I added one of these to control my pool lightning
Everything works fine except that the red and green channels are swapped. When I select red in HA, the test strip (which I use for testing and tried with two different controllers) turns green and vice-versa.
What could be wrong?
Let me think hard… Bad wiring? 
Yeah, that was my first thought but tried with a new, unboxed controller and pins are connected in the exact same way 
Was more thinking on the strip side, really
Go into the magichome pro app and long press on the device and change the sort order from RGB to GRB. You may have to try all 6 options depending on how you have it wired
You nailed it
