I'm considering buying a wireless security system, like the Abode Systems, which has an internet gateway and cellular backup in case of internet failure. It uses Zigbee protocol or its own proprietary 433MHz protocols for its sensors, but it also supports a lot of the same Z-Wave devices that Indigo supports. Other than cellular backup and not being dependent on my headless Mac Mini not to crash, I'm not sure what other reason I might have to buy this to use with Indigo.
The only conflict I see is with my Kwikset door locks, which don't really need to be part of an alarm system. Other than that, the security system would use motion, doorway, window, and other sensors that I don't currently use with Indigo. I see the security alarm system as a sort of 'overlay' for my Indigo home control system.
Anyone have any thoughts, suggestions (like seeing a psychiatrist) about my idea?
