RS-485 seems OK but UI is all Zero values!

[pcornill]

I have set up the RPi with a RS-485 to USB FTDI adaptor. I can see the messages like below.
Unfortunately, running le Web interface or API doesn’t work for me. I have the following result!
Did I miss something ? I just run:
./infinitive -httpport=8080 -serial=/dev/ttyUSB0

I am having a similar issue with Bryant Evolution setup. I can see the heat pump temps in the logs but nothing else (no blower RPM etc). With infinitude I can see the data on their serial page so I know the interface is working correctly.

[marcusadolfsson]

Update looks like the code is parsing the air handler and heatpump fine, but not the thermostat.

/api/zone/1/airhandler
{"blowerRPM":1223,"airFlowCFM":908,"elecHeat":false}

/api/zone/1/heatpump
{"coilTemp":99.3125,"outsideTemp":87.6875,"stage":2}

/api/zone/1/config
{"currentTemp":0,"currentHumidity":0,"outdoorTemp":0,"mode":"heat","stage":0,"fanMode":"auto","hold":false,"heatSetpoint":0,"coolSetpoint":0,"rawMode":0}

[marcusadolfsson]

Think I am getting closer. Here is the thermostat responding to the fake SAM, but something is wrong.

Hi, any updates on this issue @marcusadolfsson ?

I just tried to install this and have a similar issue. My screenshot has all 0s like the one that @pcornill shows, except mine does in fact show the blower RPM.

When I look at logs I see the following:

Mar  6 14:46:48 server infinitive[929]: time="2019-03-06T14:46:48-05:00" level=info msg="read frame: 2001 -> 4001: READ     000104"

And then when I try to pull it up the web UI, I see the following:

Looking into this more, seems like this is behavior on a touch thermostat. You have to use a project like infinitude instead and proxy the connection through there, as things like temperature live on the touch thermostat and not the ABCD bus.

[nebulous]

It's entirely possible(and I think probable since touch stats can be made aware of SAMs) that settings can be pulled from a touch stat, but at minimum they live at different - as yet undetermined - registers and would need to be queried because the stat has no need to advertise them to other devices.

[gartz]

Interesting discussion, I'm having the same issue here using the touch thermostat. What intrigues me is that external sensors like the outside temperature is advertised using the BUS to the thermostat, but it's not interpreted by infinitive.

[mattster98]

This code advertises as a SAM though, right? Does that mean that even a SAM wouldn't have access to this data?

[mattster98]

@marcusadolfsson did you ever make any further progress here? I just added a new system and figured I'd try this again and so far am only parsing air handler fan speed. /api/devices returns a blank page which I suspect is a bad sign. Lots of data, but not getting parsed into anything useful.

[ericreich]

Any updates to this....

I am only seeing FAN motor rpm and CFM. So I know I am connected and working correctly. Everything else are zeros for temps etc.. I am guessing infinitive is not aware of this variable speed furnace, tstat, and variable speed condenser? Any help would be great.
