I have isy set up to turn on my porch and driveway lights (all on the same insteon switch) I would like to dim my porch lights with out dimming the driveway lights. To do that i was hoping to use some type of smart bulbs on my porch (zwave, hue etc) Is that possible or is there a better idea?

That is certainly possible.  The only hitch might be that the smart bulbs don't remember their brightness/hue values across power cycles, and it might take them a few seconds to a few minutes reconnect with their controller and change to the desired levels.  The smart bulbs that I'm familiar with (Insteon, LiFX and Hue) all return to their previous brightness/hue values with power is cycled, so those should work.  Hue, Z-Wave, LiFX, Insteon, etc., all use different wireless technologies, so put some thought into how close your porch is to your controller, or how robust your mesh/wi-fi coverage is in that area.

Thanks for the info.
