After the release of 0.55 the Tradfri lights did not work anymore. i had to follow these steps to get it working again:
This wasn’t working for me because I tried it on the exististing virtual env installation. It was recommended to recreate the virtual env.
When I recreate the virtual env with HASS 0.56 within a fresh Raspbian Stretch installation, do I need to follow the mentioned steps to get Tradfri working or does it work “out of the box” again?
