<h3>TRX</h3>
<ul>
<table>
This module is for the <a href="http://www.rfxcom.com">RFXCOM</a> RFXtrx433 USB based 433 Mhz RF transmitters.
This USB based transmitter is able to receive and transmit many protocols like Oregon Scientific weather sensors, X10 security and lighting devices, ARC ((address code wheels) HomeEasy, KlikAanKlikUit, ByeByeStandBy, Intertechno, ELRO,
AB600, Duewi, DomiaLite, COCO) and others. <br>
Currently the following parser modules are implemented: <br>
<ul>
<li> 46_TRX_WEATHER.pm (see device <a href="#TRX">TRX</a>): Process messages Oregon Scientific weather sensors.
See <a href="http://www.rfxcom.com/oregon.htm">http://www.rfxcom.com/oregon.htm</a> for a list of
Oregon Scientific weather sensors that could be received by the RFXtrx433 tranmitter.
Until now the following Oregon Scientific weather sensors have been tested successfully: BTHR918, BTHR918N, PCR800, RGR918, THGR228N, THGR810, THR128, THWR288A, WTGR800, WGR918. It will also work with many other Oregon sensors supported by RFXtrx433. Please give feedback if you use other sensors.<br>
</li>
<li> 46_TRX_SECURITY.pm (see device <a href="#TRX_SECURITY">TRX_SECURITY</a>): Receive X10, KD101 and Visonic security sensors.</li>
<li> 46_TRX_LIGHT.pm (see device <a href="#RFXX10REC">RFXX10REC</a>): Process X10, ARC, ELRO AB400D, Waveman, Chacon EMW200, IMPULS, RisingSun, Philips SBC, AC, HomeEasy EU and ANSLUT lighting devices (switches and remote control). ARC is a protocol used by devices from HomeEasy, KlikAanKlikUit, ByeByeStandBy, Intertechno, ELRO, AB600, Duewi, DomiaLite and COCO with address code wheels. AC is the protocol used by different brands with units having a learning mode button:
KlikAanKlikUit, NEXA, CHACON, HomeEasy UK.</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.
<br><br>
<a name="TRXdefine"></a>
<b>Define</b>
<ul>
<code>define &lt;name&gt; TRX &lt;device&gt; [noinit] </code><br>
</ul>
<br>
USB-connected:<br><ul>
&lt;device&gt; specifies the USB port to communicate with the RFXtrx433 receiver.
Normally on Linux the device will be named /dev/ttyUSBx, where x is a number.
For example /dev/ttyUSB0. Please note that RFXtrx433 normally operates at 38400 baud. You may specify the baudrate used after the @ char.<br>
<br>
Example: <br>
<code>define RFXTRXUSB TRX /dev/ttyUSB0@38400</code>
<br>
</ul>
<br>
Network-connected devices:
<br><ul>
&lt;device&gt; specifies the host:port of the device. E.g.
192.168.1.5:10001
</ul>
<ul>
noninit is optional and issues that the RFXtrx433 device should not be
initialized. This is useful if you share a RFXtrx433 device via LAN. It is
also useful for testing to simulate a RFXtrx433 receiver via netcat or via
FHEM2FHEM.
<br>
<br>
Example: <br>
<code>define RFXTRXTCP TRX 192.168.1.5:10001</code>
<br>
<code>define RFXTRXTCP2 TRX 192.168.1.121:10001 noinit</code>
<br>
</ul>

<b>Attributes</b>
<ul>
<li><a href="#attrdummy">dummy</a></li><br>
<li>longids<br>
Comma separated list of device-types for TRX_WEATHER 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 no long IDs.
<br><br>
Examples:<PRE>
# Do not use any long IDs for any devices (this is default):
attr RFXCOMUSB longids 0
# Use long IDs for all devices:
attr RFXCOMUSB longids 1
# Use longids for BTHR918N devices.
# Will generate devices names like BTHR918N_f3.
attr RFXTRXUSB 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 RFXTRXUSB longids TX3_T,TX3_H</PRE>
</li><br>
<li>rssi<br>
1: enable RSSI logging, 0: disable RSSI logging<br>
Default is no RSSI logging.
<br><br>
Examples:<PRE>
# Do log rssi values (this is default):
attr RFXCOMUSB rssi 0
# Enable rssi logging for devices:
attr RFXCOMUSB rssi 1
</li><br>
</ul>
