The Pronto can send RF signals and can a reciver recieve it and decode if so yes how do i decode the codes send by pronto

Can all this be done without the RF Extender.

Search for posts by Dave Houston in this and the classic pronto forum for more info.

Yes, it's possible, the problem is the frequency :
The US prontos (TSUxxxx) use 418MHz
The European Prontos (RUxxx) use 433,92MHz

You cannot change this frequency, except if you change a chip in the remote (which is quite hard work).

So your equipment must have the same freguency as your remote.
In Europe e.g. there's X10, Intertechno, and some others, who use this frequency.

In Europe, Infrared extender (IR to RF to IR) like the Powermid (pyramid shape), or a video transmitter (which sends back IR) use 433,92MHz

So you can use the (RF to IR) part to convert the RF from your RF remote, into IR learned by the Pronto.
Then you just need to enable RF on your Pronto for that page, and voila :-)

You often have to keep pressed the button of the RF remote while learning, and set the duration on the pronto to 0,3s or more.

But even if all harware has the same frequency, doesn't mean it'll work :
Some RF to IR converters won't be able to transcode correctly the orders, or some RF remotes use a special coding which can't be converted by the RF to IR converter...
Yes, you CAN learn RF with a RU950/RU980 :-)

It's been done using the method decribed by wheely30k and previously by Dave Houston

Just out of curiosity, does anyone know WHY there are no RF learning remotes out there? I take it that it is an FCC thing, but am curious about it. I guess it could be a security risk with learning garage door openers and such, but in the same time, it would be really nice to be able to at least have the ability to program RF hex codes into a remote, so you can use it with your own equipment!

e.g. There are many light switches and thermostats... even adjustable beds that work on RF frequencies that the Pronto (or any other universal remote) will not be able to control.

Any thoughts?

Dave Houston said a long time ago that it had to do with the frequencies. Each frequency has to be licensed so a RF learning remote would have to have thousands of licenses to cover all the frequencies. It would be cost prohibitive.

I'm just going from memory and paraphrasing quite a bit but I believe that is the just of what the response was.

Hi,

I've been searching the forum for RF learning and this topic was spot on.

I live in Europe(Sweden) and have a RU990 and a Logitech Harmony Ultimate.
I have a pair of powermid extenders.

I am extremely interested in if it really works making either one of the remotes learning RF this way??cause all my lightning at home is from Nexa and they have a self learning system which involves 67 million different codes...

But how am I supposed to do this?? should I take the original remote next to the receiving pyramid and my pronto, harmony next to the transmitting pyramid??and then put remote in learning and pressing the command??

Cause I believe I have tried this before and never gotten it to work...but I could try it again...

First, it might not work for the reasons given in Post 3.

Second, see if you have an IR sensor on hand. The camera on a cell phone will often see IR as white, so point an audio/video remote at your cell phone's camera and see if the IR shows up. That helps you see what's happening here.

When it works, it's like this:
The PowerMid has two parts. As it's designed, one part senses a factory remote's IR (of audio components, for instance) and transmits RF. The second part receives the PowerMid's RF and converts it to IR. We're going to use this backwards.

Set up the second part to receive the RF from the RF remote that you want to replicate with the Pronto. Check with your cell phone camera to see if the camera sees IR when you push the button on your RF remote. If you do, then this just might work. If you don't, it still might work.

Put the Pronto where it will see IR from the PowerMid. Push an RF button while the Pronto is in the learn mode. If the Pronto learns a command, try it out to see if the Pronto now controls your RF device.

After researching this, I tried this a few years ago. I still have the PowerMid that would not work using this method....
A good answer is easier with a clear question giving the make and model of everything.

Hi Ernie :)

Well if you are referring to the different freq thats not a problem.

Yes doing it backwards, so far I'm with you, but do I need both pyramids or just the RF2IR ??

When you say point the camera towards the remote do you mean the RF remote??why would it emitt an IR??

I have tried setting it up, unfortunatly my pronto is dead so I'm waiting for new batteries and I'm trying to setup the harmony, but it doesn't get any IR signals...

I have tried the pyramids and they work so its not them...

I've read in some post that Dave said you have to have the right distances and really have to put a distance between the RF remote and the Pyramid, how big a distance are we talking??

Will the Ipad 4 camera suffice??
Cause I say nothing when pressing the RF remote...and nothing is emitting from either one of the pyramids...
