BAC0.core.io.IOExceptions.UnknownPropertyError part 2

[pisuke]

Hi Christian,

I'm not sure if I should just return "noUnit" or return EngineeringUnits("noUnits") like I did, so if you can test, that would help me.

Thanks

Thanks for providing a fix in https://github.com/ChristianTremblay/BAC0/issues/352#issuecomment-2597307182

I tried pulling https://github.com/ChristianTremblay/BAC0/commit/84a7e789d11e7ef0b3d0a23ae22d737e62fc219b in my script however now I get this error.

Sorry for leaving it so much time before testing, do you have any comments on what I can change to make it work?

Thank you,

Francesco

When running BAC0 now, you have to deal with asyncio.

One easy way is to start python using

python -m asyncio

and then you can import BAC0 and do your stuff....

For scripts, you can see an example here

Thank you Christian, now I understand about the changes moving to bacpypes3. I'll follow your steps.

In the meantime, I've sorted my issues by forking BAC0 and applying some small patches to the 2023 code, see my changes here: https://github.com/pisuke/BAC0/compare/master...unknown-units-2023 With these changes, I was able to complete BACnet scans in several sites where we have "bad" devices.
