How to add ewelink bulbs properties into function node?

Hi, I’m following this tutorial to create dimmable actions using aqara button, but I’m just stuck with the function node at the moment.

I’m not quite sure how to import the properties from the sonoff bulbs into the function node. This is what I’m getting from the developer tools

The function node that I’m trying to edit

update variables

flow.set('yeelight1_on',msg.payload.state.on);
flow.set('yeelight1_bri',msg.payload.state.bri);
flow.set('yeelight1_colormode',msg.payload.state.colormode);
flow.set('yeelight1_ct',msg.payload.state.ct);
flow.set('yeelight1_hex',msg.payload.state.hex);
flow.set('yeelight1_hue',msg.payload.state.hue);
flow.set('yeelight1_sat',msg.payload.state.sat);

smart dimming

var x = flow.get('yeelight1_bri')

if(x <= 125){ 
    msg.payload = x; 
    return[msg,null]; 
} 
if(x > 125){
    msg.payload = x;
    return[null,msg];
}
