I'm glad I came back to check the post. I didn't realize there were more responses. Evidently I didn't click on the email link to allow more notifications to be sent.
I'm curious about the EZ Automation offerings, so I gave them a call today. Right away, they said I should call their sister company, AVG.net. Both companies offered solutions that would use the same RIO communication as the PV1200. The difference is that EZ Automation offered more of a do-it-yourself solution, that is less "industrial" than AVG. The tech guy at AVG talked about a turnkey solution, or buying a software-on-a-dongle license for about $500. The software is Uticor. It's an interesting solution (maybe not the turnkey, since I'd like to know how to do it, and the cost is pretty high), but I'm bothered by the lack of mention on this board. I'd really like to know if anyone here knows about this company and has experience with them. You can send me a private message if needed.
