Please make sure you have
autoconf installed (
$ sudo apt-get install autoconf) if you want to use this integration. 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.
