Re: [node-red] need help with array - msg.payload : undefined

[Colin Law]

You have

var array_status_base2 =
{payload:(context.global.wBetriebsStatus_01.toString(2)).split("")};
var heiz = {payload:array_status_base2[15]};

array_status_base2 is an object not an array, so
array_status_base2[15] is undefined. so you need something like
var heiz = {payload:array_status_base2.payload[15]};
though I have not analysed your code sufficiently to know whether that
is the only problem.

Note that you can do simple debugging in a function node by doing things like
node.warn( "value is " + array_status_base2.payload[15]});
then that string will appear in the server terminal window or log.
