I reset mqtt and deleted all topics, but the issue still exist.

Config:

I edited id of device to 0x00xxx00022dxxx

I guerss this is fixed already here: #18021 should be available in 4.3.2.
Maybe @ccutrer can confirm? As the JSON shows a null name, but the errror is somewhat different.

[NikolayKash]

Hi @lsiepel , the new version of binding mentioned fixed the issue.

Thanks!

[NikolayKash]

fixed in 4.3.2

This issue has been mentioned on openHAB Community. There might be relevant details there:

[bit-factor]

out of curiosity, any idea when 4.3.2 will be available?

A date has not yet been decided on. I would assume max 3 weeks.
