Thanks Ricardo. It's a great program if you love to customize stuff all on your own. A few things you should know before diving into IRule and spending the money.
If you want IRule to control lighting, HVAC as well as equipment, then it ain't gonna be cheap..
Universal ISY controller - $270
Powerlinc Modem - $80
ITach's for any RS-232 or IR devices - $115 each
iRule Advanced License - $99
iRule Automation Module - $25
This doesn't include the light switches because you have so many choices. I went with Insteon at $50 per switch. Lutron RadioRa is $100 each. The Lutron RS-232 controller is a $350-$450 I think. Had I known any better at the time, I would have went with Lutron. It would have cost me an extra $150 or so. The Insteon products work fine but are not quite ready for the big leagues. There are a few quirks here and there with the switches and the powerlinc modem, which is absolutely essential for lighting control, is well known to break every 18 months or so, for no reason that anyone can think of or figure out. I'm on my second one as we speak. Lutron products cost more but are more stable.
When I was having trouble with IRule customer service a year ago or so, I went and got a quote from a dealer for RTI and Control4. Both were more than iRule and Insteon obviously, but not that much more. Maybe $300-$500 more and that would have included free programming for any equipment changes since everything is cloud based now and they don't have to come to your house.
All that being said, iRule is fun and it is nice being able to go buy a piece of equipment and program it immediately like I did with my Kodi media server, but it's not for everybody. If you want lighting control and you really want to stay away from dealers and are going with iRule, spend the extra and go with Lutron. Also, try to get equipment that is IP controllable so you won't have to buy any $115 iTachs.
