[hai-dev] How much can you do via the protocol?

[Philip A. Prindeville]

So, does the protocol as we've implemented it allow for adding
programming lines?

And can a programming line involving doing an HTTP GET or POST? That
would be really handy to have those happen on triggers...

Oh, and this is semi-off topic... anyone have good programming lines for
sprinklers on relays?

Thanks,

-Philip

No to the first two questions. The hai command-line program has
getprogram and putprogram commands but they just move a data block back
and forth:

hai> help getprogram

Format: getprogram [<filename>]

Displays all programs. Optionally download programs to
file <filename>.

hai> getprogram
0x0001 - 04 00 00 00 0a 00 00 00 00 00 00 00 00 00
0x0002 - 01 00 00 00 00 01 cf 00 13 0c 11 fe 11 01
0x0003 - 06 00 00 00 00 00 00 00 00 01 01 00 00 01

The help list gives an idea of what you can do via the protocol:

For the trigger question, I'd say you have to write a program or script
that polls the panel now and then looking for an event (or program your
own time triggers, or whatever) and run HTTP commands from your program.

You could probably find talk of sprinkler handling at Worthington:

So we lack the ability to "compile" the program down into the "object"
format necessary to use with "putprogram" then...

[Chuck & Nicole Cannon]

Yep. The binary format of the program data isn't documented at all by HAI.
