I can change payload type run time. Payload type always is "str" when i open properties again. 😂

You are setting it to string on initialisation.

Remove the `type:"str"` restart node-red, refresh browser, try it again.

I tried, the same result 😂 It always show "str" type.

```auto
$("#node-input-payload").typedInput({               
        types:["str","num","bool"],
        typeField: "#node-input-payload-type"
});

```

It is OK when i add ( payloadtype: {value: 'num' } ) for payloadtype 🤩 🤩

```auto
defaults: {
            name: { value:"" },           
            pin: { value:"", required:true, validate:RED.validators.number() },                      
            read: { value:false },
            user: { value:false },
            payload: { value: 1, validate: RED.validators.typedInput('payloadtype')},
            payloadtype: {value: 'num' },
            edge: { value:1, required:true}
},

```

js , 💥_change node.payload to node.payloadtype selected data type !_  
`var payload1 = RED.util.evaluateNodeProperty(node.payload, node.payloadtype, node);`

Ah yes, I missed the fact you hadn't added the variable into the default object. That too is important. Note, you can set it to str in the default if you wish, the important part is that the variable is declared.
