IKEA TRÅDFRI can be auto-discovered by Home Assistant. If an instance was found, it will be shown as “Discovered”, which you can select to set it up right away.

Incorrect security key
Fatal DTLS error: code 20 might indicate a missing or incorrect security key. Pay close attention as e.g., “I” and “l” can easily be confused.
After updating your IKEA Trådfri Gateway firmware it might be necessary to repeat the configuration process. One error you might experience after a firmware update is
Fatal DTLS error: code 115. If you encounter problems:
- when configured using the integration: remove the integration through Settings > Integrations > Tradfri > delete (trash can icon)
Then restart Home Assistant. When prompted, enter the security key and click configure, just like during initial setup.
Please make sure you have
autoconf installed (
$ sudo apt-get install autoconf) if you want to use this component. Also, installing some dependencies might take considerable time (more than one hour) on slow devices.
- The TRÅDFRI Shortcut button, Remotes and motion sensor only send information about their battery status, no events, to Home Assistant and thus can’t be used to automate with. If you want to automate with these devices, you need to use something like ZHA.
- The groups you find in the app are not imported into Home Assistant as they are known to cause stability issues. We recommend that you use the native light groups instead.
