Hello.
I have been looking in to controling some cheap remote RF Switches.. like http://www.clasohlson.no/Product/Product.aspx?id=155691616.
They use SC2262 on the transmitter and SC2272 on the recievers.  http://electronics-diy.com/pdf/SC2272_eng.pdf and http://www.sc-tech.cn/en/sc2262.pdf

I started by looking at the Library for "RF remote switches" Topic in the old forum http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1216065789. Its supports chips like the PT2262 witch sould be compatible with SC2262, so I thought that it would work for my switches as well. But it seems like its a NO GO.

Basicly what I am trying to do is using the Arduino as the transmitter without pulling wires, just sending the right code over the 433.92 mhz transmitter.

I stumbled across the Arduinoha http://code.google.com/p/arduinoha/, but I havent gotten mutch sense out of it. The problems with theese systems is that then have many names for the same type. They are mostly nobrand things.

My question is if anybody has any experience with any of this, that they could share? I will certainly share my findings here.

Hi there, how are you going with this?,

I am also looking to emulate the SC2262 encoder using the arduino. Jaycar in Australia (and a heap of other devices around the globe) also have this http://www.jaycar.com.au/productView.asp?ID=MS6140

I am happy to share my findings once I get up and running. May even do a shield for this.

I have just finished part of my project with help of this http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1216065789
you cant use it for chacon receivers and transmitters also.

It was a huge help without this topic I wouldn't get anywhere smiley-razz but now I can learn emitted codes from any remote
then send them from Arduino have a look at topic.

I'm also using Arduino to control all windows blinds of my house.

 I have thought about automating my window, so I would like to know which actuator you use to turn the window blinds?

I think I see a few "bugs" in that wiring...

Hi all,

I'm intending to do something similar. I've already got some old remote power switches that run at 433.92Mhz, but I'm not sure what transmitter to get for my Arduino - would this work? http://proto-pic.co.uk/products/RF-Link-Transmitter-%252d-434MHz.html

The details say 434Mhz - is this just "shorthand" for 433.92Mhz or have I totally missed the point?

Thanks.

finster: Not sure, I think it is a 433.92 (on the crystal on the picture is says 433), but im not sure. I have seen some that are marked 433 and 434.. and when I look at the Datasheet it turns out its 433.92 most of the time. Maby check out digikey.com

GSI2: Nice to see what you have done.. But whats that remote with the wires on the buttons? Are you pulling wires as well? What type of switches did you use? I haven't continued with this project, got sidetracked by openwrt. But now I would like to continue. Did you use the transmitter on the remote? Or did you use a separate transmitter? Did you "record" the signals from the remote on the arduino? If so, did you use a separate receiver, or the one on the devices?

In answer to my own question, I just bought one of these: http://www.quasaruk.co.uk/acatalog/AM_Transmitter_-_TX1.html and one of these: http://www.quasaruk.co.uk/acatalog/AM_Receiver_-_RX2.html off ebay. Even though it says 433MHz on the specs, they have stickers on them saying "A434" and more importantly I've got them receiving and transmitting to my 433.92Mhz remote power switches (with the excellent RemoteSwitchLibrary at the top of this thread: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1216065789).

Hope that helps somebody!

i have a same remote switch product (called "GA" like mentioned).
I've hook my arduino with TX433 transmitter (4 pin) and send any possibilities code for kaKuSwitch, actionSwitch, blokkerSwitch using RemoteSwitchLibrary from Randy Simons, with no one success result.

When i tried to soldering the button pad from the remote control, i got trouble finding the pinout for connecting to my photocoupler/relay because there's at least 3 pinout for each button, any idea?


Thanks in advance

I worked on a project like this. In the end I used the Arduino to emulate the SC2262 output (http://arduino.cc/forum/index.php?topic=60669.0). It works just fine, although things have moved on.  I'm back here though, as I want to port to a Netduino plus - and, as Netduino's don't support microsecond delays, I'll have to use an SC2262 instead (or a slaved arduino, or give up and make the refuelling monitor for my wife's wood-burning stove I promised her about a year ago).
