I think I am ready to move to Control4. I have a Casatunes music system (which I would like to keep), and an OmniPro II system that I have never fully utilized, but have it running for lights, thermostats, some wireless door/windows sensors, etc. I'd love to not have to replace ALL my HAI/Leviton light switches, but I'm open to that if it's the most sensible option. I understand the cost ranges for the C4 system, and I am very willing to pay for installation, setup, ongoing maintenance. But as a (former) DIY, I would really like to be able to make small changes without a service call. My understanding is that this is possible with When/Then. I'm looking for a dealer for whom this makes sense.
