There's already some updates' pushes performed in AutomationController.js, but they're implemented wrong (push requires two arguments, not one).
Generally yes, you need some kind of module which will push updates for you.

Has it been fixed in AutomationController.js, or is the task left for community Module developers?

Well, can anyone answer the last question although it's been a while? :D

I still see the push in AutomationController.js source code with 1 parameter. And when connecting to the websocket nothing comes out. Ever.

It would be very beneficial to know;
- Is the websocket implementation ment to be working as it is pr. the latest version?
- Is the websocket in any way restricted by authentication, and if so, what user type needs to connect. Admin?
- Is the websocket implementation limited to local clients only?

Hi,

@kenavn: source code in AutomationController.js has two parameters now but still does not seem to work.

I'm currently working on a WebSocket client for Java. The connection to the server works and I can send custom message from my Z-Way module to the Java client.

Code: Select all

var message = { msg: 'Hello, World!' };
ws.push("my.custom.event", message);
But I don't get the default messages from AutomationController.js (Ln 84-136), for example:

Code: Select all

ws.push({
    type: "me.z-wave.devices.title_update",
    data: JSON.stringify(device.toJSON())
});
If I change the code as follows, I get the messages:

Code: Select all

ws.push("me.z-wave.devices.title_update", JSON.stringify(device.toJSON()));
Any idea? Is this a Z-Way bug or a client problem? Could anyone ever receive the default messages?

Many thanks for all your help.

Regards,
Patrick

We do in push a JSON_stringify, so in your case it is done twice and a string comes to your client. May be client do not accept objects?

Thanks for your answer!

I have just tried again with the following code in Z-Way:

1.)

Code: Select all

var message = { msg: 'Hello, World!' };
ws.push("my.custom.event", message);
2.)

Code: Select all

ws.push("plain text");
3.)

Code: Select all

ws.push({
		type: "my.custom.event.default",
		data: JSON.stringify(message)
	});
Only 1.) reaches the Java client as JSON string: {"type":"my.custom.event","data":{"msg":"Hello, World!"}}

I have also tested a JavaScript client with the same result. Only the first variant reaches the client.

If you can confirm this, please check my pull request.

Regards,
Patrick

Correct! You are right. I missed the API change.

What's the difference between `ws.push()` and `ws.send()`?

There is no ws.send() ;)
