This error is coming from the device and one could only guess that this device/firmware doesn't like the way this library is using the did in the requests. At the moment, this is used to store a simplified name, but perhaps this device requires a real did of the device?

You could try to use raw_command command of the tool with a payload you see in your debug logs, but replacing the did part with the real device id. You can find that id in the debug output of protocol responses, there's a field called device_id which has it as a hex-encoded string:

device_id = unhexlify('02f2abba')

For the raw payload, you want to convert this to an integer, for example using python:

python -c 'print(int("02f2abba", 16))'
49458106

Let me know if that helps!

I change all the did to real device id and it works, but when I run each property separately it can run without changing the did. I also use API to get single property from the device without did and it also works. However, if I get more than one property without changing the 'did' it just failed and say that I need 'did' .I'm confused.

Yeah, that's a firmware bug. Let's keep this issue open, we need to add some type of quirk handling for such cases, likely by passing the real did for listed models.

Thank you so much!
