View Full Version : RFXCOM or W800RF32A

March 16th, 2009, 11:36 PM
question you all I am trying to decide on a RFXCOM or W800RF32A now i know there are a few things the rfxcom can receive that the W800RF32A can't, however my main question is this if getting the rfxcom should i get the receiver/transmitter or just the receiver? What devices actually will use the transmitter?

The 310MHz US version of the RFXCOM X10 receiver and the 310MHz W800RF32A have the same receiving capabilities.

The 433.92MHz W800RF32 can only receive X10 32 bits. The RFXCOM 433.92MHz can receive a long list of different device types. See for the full list: http://www.rfxcom.com/descr_433_X10_Oregon.htm

An RFXCOM USB or Ethernet interface can have the 2 receivers installed so that for example US 310MHz X10 and 433.92MHz Oregon Scientific sensors can be received the same time using one interface.

The 433.92MHz transmitter is for use outside the US and used to control HomeEasy, ByeByeStandBy, DomiaLite, KlikAanKlikUit, Nexa, Proove, Intertech, X10, Harrison electrical curtains ....

so basicly if i want to beable to run any of the Oregon Sensors i need the 433.92mhz version however for us x10 i would need the 310mhz version or the dual version am i getting this correct?

The 80003 USB 433.92MHz + 310MHz receivers will do all.

You can also select the 81004, 83004, 82004 or 85004 Ethernet versions. There is also a virtual COM port driver available for these Ethernet interfaces that runs on Windows (except on Vista 64).
The Ethernet interface can also be connected to the Internet and enables you to receive data from remote locations.

Select a 2 port version if you also want to control devices in the remote location:
- If X10 devices are to be controlled:
Add the 77000 RS232 Serial Interface module. http://www.rfxcom.com/transmitters.htm#77000 This allows you to connect an RS232 device for example a CM11.

- If European RF devices (HomeEasy, DomiaLite etc) are to be controlled:
Add the 70031 433.92MHz RF transmitter module. http://www.rfxcom.com/transmitters.htm#70031

So what is the cheapest way (device) to add USB RFXCOM to get Oregon Scientific sensors into Girder 5? I don't need X10 as I have a W800 and don't need to transmit either.

You can select the 80002 USB 433.92MHz receiver

I am now trying to switch all of my Oregon Sensors, etc. over to Girder. How do I get access to the temp/ etc sensors in girder.

I have the RFXCOM stating the status as 'Ok - Connected' in the Girder Component.

This is a question for Girder support.

You can test the Oregon receiving using the RFreceiver program http://www.rfxcom.com/documents/RFreceiver.zip
Use always Variable length Mode and Oregon receiving enabled.

I don't think we had any code to read the Oregon temp sensors - but it's been a very long time since I looked at the RFXCOM code.

I can't seem to find any code for this. Do you know if these can be supported?

I use these in all of my rooms to support zoned hvac with Homeseer. BTW, I am trying to eliminate Homeseer, as I am not very happy with its capabilities.

I'm sure they can be supported, there should be some documentation of the protocol on the RFXCOM website. Not sure I'll have any time to do this myself though, and without the hardware it's very difficult to test it.
