It is working great! For me personally another great thing would be an option to say hyperion not to send send artnet data if the ambilight function is not turned on because I am normally controlling all my lights with openhab. So I could use the dmx fixtures independently when hyperion is just in "color-mode" to use them in different light scenes as well. The only problem that is a little bit complicated to solve is the issue with the blacklevel recognition because the dmx fixtures are always on even if the screen is black. If I tweak the gamma levels to optimal values the lights are out when the screen is black or dark but the maximum brightness is reduced way too much so you couldn't talk about an "ambilight" anymore. But this is not really artnet related.
