Try adding this to your configuration.yaml (for Legacy ZWave 1.4)
homeassistant:
customize:
light.inovelli_lzw45_light_strip_level: # change this entity if needed.
supported_features: 177
After adding to your configuration.yaml and restarting your server, the white level slider and the white temperature slider will be force added to your light entity. I didn’t get the temperature slider to work. I am still looking at why the temperature slider isn’t working with this device when using the legacy ZWave 1.4 integration.
