var url = "http://" + bridgeIP + "/api/" + username + "/lights/" + lightID + "/state";

// JSON body to turn the light ON
var body = '{"on": true,"bri":244}';

// Send PUT request
CF.request(url, "PUT", {"Content-Type": "application/json"}, body, function(status, headers, data) {
if (status == 200) {
CF.log("Light turned on successfully");
} else {
CF.log("Error turning on light: " + status);
}
});

this should turn a bulb on and to full brightness, any thoughts on why it does not?

1. The source code above is not adding necessary request headers such as Content-Length for the Post body. Also maybe a HOST header as well? Not sure if this will be required.

2. No idea what HTTP library you are expecting to use but looks as though you are expecting philips to support the Node JS engine which did not exist during the the lifespan of the Prontos.

FYI, philips does not support request or xmlhttprequest. These calls are done best through a library.

CF.request is not a function and as such will never work. What you are posting looks exactly like a Node JS sample using an HTTP Request.

Please confirm this is for Philips Hue.

If you are using the Philips Http library, you'd need to be doing some things very differently.

Does the above command work through Postman or Bruno? Once you have it working there, you can then look at the headers and body that are being sent and emulate that with a raw socket call in ProntoScript if you choose. Not sure the Philips HttpLibrary will completely do what you need.

Also, please consider editing your title to a more appropriate topic to give us some context?
