EventGhost learning and transmitting rf signals

[radeon]

Hello All,

I am relatively new to EventGhost but have started using it for, well, as many tasks as possible to make like a little easier! Basically anywhere i can think of. ´üè (Android client, ir blasters for neon lights, tv, surround sound, optical switcher, virtual audio cables. etc)

One of the great features I have immediately fallen in love with is the IR blasting thanks to stottle and his amazing plugin. (Thanks stottle!! )

My question is, I have some dimmer plugs for the lounge lamps which are controlled by a mini RF remote using the frequency 433.92MHz. Now can anybody help in a method of hardware/software which will enable me to ÔÇ£learnÔÇØ these signals and transmit them from my pc via EventGhost? Not too dissimilar to the ir blasting but obviously using RF signals instead?

Is there any sort of cheap USB adapter that can send/receive RF signals that I can buy to enable me to do this?

Any help would be greatly appreciated!!

Thanks,

John

What kind of rf controlled power plugs do you have?

[radeon]

Hey Buddy. They are some brand called Philex if that helps?!

Cheers, John

Im guesing thats a no then?

holiday here...bb soon

Hi again, sorry for the delayed reply but we had a holiday here

Regarding rf I have some experience from those consumer products like Nexa, Sartano, Proove etc but never heard of your type and I could not find any more info with google either

The key is if your devices are using "known" protocols

- what type of device is it? (self learning or code switch)
- what frequency is it using? (433 MHz)
- do you know any other compatible brand?

A lot about how to integrate rf devices wit home built receivers/transmitters are written here
http://www.eventghost.org/forum/viewtop ... f=9&t=2080

Regarding products to buy, there are many available that will work with EG using existing plugins

- RFXCOM
- X10
- Telldus
- FS20

The question is however if your existing devices are compatible with any of those

Best regards, Walter

Thanks for the reply!

Device wise - i think they learn the signal. once plugged in you have to bress a button on the remote inorder for it to learn the signal.
The devices use 433.92MHz (as it says on the back of the remote itself)


Thanks for the link to your thread, i will have a good look. I noticed you made a receiver out of a pyramid (is the powermid same thing?) receiver. Do you know if i would be able to mod a powermid transmitter to make a transmitter?

FYI, the Philex remote controls are exactly the same as these:

Hi,

Besides the USB rf transmitters (manufacturers mentioned above) you can use a powermid pyramid to send the correct rf signals if you have so called pronto codes for them

You could then use a USB-UIRT IR emitter and send those pronto codes as ir signals. The powermid will "convert" them into rf and your devices/power switches can be controlled

The problem you are facing is however to find the pronto codes that works with your devices

One method is to use NetHome analyser sw (described in the link I posted to you) but you will have to build a receiver (and I recommend you to build a transmitter as well)

With the analyser sw and the receiver, you can record your remote key presses as pronto codes and use them in the transmitter setup in EG (there is a well working NetHome plugin there as well)

So the steps would be:
- download & install NetHome and the Analyser
- build a receiver and a transmitter
- download and install the EG plugin for NetHome

- capture the remote key-presses you need as pronto codes
- paste them into actions you create in EG to be sent to NetHome

When the action is triggered, the pronto code will be sent to NetHome and further transferred to your rf transmitter

So, when everything is done, you will be able to control your devices from EG

Best regards, Walter

PS Currently I do not know any other sw that supports sending pronto codes as rf. As far as I know you need NetHome for this transformation

Hi everyone,

sorry for reviving such an old thread but it was very pertinent to my question and I found it safer as a newcomer to add a question instead of posting a new thread.

I have a home alarm system at home (cheap 315mhz wireless door sensors and base unit, Chinese made). I would like to automate it with EventGhost. I ordered 315mhz RF receiver/transmitter kit
similar to described here: http://www.buildcircuit.com/how-to-use- ... h-arduino/
and USB to RS232 TTL adapter for my PC, similar to this: http://www.ebay.com/itm/New-PL2303-USB- ... 1e6d4e0cd0

Both receiver and transmitter needs 4 lines, VCC, GND, DATA and Antenna. VCC, GND and Antenna are all easy to take care of. Do you think such a config is possible:
PC Serial USB RXD -> Receiver Data line
PC Serial USB TXD -> Transmitter Data line

And I get Serial data information in EventGhost? What I would like to is, triggering sensors (door, window, PIR etc) and generate events in EventGhost. Also triggering remote control buttons, recording events again, and later use these to disarm/arm the unit through EventGhost. I'm not interested in protocol, decoding etc, all I would like to do is record some kind of repeatable input (and I know these cheap systems repeat the same signal always) and repeat it through EventGhost Serial Port plugin.

do you think this is possible with only the hardware I mentioned? Would I need any middle man etc? Thanks a lot for any comments and thoughts in advance.
