First things first: About two years ago I built my setup using adalight and Boblight. For that I bought the following: https://www.adafruit.com/product/738 as well as an arduino uno. Now I want to revive my setup by using hyperion. I stumbled across the following tutorial: https://hyperion-project.org/threads/diy-amblight-project-guide-hyperion-ws2801-ws2812b-apa102.8/ I basically just used the sketch from the tutorial (see attached). I uploaded it to my Arduino and used the "colorswirl" sketch from adalight to verify that it works (using "Processing"). And it does. So far so good... Now I installed OSMC on my Pi1 as well as Hyperion and all seems well. Of course I create a config using HyperCon (see attached). Now every time I start hyperiond the lights will flash to indicate they can be used (as expected). But then... nothing. For testing, I just used the Hyperion Remote App (iOS). I can see that all commands from the app arrive since hyperion logs it: Code: ... EFFECTENGINE INFO: run effect Green mood blobs on channel 0 BLACKBORDER INFO: threshold set to 0 (0) BLACKBORDER INFO: mode:default EFFECTENGINE INFO: effect finished ... However the LEDs stay off... Currently, I have no idea how to debug this since I get no errors or warnings whatsoever. Hope you guys can help me out.
