# 40_RFXCOM.pm
|
|
# Modul for FHEM
|
|
#
|
|
# Tested with USB-RFXCOM-Receiver (433.92MHz, USB, order code 80002)
|
|
# (see http://www.rfxcom.com/).
|
|
# To use this module, you need to define an RFXCOM receiver:
|
|
# define RFXCOM RFXCOM /dev/ttyUSB0
|
|
#
|
|
# The module also has code to access LAN based RFXCOM receivers like 81003 and 83003.
|
|
#
|
|
# To use it define the IP-Adresss and the Port:
|
|
# define RFXCOM RFXCOM 192.168.169.111:10001
|
|
# optionally you may issue not to initialize the device (useful for FHEM2FHEM raw
|
|
# and if you share an RFXCOM device with other programs)
|
|
# define RFXCOM RFXCOM 192.168.169.111:10001 noinit
|
|
#
|
|
# The RFXCOM receivers supports lots of protocols that may be implemented for FHEM
|
|
# writing the appropriate FHEM modules.
|
|
# Special thanks to RFXCOM, http://www.rfxcom.com/, for their help.
|
|
# I own an USB-RFXCOM-Receiver (433.92MHz, USB, order code 80002) and highly recommend it.
|
|
#
|
|
# The module 41_OREGON.pm implements the decoding of the Oregon Scientific weather sensors.
|
|
# It is derived from xPL Perl (http://www.xpl-perl.org.uk/). I suggest to look there
|
|
# if you want to implement other protocols.

<h3>RFXCOM</h3>
|
|
<ul>
|
|
This module is for the old <a href="http://www.rfxcom.com">RFXCOM</a> USB or LAN based 433 Mhz RF receivers and transmitters (order order code 80002 and others). It does not support the new RFXtrx433 transmitter because it uses a different protocol. See <a href="#RFXTRX">RFXTRX</a> for support of the RFXtrx433 transmitter.<br>
|
|
These receivers supports many protocols like Oregon Scientific weather sensors, RFXMeter devices, X10 security and lighting devices and others. <br>
|
|
Currently the following parser modules are implemented: <br>
|
|
<ul>
|
|
<li> 41_OREGON.pm (see device <a href="#OREGON">OREGON</a>): Process messages Oregon Scientific weather sensors.
|
|
See <a href="http://www.rfxcom.com/oregon.htm">http://www.rfxcom.com/oregon.htm</a> of
|
|
Oregon Scientific weather sensors that could be received by the RFXCOM receivers.
|
|
Until now the following Oregon Scientific weather sensors have been tested successfully: BTHR918, BTHR918N, PCR800, RGR918, THGR228N, THGR810, THR128, THWR288A, WTGR800, WGR918. It will probably work with many other Oregon sensors supported by RFXCOM receivers. Please give feedback if you use other sensors.<br>
|
|
</li>
|
|
<li> 42_RFXMETER.pm (see device <a href="#RFXMETER">RFXMETER</a>): Process RFXCOM RFXMeter devices. See <a href="http://www.rfxcom.com/sensors.htm">http://www.rfxcom.com/sensors.htm</a>.</li>
|
|
<li> 43_RFXX10REC.pm (see device <a href="#RFXX10REC">RFXX10REC</a>): Process X10 security and X10 lighting devices. </li>
|
|
</ul>
|
|
<br>
|
|
Note: this module requires the Device::SerialPort or Win32::SerialPort module
|
|
if the devices is connected via USB or a serial port.

<b>Define</b>
|
|
<ul>
|
|
<code>define <name> RFXCOM <device> [noinit] </code><br>
|
|
</ul>
|
|
<br>
|
|
USB-connected (80002):<br><ul>
|
|
<device> specifies the USB port to communicate with the RFXCOM receiver.
|
|
Normally on Linux the device will be named /dev/ttyUSBx, where x is a number.
|
|
For example /dev/ttyUSB0.<br>
|
|
<br>
|
|
Example: <br>
|
|
<code>define RFXCOMUSB RFXCOM /dev/ttyUSB0</code>
|
|
<br>
|
|
</ul>
|
|
<br>
|
|
Network-connected devices:
|
|
<br><ul>
|
|
<device> specifies the host:port of the device. E.g.
|
|
192.168.1.5:10001
|
|
</ul>
|
|
<ul>
|
|
noninit is optional and issues that the RFXCOM device should not be
|
|
initialized. This is useful if you share a RFXCOM device. It is also useful
|
|
for testing to simulate a RFXCOM receiver via netcat or via FHEM2FHEM.
|
|
<br>
|
|
<br>
|
|
Example: <br>
|
|
<code>define RFXCOMTCP RFXCOM 192.168.1.5:10001</code>
|
|
<br>
|
|
<code>define RFXCOMTCP2 RFXCOM 192.168.1.121:10001 noinit</code>
|
|
<br>
|
|
</ul>
|
|
<br>
|
|
<ul>
|
|
<li><a href="#attrdummy">dummy</a></li><br>
|
|
<li>longids<br>
|
|
Comma separated list of device-types for RFXCOM that should be handled using long IDs. This additional ID is a one byte hex string and is generated by the Oregon sensor when is it powered on. The value seems to be randomly generated. This has the advantage that you may use more than one Oregon sensor of the same type even if it has no switch to set a sensor id. For example the author uses two BTHR918N sensors at the same time. All have different deviceids. The drawback is that the deviceid changes after changing batteries. All devices listed as longids will get an additional one byte hex string appended to the device name.<br>
|
|
Default is to use long IDs for all devices.
|
|
<br><br>
|
|
Examples:<PRE>
|
|
# Do not use any long IDs for any devices:
|
|
attr RFXCOMUSB longids 0
|
|
# Use any long IDs for all devices (this is default):
|
|
attr RFXCOMUSB longids 1
|
|
# Use longids for BTHR918N devices.
|
|
# Will generate devices names like BTHR918N_f3.
|
|
attr RFXCOMUSB longids BTHR918N
|
|
# Use longids for TX3_T and TX3_H devices.
|
|
# Will generate devices names like TX3_T_07, TX3_T_01 ,TX3_H_07.
|
|
attr RFXCOMUSB longids TX3_T,TX3_H</PRE>
