hm - maybe u got the problem. I tried to controll the fans separatly. 1st was no problem, on off instantly, no issues. 2nd - half of the leds turned off, rest of the colours persist. After that - tried to turn 3-6 off in a row - nothing happened, effect was stuck. took about 1 min til they tunred off. now 2-6 flicker again 😄 well thats weird. so do u think this means 2nd-6th are not working? or its just the 2 causing the problems? gonna disconnect the 2nd of the node and try controlling them separatly again.
