I want to construct a conditional IF/THEN/ELSE macro around the power status of a component that doesn't have a discrete POWER STATUS query command.

So I'm wondering if it's possible to use an existing status query as a "proxy," where a response indicates the power-on state, and a failure to respond (indicating a power-off state) would result in execution of the ELSE argument.

Example:

IF [PIP status] Pioneer 151FD returns [PIP OFF]
THEN
     ....macro for the power-on state
ELSE
     ....macro for the power-off state

Or would the failure to receive any response (from the powered-off component) simply result in an error that terminates the whole macro?

Great question!

that should only take a min or two to test.

Please let us know your results.

Will do.

I just thought someone might know how the IF function responds to a "non-response" and save me the trouble of testing. ;)

the nevo must receive a response.   i had tried this using a computer to see if I could query the power state of the PC (using eventghost)   If the PC was off, I didnt get a reply (since eventghost wasnt running) and the Nevo would not perform the macro.

Yeah, that's what it looks like. :( Thanks for the reply.

I'm just now exploring another approach using certain ERROR responses......I'll report back if anything fruitful develops.

You may have more luck using Widgets.

You could try count the incoming (output from device) charachters. If there are none then that would mean it was off.

What do you think?

Aren't we then way beyond the capabilities of an IF statement? You may well be right, but I was hoping to find a way to quickly ascertain the power status of a display panel within the context of some setup macros. (Without resorting to a bunch of extra Xantech gear.....) I thought that a non-response, if handled in some predictable, usable way by the remote, might offer that possibility.

It may be that there's just no simple solution when the panel can't respond to any query from the STANDBY state.

If that is all you need, than why not use the video sensor (nevo one)?

Stick it in the video out, if the TV is on then the sensor will detect the load.

There's no video out.

As a side note, I haven't completely lost hope on the "no-response-as-a-condition" idea. I was playing with it earlier tonight and it actually worked! ...sporadically. I'm going to see if adjusting the command timing might result in a reliable solution.

No video out, wow, whats the world comming too?

You can also use the digital coax out (most tvs only have optical though)

Nice work on the no reply test.

I have also used with great success trickle star, [Link: tricklestar.com], I use the TV saver.

You connect the TV as the load and the secondary you put a 12v psu. Here in Australia that would cost you less than $80 and works every time. Much cheaper

Infact it has been so usefull that I sent Nevo the info to make an app note.
App note 26 to be exact.

That looks like a pretty efficient solution. I'll certainly consider it if my current efforts fail.

At this point, I'm kind of on a mission to see if there's a way to resolve this with just Nevo programming and hardware. I have Nevo video and voltage sensors, but I'm not using them here because Pioneer plasmas just don't seem to have an "out" that'll trigger either of them. There's an optical out, an IR repeater, L/R/Sub audio outs, something called "Control Out" (for which I've never seen any documentation), and the speaker terminals. That's it.
------

I'm really perplexed right now as to why my "experimental" IF macro is working at all, albeit unreliably. Here's what I'm sending to the TV in its standby state (I used PIP cause it's always off):

IF [PIP status] Pioneer 151FD returns [PIP OFF]
⇒THEN
.....Beep
⇒ELSE
.....Send [POWER ON] to Pioneer 151FD

With the TV in standby, it's not sending a response (I tested for that), so that should just halt the macro. And indeed, the first time I hit this button, I get nothing, exactly as you'd expect. But the 2nd or 3rd time, the TV powers on.

Any thoughts??? If I understood what's happening, I could hopefully use it in a more effective way.

Well I would have thought that "nothing" is clasified as not a match so the macro would run.

I have sent an email to Nevo to clarify. I will let you know what they say.

Thanks. I'll be curious to hear what they have to say.

That was the hope behind this whole endeavor, BTW- that a non-response would simply prompt execution of the ELSE argument.

 that is what I was hoping for when I was interfacing with the PC.  I wanted to query Eventghost to ask if the PC was turned on.  If the PC was off, I was hoping that the Nevo would perform the Else statement, which would have been the power toggle command to turn it on.  It just doesnt want to work that way.  

I ended having to open up the PC and put in a voltage sensor on a couple wires that were feeding 5 volts to the display for the IR controller when the PC was turned on.

Hi,

Reply from Nevo:
~~~
It will not do anything. When NevoConnect expects an answer but doesn’t get anything, you’ll see a red exclamation mark and the IF/Then command isn’t processed any further.
~~~

So is this what you are experiencing?

I still think that widgets would be best. There should be nothing hard using it.
