Subscribe to Portal using Web Socket

Javi · January 22, 2019

Is it possible to subscribe to the Portal using REST?

I can send REST commands to ISY from portal with the same Credentials

        String credential = Credentials.basic(mUserName, mPassword);
        mRequest = new Request.Builder()
                .url(baseUrl)
                .header("Authorization", credential)
                .addHeader("Sec-WebSocket-Protocol", "ISYSUB")
                .addHeader("Sec-WebSocket-Version", "13")
                .addHeader("Origin", "com.universal-devices.websockets.isy")
                .build();
        mListener = new IsyWebSocketListener();

I get the following Error:

unexpected end of stream on Connection{my.isy.io:443, proxy=DIRECT hostAddress=my.isy.io/34.237.193.77:443 cipherSuite=TLS_RSA_WITH_AES_128_GCM_SHA256 protocol=http/1.1}

@Javi,

Unfortunately not yet but definitely something important on our requirements list.

With kind regards,
Michel

Thanks Michel,

I will look into soap for portal integration

Javi · January 24, 2019

Does the ISY Portal require headers different from the ISY for event subscription? Is there Portal subscription documentation which may assist me?

I can get SOAP subscription to work on local network but I am having problems connecting to the Portal. The Java Thread below woks with my local network. I have commented out ("//" for java) the lines changed for connection to the Portal. IF (username:password && URL && Port) are changed I get no response from the Portal. IF (username:password && URL) are changed and port left at 80 than I get the following Lines:

LineBuffer: HTTP/1.1 400 BAD_REQUEST
LineBuffer: Content-Length: 0
LineBuffer: Connection: Close

I just noticed I was looking at 2 versions of documentation will try again tomorrow

@Javi,

What URL are you using?

With kind regards,
Michel

Javi · January 24, 2019

Url

URL("https://my.isy.io");

Port

443

Michel Kohanim · January 24, 2019

Thank you. But, that's incorrect. In my.isy.io, click on Select Tools | ISY Information and then copy/paste the URL for your ISY (not the Admin Console).

With kind regards,
Michel

Javi · January 25, 2019

Thanks Michel!

I spent 3 hours trying to get a connection which turned out to be on one line of code that was adding a new line char to the encoded username and password that the ISY accepted but the Portal did not. There are not many great examples for Java connections to the portal. So hopefully the code below will save the next person a few hours.
