HTD and HAI programming experience?

[N49atv]

Ok, to start off, I'm waiting for some finalized drawings etc, and lot conformation, but I'm trying to budget in HA and WHA.

I like the features and keypads of the lync 12, and door modules. However I'm trying to add some features that aren't natively supported.

Here is what I want to do,
- I'd like to have whole house intercom, and front door intercom (which works with HTD Lync 12, with door kit).
Issues; Any zones muted, DND, or off will not play front door chime. So you have to leave zones on.
Solution; change button on door intercom/door bell to a zone on hai, send 232 command to turn on all zones at set volume. I can pick which I really care about.

- with little ones in our family and friends, and some special needs dependents I'd like to track exterior door openings. There is no feature in the lync to support this.
Solution; So I was thinking of having HAI send 232 to query zone status of HTD, save file, switch to party mode at set volume on all zones (again can purposely leave some out), then play a line out to a set source on Lync, and play file from HAI 2 way voice modual. then recall last save, and reset zones to previous states.
Issues; burn up detracted source on lync (only 5 available).
Not sure, without 3rd party scripting on server, how to skip DND zones, but turn on muted or off zones.

Possible solution; use HAI 2 way voice with surface speakers/mic from HAI. Then just have OPII send a trigger to mute all zones of HTD.
Issues: more speakers (not as nice looking as recessed ceilings), only 2 speakers (I'm a 2 story + basement, garage etc. Ideally I'd like 1 on each floor, 1 in garage, also one in future shop. HAI only lists 2, 8ohm speakers. Only other solution is to feed another amp with line in signal, and add more speakers.

Any other solutions?

Also when I query all zones on HTD, where would the data be saved? In memory on the HTD? On the SD?

I do have the Lync commands but not sure where to upload, or If I'm allowed (they gave them to me freely)

Thanks

I am not familiar with Link system, but if it can send ASCII strings when the zone changes status, you can keep the state of all zones in HAI. When the bell rings, have it send the 232 command, turn a "doorbell flag" on for 1-2 minutes, and when the flag goes off, send commands to all zones that were not on prior to the bell. The zone status should also not be updated during that time, otherwise it will overwrite the saved states to on.

From what I'm reading it doesn't send commands unless requested. So request, read/save in HAI, change, send ring trigger, wait, reset to what was saved. It just may work. I'll have to get the software and see

In that case it will depend on the kind of request/reply format. There is no parsing in HAI, so if your intercom system sends something like 101011 in the reply for zone status, you'll have to define n! message strings for all possible permutations on n zones, which would not be possible. If it was sending something like Z1ON every time it changed status you'd only need to define 2Xn messages. You may want to consider adding a software controller in the middle to handle the complexity.
