  Okay cool.  If anyone with a 2 zoned system wants to try and get this going, I'd love to arrange some remote access to your rPi so I can verify proper behavior of Infinitive.  Send me a DM or email me (address can be found on the github link).

  I'll need to reread the protocol dumps I have to give you a better answer on that.  I'm not familiar with how a two zoned system works.  Do you have two thermostats and two separate HVAC systems all on the same ABCD bus, or does a single thermostat control everything somehow?   The only real...

Yeah sorry about that, a friend noticed that the JSON interface wasn't working so I fixed it.  The x86 release also doesn't work due to endian issues with the CRC-16 library I used initially.  I'll roll a new release soon.    

  I ordered this one: https://www.amazon.com/gp/product/B00O6Q2PKM but it's no longer available.  I see similar adapters on eBay, however.  I think I paid around $9 for it.

I suspect Infinitive (https://github.com/acd/infinitive) may provide some (most?) of what you're looking for.  I've implemented a JSON API for getting/setting basic thermostat parameters.  If folks are interested in a JSON API to manipulate the schedules and such I can probably put that together...

Ah neat.  I assume that's captured by impersonating the Carrier web services rather than snooping the ABCD bus, yeah?  I'd like to identify more of the proprietary data available on the ABCD bus but it's slow going...  

Hi All,   With the help from a kind gentleman on this forum I figured out how to mimic a SAM and write to my thermostat.  I've put together a program that exposes a web interface and JSON API to interact with the system.  I plan to add data logging in the future.  I'm interested to hear if it...

I'm here to followup on a thread regarding automation of a Carrier HVAC system.  Not particularly exciting, but maybe it'll work out...

Haha, I was wondering the same thing.  Here's post 1 of 3... :)

Are az1324 or DevXen still active here?  I'd love to see the details on how to mimic a SAM which were provided and resulted in successful writes in late 2013/early 2014 according to the thread.  In particular I'm trying to understand how to populate the first three bytes of a write to control...
