I am not sure if Yeelight have any plan for physical button to release?
Something like MiHome button but connected through WiFI.
Thus we can bypass MiHome Zigbee button.
Single click: Toggle light/scene
Double click: Switch between designated brightness, eg. 1%, 25%, 50%, 75%, 100%
Long press: Customizable, eg. music mode, or switch between saved scene
Although we have voice control through Google Assistant and Amazon Alexa but sometime we need to be quite especially at night, button comes in more convenient.
Yeelight can give it a thought, i will support it if you release one.
