After having to reset my Tradfri gateway (I wasn’t able to connect both my remote and a lightstrip at the same time) HASS can’t connect to my Gateway anymore. The log shows an error related to the encryption.

Somebody knows how to reset the tradfri component or knows what else to do?
I’m running Hass.io with latest HASS version on a raspberry pi 3
removed it… reboot… added key and result…none

just did it
that file never showed again on my config folder…
I have a weird I that can be read as 1 that I might have insisted more than once… but log shows an error not really related to wrong key…
and by the way… was working few days back
as far as I’m aware aiocoap is the part of pytradfri that handles the encryption. but your error is different from the one I got anyway.
There’s some issues concerning the tradfri open on github, I suppose those get fixed within the next weeks.
I added the IKEA component in configuration.yaml file besides having Discovery enabled. And now it shows up twice in the “Configurator” pane on the overview page(?)

I’m not sure it is a bug, but it seems that it cannot write the tradfri.conf file.
it looks more like the pre shared key for the encryption is an empty string.
and the .tradfri_conf is hidden, might wanna try ls -a in a console in your configuration folder
honestly…to me… and I am having exactly same problem… looks like UI is not sending the typed string to the core. That is why lot of people does not have issues… and others (like and you) have. We deleted the tradfri.conf where they key was… and not we cannot add that key?
