If you use the lifx component, download the latest version, rename it as lifxtest.py custom component in the appropriate directory (i.e. .homeassistant/custom_components/light/lifxtest.py) and then add: light: - platform: lifxtest to your configuration.yaml This not only fixed the lifx componen…

Looks like it might be fixed in 0.42.3 anyway… https://github.com/home-assistant/home-assistant/issues/6985
