Hey,
I'm currently working on my own hoval gateway for TTE-WEZ. (https://github.com/abichinger/esp_canbus) and I'm trying to figure out how hoval puts the can ID together.
According to your code
def build_arbitration_id(message_id, priority, device_type, device_id): return (message_id << 24) | (priority << 16) | (device_type << 8) | device_id
the device_id should be: can_id & 0xFF and the device_type should be (can_id >> 8) & 0xFF.
device_id
can_id & 0xFF
device_type
(can_id >> 8) & 0xFF
I found three can IDs on my bus and after sending some SET_REQUESTS from the control modules, I was able to assign the devices.
0x1FE09001
0x90
0x01
0x1FE00801
0x08
0x1FC00FFF
0x0F
0xFF
I would expect both control modules to have the same device_type. Have I made a mistake or is the can ID composed differently?
Devices listed on the GUI of my control module with device IDs:
