I've tried this one: http://www.smarthousestore.co.uk/wd18-w ... ector.html
It looks rather strange but it works just fine with RFXCOM. It sends X10 security on 433MHz
It's quite loud but with care you can disconnect the alarm.

Re: RFXtrx433 communicating within linux
1. You might want to add a raw into your stty or see if php has any access to termios 2. Once you have read the number of bytes you expect, what happens if you try to read them all in one call to fread? 3. Does the RFXtrx433 have any equivalent of 32-bit or variable-length mode? Have you got the bau...

Multi-channel gas sensor
sniffer.jpg Here is an experimental sniffing device before I put the lid on. There are seven sensors on the board with room for one more. The PIC does the A to D and sends the results down USB to the host where they are turned into a vector, each element proportional to the log of the concentration...

Re: RFXtrx433 communicating within linux
Can you post the code that you are using to read from the RFXtrx433?
I have an RFXCOM receiver and I write in C but I might be able to see if there's anything wrong.
Cheers, Steve

Re: CO2 sensors
I'm using a Hanwei MG-811 for sensing CO2. It needs 6V at around 200mA (for the heater) and a very high impedance buffer and then it will give you an output of roughly 500-300mV for CO2 concentration of 350-10000ppm
You could feed that output after you've buffered it to an RFXsensor.

Re: Creating a 1-wire bus
http://www.1wire.org/media/A_Guide_to_the_1WRJ45_Standard_Draft.zip This is not an official standard by Dallas or Maxim, it's a proposed one and it works perfectly for me. I use the 6-pin RJ-12 connections and colours so I don't get it confused with Ethernet :) but otherwise RJ-45 might well be bett...

Re: How easy is it to control RFXCOM products from linux?
It's very easy. I've been using a USB RFXCOM receiver for years now with no problems at all. I use it for all my RF. You talk to the USB version through the Linux USB <-> serial driver (ftdi_sio.ko) RFXCOM supply all the documentation you need and the technical support is of course excellent! There'...

SMJ PT2262 remote sockets
Hi there, RFXCOM http://www.rfxcom.com/ make a USB transmitter which can send many different RF protocols. I don't know if it can accept a raw binary on off sequence but it might be worth checking first. Meanwhile... Hardware: A FTDI http://www.ftdichip.com/ UM245R USB->parallel FIFO (perhaps from F...

Yes, that will be fine. Give me a couple of days and I'll see what I've got here.

Yes they could, but that might be a little bit untidy. I can do a wiring diagram for you with some C code.
One issue though - are you using Windows? My stuff works for Linux, not Windows.

SMJ PT2262 remote sockets
The PT2262 modulates the RF into a serial code indicating which button you pressed on the transmitter and whether you want it on or off. Inside the SMJ plugs, there's a PT2272 which decodes the RF. If the decoded pattern matches the setting on the plug then the device is turned on or off. So all we ...

SMJ PT2262 remote sockets
X10 is probably the cheapest to start with, but sometimes it's not very reliable. Here's a good UK supplier: http://www.simplyautomate.co.uk/ You could get a CM12 module (which comes with basic software for Windows) and a light or appliance module then experiment. I'm sure other people will have oth...

How do you trigger your light?
Sunrise/sunset times don't work - there might be heavy cloud or a solar eclipse (8-) But my MS13 too sees the outside lights as daylight; there's nowhere else I can position it. So... if it's dark AND there's motion, it turns the light on for 50 seconds then it turns it off again. That seems to work...
