In X10 world you would just say (so to speak) "let there be light in the livingroom", but I have this serial port device that controls air condition device and I have need to "speak" to the serial port: "let there be 19C cold at full fan speed". Thats like 3 different commands at once.

Is this kind of functionality possible in Harmony? Can I develop (can do some VB coding) a plugin that displays needed buttons in Harmony and spits commands out to the serial port? Or am I looking at dead end here?

For multiple commands, you would make
use of Harmony Events.
An Event has a 'trigger' (something to
initiate the event) and one or more
'Actions'. An action is anything you can
do from within the Harmony GUI - such
as X-10 address A1 turn on, or C-bus
address 20:00 set 50%. Note you can
use all available Components in an event
- mix & match X-10 and any/all others.

In your scenario, you'd need a "serial
port component". Harmony would then
send the requested commands to the
ComPort (you'd need to figure out what
to send).

Whilst at present there isn't a "Harmony
Serial Component", I do have the
skeleton of one - a project that was put
on hold some time ago. Happy to revisit
it if there's sufficient interest from
Harmony users.

Alternatively, if you know the commands
/ protocol for your air-conditioning unit, I
can write a component specifically for
you - as a private commission. If that's of
interest, email me and we can discuss it

Hope that helps,
