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.

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

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?

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

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.

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.

Pretty cool - using jquery/ajax to handle?

**rjdevries** · April 3, 2012, 05:55 PM

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.

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