View Full Version : Usb X10 Receiver - Generic X10 Plugin - no device code

April 24th, 2005, 10:59 AM
I would like to use a usb-rf receiver (cm21a) with girder. The problem is that
girder only shows the command code (on,off) but no house and device code.
I installed a usb sniffer programm, and this shows 5 bytes for each command -
including house and device code. Is there a generic usb plugin to use this byte
sequence as command or
is there a work around or any possibility to get it working?

Isn't there an x10 activex object to use with this device. Would work with luacom...

thanks for the hint Mike,
i tried to use the activex object in vb to test it. I managed to receive the commands but - surprise - also without house and device code.
Is this a problem of the x10 driver?
Is that also the reason why Ron's plugin doesnt has the house and device code?

You should get a house and device code before the on/off code. I wouldn't expect it as part of the on/off code.

rah99, why do you think that the house and device code comes before the command code? As far is i know and experienced the remote transmits only if you press a command key, not when you select the device or housecode.
In the activex object, there is only one event, which will be fired when a command is received. There are variables for house and device code and some more, but they are all empty, except of the command code.

It depends on how the ActiveX works I suppose (I haven't used it), I was basing my comment on the way that the X10 powerline protocol works. ie you'll get the house and device code(s) transmitted first, then the on/off/dim commands. This may all occur in one batch when the on/off button is pressed.

It's possible that the RF protocol is different.
