AC interference?


I’m coming to ask you a quick question about a project.

I have a wemos D1 mini connected to several leds of type SK6812 (custom pcb, 2x5 matrix, 10 SK6812 on same DIN). Your is working correctly except for one anomaly.
On the power strip where my power supply is connected (LED and wemos) I have a socket connected with a fan (it’s hot at home)
The problem is that when I turn the fan on or off, the LEDs light up by themselves. It seems that there is some disturbance because of the fan.

The question is how to avoid this problem?
Would a 68ohm resistor on the data cable solve the problem?

Thank you! And long life for WLED!
