Brightness can be controlled using a weather station. Weather stations usually measure brightness via 2 sensors. The sensitive 'dusk' sensor usually measures brightness from 0-1000 lux. The less sensitive sensor measures brightness from 0-100000 lux. Brightness tweak combines those two variables into one single variable.

Example instructions:

• In the example replace the Brightness - dusk and Brightness - day variables with the weather station group addresses to receive correct data and use the Brightness variable in the configuration as a single value node.
