[pascalbcnn]

My Home Assistant is not able to open Zigbee2mqtt. I´ve setted it up yesterday and it worked fine. Today i wanted to add an device and now its not starting anymore. Does anyone has an idea why?

Thats the information out of the protocol.

[chris-1243]

You have two times device_options. Remove the second and it should be fine.

Check line 42 and line 47. I would remove lines 47, 48

[pascalbcnn]

okay, thanks. I´ll deleted it and now i restart home assistant.

How can that be happend? I did not change anything in there or added something.

[pascalbcnn]

Thanks for your help! It´s now working again. :)
