Hi, I have been working with morcibacsi on building a library to add our own DIY devices on the VAN network, the library is fully functional but needs some understanding on the VAN protocol and discovering the signatures of the devices you want to talk to.
Feel free to use it on your projects:

Quite a few very interesting projects in your repositories. Especially ESP32 parking sensor decoder and reverse engineering key algorithm from disassembled firmware.

Unfortunately, seems as such topics don't catch much attention here on the forum.

Regards
