Perhaps you shouldn't. The major difference between the two, as far as I
could see, is in the programming flexibility and capacity. More money: more
flexibility and capacity. I might have started with a smartlinc had it been
available a few years ago when I first got interested in this stuff.
ISY has some features I don't believe you'll find at all in the smartlinc.
1) User-defined variables 2) the ability to base actions on time before or
after sunrise/sunset 3) the ability to "re-use" programs: one program can
call another in the ISY 4) many more conditions available for use in
programming. 5) Full integration with ELK security systems. 6) Downloadable
add-on modules (extra cost) that add capabilities.
A simple example: my ISY at the house in Mexico turns on porch lights based
on "sunset + 15 minutes" rather than simply "at sunset". More complex: The
sprinklers for the plantings there turn on for a frequency and duration
using different programs that I enable/disable based on time of year, and
whether the sprinklers are in front of the house (shaded, cool, eastern
exposure) or the back (very sunny, hot, western exposure).
If you don't feel you'll need those sorts of capabilities then the
smartlinc may well be sufficient. Its manual is on line at smarthome.com,
I'd suggest looking through it to see if it'll meet your needs. It's a heck
of a lot less expensive. You'll find the manual for the 99i/994i series on
line at universal-devices.com.
By the way, the folks at UD have proved to be extremely patient, helpful,
friendly and quite responsive over the contacts I've had with them. For me,
that's been a big plus, as initially I had quite a lot of questions, and a
few years back, there wasn't that much on-line about this stuff. Can't say
one way or the other with the smarthome support folks, as I've never had to
use them, since all I've done is purchase devices there.
Phases: You'll need probably a minimum of two dual-band devices to handle
the phases in the house... depending on how many Insteon devices you plan
to employ. Quite easily handled now, as so many devices include dual-band
capability. Or bridge the phases as Moose mentioned.
