Halo ceiling light and smart wireless dimmer


I can’t find the Yeelight Halo ceiling light in the Yeelight app. The same is for the smart wireless dimmer.

I aslo wonder how to change the dimmer’s battery.


Pls switch the power on-off 5 times in 2 seconds/per time to the initial status( more info. prefer to the instruction). the change method of the dimmer‘s battery prefers to the instruction as attachment.

Something is lost in translation. It’s more like, Switch on and off in 2 seconds and do this 5 times
