Well it seems that the HAI unit is the "central processor" - it that is the case it is not the most capable of home automation systems. Not bad but not the best. In more then other brand one home automation system, the HAI would be used as just the security part of the system.
My experience with Luxul has not been good - pricey but average performance.
The talk about a gigabit router AND a 10,000 sq ft "router" - I think they mean 10,000 sq ft WAP (wireless access point). It is not likely that in a home environment you need more then one router. And I really doubt that you can cover 10,000 sq ft.
