Controling remote power switches with RFM12Pi

Hi,

I have some questions considering RFM12Pi 433 Mhz version.

As I understood you have to flash the Full firmware to the RFM12Pi to have support for KAKU and FS20 protocols. This is written down in OpenEnergyMonitor wiki - thanks for that.

Is it possible to send FS20 command with 433 Mhz version of RFM12Pi as FS20 uses 868Mhz?

What is KAKU exactly? Is it a protocol? Where can I get switches using this protocol in Germany? Is there a list of devices using KAKU?

I also read in a forum that it is possible to control Elron power switches with RFM12Pi. Which is the command I have to use in minicom for that?

I Hope anyone can help me!

Best regards,

Christian

KAKA is an abbreviation of the Dutch Klik Aan Klik Uit. Literally click on, click off.

You can find more info at - http://jeelabs.org/?s=KAKU.

Asimple search on KAKU protocol with that well know search engine turned this up.

Hi Simon,

thank you for your help.

So KAKU is not a protocol but a brand / company selling remote power switches etc.

I found out, that there is a German brand called COCO and the website looks similar:

Durch: http://www.klikaanklikuit.nl/shop/nl/apa3-1500r/
German: http://www.coco-technology.com/shop/de/produkte/sets/apa3-1500r-1/#tabs

I wonder a little bit why the RFM12Pi developers implemented this remote switch type and not a more common one e.g. Home Easy for example!?

Or is there support for other switches / brands as well?

Best regards,

Christian

Christian,

There's all sorts of samples of code on the wiki.

I'm guessing that the ones you refer to were taken from the jeelib site. You'll see if you follow the link that there are many other examples there.

​The fact that they are on the wiki doesn't mean there won't be something around for home easy, it's probably that at the time of writing the wiki there were some sample code around for KAKU.

I suggest you start using that famous search engine if you need sample code for other protocols.

Hi Simon,

so you mean I can flash code on RFM12Pi Atmega chip to get RFM12Pi to work with nearly every remote switch working on 433Mhz?

Can you send me an example link? What exactly should I search for?

Best regards,
Christian

I would think so Christian, although of course you'll need the code for the pi as well.

A good place to start would be OpenHAB. Try asking your questions there.
