<h3>USBWX</h3>
|
|
<ul>
|
|
The USBWX module interprets the messages received by the ELV <a
|
|
href="http://www.elv.de/output/controller.aspx?cid=74&detail=10&detail2=29870">USB-WDE1</a>
|
|
weather receiver. This receiver is compaptible with the following ELV sensors:
|
|
KS200/KS300, S300IA, S300TH, ASH2200, PS50. It also known to work with Conrad
|
|
weather sensors KS555, S555TH and ASH555.<br> This module was tested with ELV
|
|
S300TH, ELV ASH2200, ELV KS300, Conrad S555TH and Conrad KS555. <br> Readings
|
|
and STATE of temperature/humidity sensors are compatible with the CUL_WS
|
|
module. For KS300/KS555 sensors STATE is compatible with the KS300 module. The
|
|
module is integrated into autocreate to generate the appropriate filelogs and
|
|
weblinks automatically.
|
|
<br><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> USBWX <serial device></code>
|
|
<br>
|
|
<br>Defines USB-WDE1 attached via usb.<br>
|
|
<br>
|
|
<code>define <name> USBWX <code> [corr1...corr4]</code> <br>
|
|
<br>
|
|
<code> is the code which must be set on the sensor. Valid values
|
|
are 1 through 8. <br> 9 is used as the sensor id of the ks300 sensor.<br>
|
|
corr1..corr4 are up to 4 numerical correction factors, which will be added
|
|
to the respective value to calibrate the device. Note: rain-values will be
|
|
multiplied and not added to the correction factor.
