I’ve found some code that kind of works… It’s a device handler called “thegilbertchan : Cooper RF9500 (all buttons)”. Using it, the dimmers power the light on/off, but the main button does nothing. And there is no dimming to speak of.
I was also looking into the “ST-Cooper-RF9500-Beast” code, but get error messages upon saving.
Has anyone developed new code for this controller?
