Ok i'm really starting to like the iRule.
If I go with Insteon dimmer switches and outlets will I still need this: http://www.smarthome.com/2411R/IRLinc-Receiver-IR-to-INSTEON-Converter/p.aspx with the iRule?
If I go with Lutron dimmer siwtches can this: http://www.lutron.com/en-US/Products/Pages/StandAloneControls/Dimmers-Switches/MaestroIRDimmer/Overview.aspx be controlled by iRule?
i'm not very familiar with lutron, but for insteon, the IRlinc would work, but would be the least desirable option for insteon control. the reason being: you're limited to only a handful of commands, you don't get feedback, and ir can be less reliable than network and serial control since there is no physical connection. other, more common options include a smartlinc (2412n), or a plm (2412s or 2413s) controlled by either an isy99 or 994, a global cache device (ip2sl or gc100), or a digi portserver.
