Hi .. you cannot add properties to `msg.payload` if initially it was a different type.  
(in this case boolean)

define it as an object .. and tag on as many properties you like 😉

```auto
 setTimeout(function () {

        msg.payload = {} // empty object

        if (state && onZN.indexOf(i) == -1) {
            msg.payload.zone = i
            msg.payload.state = 0
   

        } else {
            msg.payload.zone = i
            msg.payload.state = 1
      
        }

```
