I am a noob in Home Automation, but eager to get my home smart. I just received my cheap 433Mhz Superheterodyne RF receiver and transmitter (from Aokin DiyMaker Store) which i connected to my Raspberry PI3.
There are many ways you can interact with 433MHz stuff. The method that I found working for my needs, at least for receiving (I have no need to transmit) is using RFLink. It needs to be installed on an Arduino Mega connected to your transmitter and superheterodyne receiver. It suit me well because I happen to have an old Arduino Mega sitting around unused. RFLink (on the Arduino) connects to the computer that runs OpenHAB (in your case, your Raspberry Pi?) via USB and it is seen as a serial link. I then use a Serial binding to read the data from RFLink. It’s a simple plain text data that I parsed using basic string parsing (splitting the delimiters). You would need to figure out how to flash the RFLink to Arduino, if you haven’t done that, it could be a challenge. You can find more info on rflink’s website about it. This place is more about how to connect that with openhab once you have a functioning device.
PS there seems to be a mention about “Kaku” on rflink’s site. Not sure if that’s the same device you have.
There are other, probably better/easier ways for sure, e.g. using Sonoff RF bridge, etc. I haven’t tried those so I can’t explain further.
I changed the title. Because RFX-com is a complete hardware product which contains, besides the 433 Mhz receivers and transmitters, hardware to connect that hardware via usb to a computer and software to convert the raw rf signals to readable signals.
What you now have is only some small part of the puzzle.The hardware can only send and receive signals and doesn’t know anything about protocols. So if you would want to make this work the way your approached this you need to decode the kaku protocol and then convert those signals into bits and bytes and then get that data into openHAB. For the latter you would probably need to write a binding, or write some python from the script you mentioned, because you need convert those signals to openHAB readable data.
If you like DIY this can be a feasible approach, but you would need to understand what you’re doing and not have to rely on asking basic questions, because it will simple be to hard to do.
If you just want to automate your house you can go either with the RFLink software mentioned by JimT. This needs some extra work and you need to know how to program an arduino among other things. Or invest in a RFX-com that works out-of-the box with openHAB.
I´m not experienced in this, (yet). I got myself a rtl-sdr dongle (DVB-T receiver) which I will be using when I get there. I just havn´t had time to look more into it, (because the dongle I bought has a too big cabin, so it can no go directly into a Rpi ).
