Hello guys i have 10 Yeelight LED Smart Bulb 1S and i have bought remote pilot,
i tryed pair those bulbs and 3 of them working fine! i can turn them on/off by remote pilot, but im not able to pair any others.

I trying hold OFF + M button turning on switch on wall then i realse those buttons, its blinking and searching for connection but its not finnding anything.

I heard that remote pilot is not compatibile with Yeelight LED Smart Bulb 1S but its working for 3 of my bulb! Can u give me any advice?
