IKEA Tradfri aiocoap.credentials.CredentialsMissingError: No suitable credentials for

njbuch · November 17, 2018, 4:23pm

I struggled a lot with getting the IKEA Tradfri devices to be working with HA. Took some time to get the modules installed correctly. But now I am at the place where this one kicks in:

Did you figure this out? I am getting the same error

njbuch · February 7, 2019, 8:59pm

No, and I am really eager to get my pytradfri up and running, I have been dreaming about this for 6 months now. But I am still hoping, I have a feeling that its soon.

Squashyware · February 7, 2019, 11:17pm

I got mine going today!
I reset my gateway but I am not 100% sure that was needed. Here is what I did, not neccesarily in this order but this should prevent going back on yourself like I did!

I am not sure the first 3 steps were required:

From Tradfri App, removed all devices.
Hard reset gateway. (I think I did this 3 times as all the devices came back the first)
Reinstalled lubuntu! (I dont think this was necessary. Probably removing the virtual environment would have been enough.
Updated and Installed dependencies:

apt-get install python3 python3-pip python3-venv
apt-get install build-essential libssl-dev libffi-dev python3-dev
apt-get install autoconf

Installed to virtual environment following instructions here: Manual Install

Fingers crossed.

Due to missing autoconf I did that after the hass install then manually installed the erroring components:

pip3 install pytradfri[async]==6.0.1

Hope this helps you.

njbuch · February 10, 2019, 9:45pm

Hmm, interesting that you made it work, did you have exactly the same error message? Can someone with more experience maybe assist in pinpointing where we should look for the problem, it seems that this could be fixed with checking some versions of libraries or dependencies?

Squashyware · February 10, 2019, 10:19pm

If you don’t fancy a full rebuild just try these:

apt-get install build-essential libssl-dev libffi-dev python3-dev
apt-get install autoconf

Maybe uninstall home assistant before this one:

pip3 install pytradfri[async]==6.0.1

And watch for error messages on the home assistant reinstall.

Squashyware · February 10, 2019, 11:20pm

Also here was my error message in the logs.
It was different on the ha install.

If this works, I am guessing that there is something wrong elsewhere, with dependencies or libraries?

Squashyware · February 11, 2019, 4:45pm

I definitely missed off some of those installs the first time.
Give it a go. Uninstall HA from the virtual environment, install dependencies through apt-get, then do the pytradfri specifying the version before installing HA again.

njbuch · February 11, 2019, 7:09pm

You were completely right. It worked with a re-install. Thanks buddy!

njbuch · March 7, 2019, 8:40pm

Argh, the problem came back with the 0.89 upgrade.

And I re-tried the trick, with no success!

njbuch · March 18, 2019, 7:29pm

I am still messing with this, and trying to be constructive, what might be the problem? It seems so simple, and when it worked the first time, it has to be a version incompatibility? Any hints?
