Is this a problem of tradfri or philips-airpurifier-coap?

[oat1]

philips-airpurifier-coap, makes tradfri component not loading at all.

After uninstalling philips-airpurifier-coap, and installing core-2021.12.2 problem disappears.

But when you install the addon again after, the problem cames back.

[kongo09]

At the moment, this integration is not actively maintained anymore, so don't expect any quick resolution.

But could you still be so kind to post some longer log to show how tradfri is complaining and not loading in the context of this integration here? Anything beyond the original log entry?

[kongo09]

You could also try a slightly modified fork and report back, of that solves your problem:

Thanks for the info,
I tried https://github.com/ronaldt80/philips-airpurifier problem is the same

I cannot post longer logs because tradfir does not load at all when the system starts, so it is just this one line
