Node Red - contrib-mid-devices

So i’ve got node-red running and got a simple automation for turning a light on and off at a certain time…

i’ve moved on to my xiaomi buttons to turn some lamps on and off but i’m so very very lost…

i’ve installed node-red-contrib-mi-devices and i think i’ve set up the right bits… but really i’ve no clue…

All i want is that if i click the button, it toggles the yeelight bulb on or off…
