Hi,
I've made good progress with Pronto and json.

One last problem:

I want to change a widget depending on a value change.

var value4 = jsonObj.Devices[4].value;
{ widget("DEV4").setImage(CF.widget(value4, "RECOURCES").getImage(0),0);
return; }

I get the message in the console :

ProntoScript error: Argument is not a string
Offending page script: Tag: 'HOME'
Offending line #190: "{ widget("DEV4").setImage(CF.widget(value4, "RECOURCES").getImage(0),0);"

Where is the issue ?

Regards, Fischi
