Philips HUE


hue is a wireless, app-controlled lighting solution with the so-called bridge as a central element. The bridge is connected to the router and communicates wirelessly with up to 50 LED light sources, which can be dimmed, switched on and off and - depending on the model - be changed in light colour.

Note: Only Philips HUE products are supported by this library.

Basic functionality

With output commands the following functions can be controlled:

  • Turn lamps on and off

Only the Hostname/IP-Address and the User ID are used.

Make sure the Render Smooth option is active.
