Who wants to learn more about KIB?

[flarider]

Any new learnings from playing with this device? I'm settled for the winter and going to see what I might be able to do with it.

I've looked through the source for the app, and things are fairly straightforward, but as stated, the hosted web server does all the real work...not much good logic in the app. I was able to see how to detect the board and initialize communications with it over the pi serial. I've already built a python program I can send and receive commands from the board so I don't need to run the coach app anymore...that was all pretty easy. If I can figure out the commands, I'll be able to build my own interface and tie this into HomeAssistant and Homekit.

That said, I hooked it up to a ch341a, was able to detect the chip just fine (AT25QF641) and dump it...but it all came out as FF. Just did this tonight, so haven't tried to dig any further. I figure worse case, I can figure out what the onboard xmega microcontoller is up to and reverse engineer...unless someone has already figure out the commands for our Dutch Stars...

Anyway, wanted to post my success so far and see if anyone else had made any progress.

I was looking to see if I could hook Home Assisatant to a DSDP KIB system and have a custom dashboard. Have you figured it out any more?

You can. You will first need a means to read/write to the KIB VBUS. It’s J1850 running at 5V. I use MQTT as in intermediate interface between the VBUS and HA. The rest is standard HA stuff. You may be able to use a voltage divider between the VBUS and the RPi, a transistor, or something like a Arduino Nano (5V).

Thanks for the info. something to start looking into.

Thanks to the information in this thread, and a significant about of information from flyboy013, i have successfully achieved complete bidirectional control over the J1850 vbus in my dutch star. I am actively developing software to serve a web-based user interface that will be available remotely, if desired. Best described as a port of coachproxy, compatible with our multiplex systems. Anybody that already has a logic analyzer, i would love if you would be willing to contribute some data that you have collected, especially since different models and different floorplans have different address mappings.

@DavidL i got your PM, but it won't allow me to reply. Privacy settings perhaps?
