to the ad2usb board, or to either board using the included USB/Serial to IP conversion software.

The plugin allows the creation of one alarm keypad device and an unlimited number of alarm zone devices. The keypad device emulates a real alpha numeric keypad and can be used to arm, disarm and enter any codes that can be entered on a real keypad. Code is also provided for creating a virtual keypad on an Indigo Control Page (Indigo PRO is required).

Zone devices display the state of alarm zones and can be used in triggers to invoke Indigo actions.

Please see the included documentation for more information.
