    Yup, using ASP and VB as a middle man.
    Easy enough to convert for regular toggle switches too, just replace the loop with an if/then statement.

    Pretty cool - using jquery/ajax to handle?

    OK, I managed to get this done early last week, just hadn't had the time to clean up the code.

    I looked at examples / board questions of a lot of people, so just a general shout out to everybody that's helping other people out on the web with their questions.

    As far as what I did, I created a virtual device that I set to be ON or OFF, using this as a global variable for my loop script to check if it should keep running.

    Then using jquery mobile (http://jquerymobile.com) I managed to bypass the touch screen issues I had, so thanks to those guys for working so hard to get that nice piece of scripting together.

    What you need:
    - Jquery (.js download from http://jquery.com/)
    - Jquery mobile (download .js and .css from http://jquerymobile.com)

    There are 3 scripts:

    That's it, should work just fine for anybody as long as you have all the IR commands set up in homeseer.

    Just a quick update,
    I am having success, but I'm telling an html file to access an ASP file that then speaks to a script in Homeseer in combination with a virtual device that acts as a global variable, since this seems to be the only way to really do this.

    I'm wondering if I should just move the script to the ASP since I am essentially adding an extra step.

    Another problem I'm running into is that mobile browsers don't like the finger to stay pressed, they give nasty pop-ups asking to save the image etc.

    Once I figure out a bypass to this pesky little problem, I'll upload the code.

    Not sure how you would execute multiple events on the HS server based on the client holding down a button. I would like to know how this is accomplished

    So the one thing I'm not figuring out is how to loop the event while the button is pressed (or how at all) and stop it when released.

    I seem to have to do it by running a script, but I'm having problems passing the variables (I wish you could just log / trace how variables are coming in, rather than to have to guess)

    Additionally, how do I post a variable to a script that's already running, since re-sending a command to the script seems to run a second instance of the script.

    Perhaps I should look at Global Variables?

    Makes sense, based on the Global Cache manual, it'll probably be a combination of an event and a low amount of the repeatcount in the sinal itself.

    Thanks

    I have no first-hand experience, but my opinion would be to use an Event and *maybe* couple it with scripting. My reason for the Event method is because it has the "Do not retrigger for xx seconds" *and* you could enforce a Max/Min amount for volume.

  • Smooth volume - Best with an Event, IR Repeating or ASP loop?

    Hi guys,
    Just a post to get peoples opinions and experiences.
    I'm looking to get smooth volume (and later channel up/down) control on my TV's using an iTach in combination with an HTML/Ajax/ASP web solution (I don't like HS Touch, too buggy), and I've been thinking about a few different methods and wanted to get peoples opinions based on what they experienced.

    So what do people think works best:
    - An event that I call on an onMouseDown, and kill the IR's using an onMouseUp.
    - A Larger repeat count on the IR signal and kill it on the onMouseUp (problem here is, do you set the count to 100 or 25, if you do 25 and you want to make a larger adjustment, you have to press the button again)
    - An asp Do or For loop that runs based on a variable set to True onMouseDown, but False onMouseDown (I foresee problems with properly executing this, don't know why).

    Also, on any sort of loop, do I essentially slow down the repeat of the signal, I'm concerned sending too many commands in a short amount of time, essentially hanging up the system or causing other problems.

    Thanks, I appreciate the input,

    RJ
