Did you change HA versions as part of the upgrade?

I previously had issues with i l or 1 all looking the same. 0 and O may have the same issue.

did you install autoconf as noted in the docs?

I was behind several version, the new version needed the new python so i upgraded the OS.

In the new OS, im using the lates Homeassistant! Autoconf is already installed. gateway and ubuntu server is on the same router.

So if anyone ever google search find this post…

Follow the install instruction on this link: GitHub - home-assistant-libs/pytradfri: IKEA Trådfri/Tradfri API. Control and observe your lights from Python. Examples available. On pypi. Sans-io.

After all that, if you enter the security key and get error in hass log like this:

[coap] Exception CancelledError() can not be represented as errno, setting -1.

You goofed up the key. The key text font is stupid. L and I are the same.

Hi! I have the same problem, and i have extracted the key from the qr-code, so there can’t be a typo - what can i do?

6

Delete tradfri cache in hass folder, factory reset the gateway.
Also whats the error log?

Thank you for your advice. i am totally new to hass, so i can’t even find the cache in the folder, and i do not know where to find the error log. i am running homeassistant on a mac.
