Hi,

I just need a simple way to convert a true or false to 1 or 0 from a payload message .

Any help would be much appreciated
:pray:

Hi @bceyresy,

The below will do it.

msg.payload = Number(msg.payload)

The JSONata way

$number(payload)

Or

msg.payload += 0;
return msg;

Or low code
In a change node you can use the change option

Thanks E1Ccid. Both work well. I have another question,

I have 2 Sources of MQTT data coming in, i need a function that deducts them from each other. The issue is there is a slight delay between messages coming in, so i dont get the output.
