well I've been jumping from post to post trying to find the answer as I'm sure its been asked loads of times but i just cannot find a definitive answer. my ru950 uses the 433,92mhz frequency and i also have a dimplex fireplace that has a RF remote control that uses 433,92mhz. from what i understand, i might be able to control this as the frequencies are the same, i read something about codegen but the website link is broken? can anyone tell me what i need to do to work out if basic control is possible?
cheers

Control of your fireplace will depend on the protocol of the codes which control it. The Pronto can only send IR protocol codes, whether by IR or RF.

In theory, if you fireplace used IR protcols and you could get hold of these codes, then the Pronto could control it.

I'm not an expert on this, but I would of thought it highly unlikely that your fireplace manufacturer would use IR code protocol to control the fireplace if it is designed to work solely using RF.

hi,

maybe this tool will help (you may find it somewhere outside Germany):

[Link: reichelt.de]

you can convert a RF signal from your device (if it does not use IR) into an IF signal, which you learn then with the Pronto. Afterwards you switch the learned equipment to RF over and you can use the appropriate equipment without the "pyramids".

This worked for me for an exotic device - the experts should correct me if i understood the question in a wrong way.

hope this helps

cheers

Can anyone else confirm that this works as it could be the answer to a similar problem I am experiencing in that I have a some RF remote powered switches that I have been able to turn off or on using random entries from codegen but not find a matching pair of codes.

Let me explain, the receviers have a button that you use to synchronise with the transmitter, so what you do is press the synch button and then press a button on the remote, from this it works out all the codes that the remote will be using. However I have found that using codegen codes I can send either an off or on and it will synch but unfortunately the recipricle code sequence is not what the device is expecting and therefore will not switch back to the other state.

Therefore if the solution of POWERMIDS works I will be a very happy bunny :)

hi baz,

interesting question - because my old recievers exactly needed this synchronisation - but i just put them aside - long time before i got knowledge about the pyramids

i will try the old recievers with the PYs - but this will take a while - so please be patient :-))))

thanks ageage
but why this type of sender? i have a freind thats got a pair of rf video senders but not the pyramid type, i wonder if these will do the same job?

I have done this with me RF-modyfied RU890. I can control the Philiphs lamp-dimmer that use RF 433,92MHz.
I opened up the original remote and check what kind of chip they used, then I google up the chip on Internet. From the specs of the chip I created the codes to the Pronto-remote.

I'm also using the PowerMid pyramid RF to IR converter.

1) Very cheap.

2) Use it to convert a 433MHz RF signal to IR and learn that RF remote buttons on your pronto.

3) Then use it as a RF to IR extender for your pronto. It's very useful if some audio equipments are hidden behind in a furniture.

thanks Stipus - that was exactly the procedure i used, too.
So - good luck!

Doesn't work for me :(

Just bought a POWERMID XL 433Mhz system.

Tried playing RF transmitter into the POWERMID reciever and using pronto to grab the IR. Got the code sequence but the device just doesn't want to know when I play it out via RF from the pronto.

I also have a set of phillips SBC sockets which I use via RF from the pronto using codes from codegen. So as an experiment I tried capturing the RF from the transmitter from these. The code looked very different from the codegen one and of course it did not work.

Idea anyone? Otherwise I have a set of pyramids for sale :(

i managed to grab the ir codes as produced by a philips ir to rf sender and i then went into the protos settings and changed the device settings to send as RF, and now it can control the fireplace!
thanks guys!!!

No, they won't. If you don't give them a video signal, they won't know what to do. The PwerMid approach is designed to deal with remote control signals, not video (which requires repetition, particular voltages for sync, etc etc WAY different from an IR signal).

Apparently the PowerMid takes the IR and does little to it before sending. Therefore the downstream PowerMid does very little to the RF when converting it to IR. This second thing is the ideal situation for converting an RF command to IR.

Now the only hitch is that the IR output of the PowerMid has to be in a form that the remote can learn. Mistakes were made with the first New Generation Prontos, and perfectly good IR codes could not be learned. If the pulses or whatever in the RF commands are just too way out for the remote to learn, well, then you're stuck with no solution.

Hi Rich,

thats goodnews. I am happy that i could help somebody - even an expert. I learned so many things here - so now the first time to give something back :)

ageage

So are you saying that my RU990 may have problems learning and perhaps I should try an older model RU890 maybe? and then use the codes from that?

hi baz,

i assume that you are still talking about the recievers that need this kind of "synchronisation" before they can be used on the remote control. Still did not find the time to try my old ones - but honestly i assume that this won´t work with any kind of pronto. I managed to work exotic devices - (like Rich did with his fireplace) that use a "simple" communication, based on RF. So the pyramids won´t be useless for you in the future as there will be many kinds of devices that will find their way to your household.... :-)
