New version of software disables old app interface

[dragonflight]

I assume you are using the "old" app interface. Be aware that with software release >4.05 (mine was updated just after Christmas)
the old app protocol stopped. I had to downgrade my software to 4.05.

You might want to look at [nebulous/infinitude] for a similar project in perl.

I did see somewhere (sorry I don't remember where) someone had hacked the new interface. They (carrier) have the ability to charge for individual keys and usage so it may not last.

Sorry for the delay, @dragonflight. I had put this on a pause and I might be looking into it again.

Thanks for that information. I might be on a different thermostat as my firmware version is 14.02 and it hasn't changed in a very long while. What is the model number of your thermostat?

I'm somewhat familiar with the infinitude project. The reason I'm working on this is to learn Python (the whole solution is in Python, including the proxy) and to learn about add-ons and integrations in Home Assistant. It's been fun to look into those things.

I completely understand projects that get started and then stalled for whatever reason - I have tens of projects (may have hit a hundred as I have been ill for 3 years but...)

My thermostat is a SYSTBBECC01-B. The only key number is the -B, yours is either no dash or -A. The newest model is -C.
According to the MANIFEST message the newest software version for yours is indeed 14.02 and given it hasn't changed in a long time, it will probably remain so.

Are you still able to download the carrier/bryant app on your phone, they say they have removed it (if you ever used it)
I suspect the major difference in our versions is mine supports the new "greenspeed" (variable speed) heat pumps and it has a PIR sensor built into the thermostat to detect occupied/unoccupied (though I can't imagine it actually working)

Doing a project to learn a new language is always a great idea - I have learned (and forgotten) so many languages over the years..., but I always fall back to C (which was the 8th or 9th excluding assembly languages!). In fact I rewrote infinitude in C to put it into a PicoW this summer.

Yep, mine is a -A version.

Infinitude in C sounds interesting. Were you able to get it to work? Were you looking to get the serial communication working or the network one (or both)?

[dragonflight]

I have the network (i.e. the messages) working and testing on a desktop. It splits the messages into format (and names) and data to be able to save the changing data in RAM and the format name in the nvram (only once) in preparation to be ported to the PicoW. I have a Microchip micro-powered device (hand wired) that implements a USB interface to the RS-485 (ABCD). bus (read/write) (also written in C). And just for fun I have another rs-232 to USB converter that is attached to a protoboard (a couple of resistors and a comparator) that I built 3 years ago when I first got the unit and it is still running monitoring the ABCD bus.
