ERROR: AttributeError: 'TridonicDALIUSBNoResponse' object has no attribute 'value'

[Hadatko]

Hello i am starting to use this code to control my dali devices. I am getting this error (even the devices are found on bus) which looks like some error in python code? ERROR: AttributeError: 'TridonicDALIUSBNoResponse' object has no attribute 'value'

[sde1000]

We will at least need a stack trace to look at this problem.

[Hadatko]

Sure, i will try provide as much information as i can. Do you have some doc related to debugging? Or any suggestion how to provide usefull data? (sorry i just started so didn't go trough it deeply)

[sde1000]

You're going to have to say what you are trying to do and how you are trying to do it. Describe your hardware and software setup. What operating system are you using? What version of Python? When it doesn't work as you expect, what does it do instead and what does it show on the console?

[Hadatko]

Ok so this deeply :D

I want use https://github.com/dgomes/dali2mqtt project which is using your module. I connected this https://svitimprotebe.cz/eshop/dali-usb/ tridonic usb dali converter to my server and connected to it one dali device. Then i created docker container and i am trying to run mentioned project and i am getting errors which looks are related to your module.

You should open this issue in the dali2mqtt project — it looks like there's an issue with the way it deals with "no response" being returned by the driver.

[Hadatko]

Understand. Thank you.

[dgomes]

Well this is an issue that could better solved in python-dali

We have a base class for the driver, but errors, each driver has their own classes... we should have a common base class.

Else daemons would need to account every single error object per driver.

[rnixx]

@dgomes I agree. The driver code needs consolidation, see https://github.com/sde1000/python-dali/issues/69. I hope I soon have some time again to contribute.

[Hadatko]

Guys i am just amazed that you all are still active and quick to respond ;)
