# v3.3.0 (Development release 3.3)
# The module is inspired by the FHEMduino project and modified in serval ways for processing the incomming messages
# see http://www.fhemwiki.de/wiki/SIGNALDuino
# It was modified also to provide support for raw message handling which can be send from the SIGNALduino
# The purpos is to use it as addition to the SIGNALduino which runs on an arduno nano or arduino uno.
# It routes Messages serval Modules which are already integrated in FHEM. But there are also modules which comes with it.

<h3>SIGNALduino</h3>

	<table>
	<tr><td>
	The SIGNALduino ia based on an idea from mdorenka published at <a
	href="http://forum.fhem.de/index.php/topic,17196.0.html">FHEM Forum</a>.

	With the opensource firmware (see this <a
	href="https://github.com/RFD-FHEM/SIGNALduino">link</a>) it is capable
	to receive and send different protocols over different medias. Currently are 433Mhz protocols implemented.
	<br><br>

	The following device support is currently available:
	<br><br>


	Wireless switches  <br>
	ITv1 & ITv3/Elro and other brands using pt2263 or arctech protocol--> uses IT.pm<br>

	<br><br>
	Temperatur / humidity senso
	<ul>
	<li>PEARL NC7159, LogiLink WS0002,GT-WT-02,AURIOL,TCM97001, TCM27 and many more -> 14_CUL_TCM97001 </li>
	<li>Oregon Scientific v2 and v3 Sensors  -> 41_OREGON.pm</li>
	<li>Temperatur / humidity sensors suppored -> 14_SD_WS07</li>
    <li>technoline WS 6750 and TX70DTH -> 14_SD_WS07</li>
    <li>Eurochon EAS 800z -> 14_SD_WS07</li>
    <li>CTW600, WH1080	-> 14_SD_WS09 </li>
    <li>Hama TS33C, Bresser Thermo/Hygro Sensor -> 14_Hideki</li>
    <li>FreeTec Aussenmodul NC-7344 -> 14_SD_WS07</li>
	</ul>
	<br><br>

	It is possible to attach more than one device in order to get better
	reception, fhem will filter out duplicate messages.<br><br>

	Note: this module require the Device::SerialPort or Win32::SerialPort
	module. It can currently only attatched via USB.

	<b>Define</b><br>
	<code>define &lt;name&gt; SIGNALduino &lt;device&gt; </code> <br>
	<br>
	USB-connected devices (SIGNALduino):<br>
	<ul><li>
		&lt;device&gt; specifies the serial port to communicate with the SIGNALduino.
		The name of the serial-device depends on your distribution, under
		linux the cdc_acm kernel module is responsible, and usually a
		/dev/ttyACM0 or /dev/ttyUSB0 device will be created. If your distribution does not have a
		cdc_acm module, you can force usbserial to handle the SIGNALduino by the
		following command:
		<ul>
		modprobe usbserial 
		vendor=0x03eb
		product=0x204b
		</ul>In this case the device is most probably
		/dev/ttyUSB0.<br><br>

		You can also specify a baudrate if the device name contains the @
		character, e.g.: /dev/ttyACM0@57600<br><br>This is also the default baudrate

		It is recommended to specify the device via a name which does not change:
		e.g. via by-id devicename: /dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0@57600

		If the baudrate is "directio" (e.g.: /dev/ttyACM0@directio), then the
		perl module Device::SerialPort is not needed, and fhem opens the device
		with simple file io. This might work if the operating system uses sane
		defaults for the serial parameters, e.g. some Linux distributions and
		OSX.  <br><br>
		</li>

	</ul>

	<li><a href="#do_not_notify">do_not_notify</a></li>
    <li><a href="#attrdummy">dummy</a></li>
    <li>debug<br>
    This will bring the module in a very verbose debug output. Usefull to find new signals and verify if the demodulation works correctly.
    </li>
    <li>flashCommand<br>
    	This is the command, that is executed to performa the firmware flash. Do not edit, if you don't know what you are doing.<br>
    	The default is: avrdude -p atmega328P -c arduino -P [PORT] -D -U flash:w:[HEXFILE] 2>[LOGFILE]<br>
		It contains some place-holders that automatically get filled with the according values:<br>
		<ul>
			<li>[PORT]<br>
			is the port the Signalduino is connectd to (e.g. /dev/ttyUSB0) and will be used from the defenition</li>
			<li>[HEXFILE]<br>
			is the .hex file that shall get flashed. There are three options (applied in this order):<br>
			- passed in set flash<br>
			- taken from the hexFile attribute<br>
			- the default value defined in the module<br>
			</li>
			<li>[LOGFILE]<br>
			The logfile that collects information about the flash process. It gets displayed in FHEM after finishing the flash process</li>
		</ul>
    
    </li>
    <li>hardware<br>
    When using the flash command, you should specify whar hardware you have connected to the usbport. Doing not, can cause failures of the device.
    </li>
    <li>minsecs<br>
    This is a very special attribute. It is provided to other modules. minsecs should act like a threshold. All logic must be done in the logical module. 
    If specified, then supported modules will discard new messages if minsecs isn't past.
    </li>
    <li>longids<br>
        Comma separated list of device-types for SIGNALduino that should be handled using long IDs. This additional ID allows it to differentiate some weather sensors, if they are sending on the same channel. Therfor a random generated id is added. If you choose to use longids, then you'll have to define a different device after battery change.<br>
		Default is to not to use long IDs for all devices.
      <br><br>
      Examples:<PRE>
# Do not use any long IDs for any devices:
attr sduino longids 0
# Use any long IDs for all devices (this is default):
attr sduino longids 1
# Use longids for BTHR918N devices.
# Will generate devices names like BTHR918N_f3.
attr sduino longids BTHR918N
</PRE></li>
<li>whitelistIDs<br>
This attribute allows it, to specify whichs protocos are considured from this module.
Protocols which are not considured, will not generate logmessages or events. They are then completly ignored. 
This makes it possible to lower ressource usage and give some better clearnes in the logs.
You can specify multiple whitelistIDs wih a colon : 0,3,7,12<br>
With a # at the beginnging whitelistIDs can be deactivated.
</li><br>
   <li>WS09_Model<br>
   WS09_WSModel:undef -> check all, WH1080 -> support WH1080/WS0101 , CTW600 -> support CTW600 
   </li>
   <li>WS09_CRCAUS<br>
   WS09_CRCAUS:0,1
   WS09_CRCAUS = 0 is default -> check CRC Calculation for WH1080
   </li><br>

		</li><br>
		<li>close<br>
		Closes the connection to the device.
		</li><br>
		<li>flash [hexFile]<br>
			The SIGNALduino needs the right firmware to be able to receive and deliver the sensor data to fhem. In addition to the way using the
			arduino IDE to flash the firmware into the SIGNALduino this provides a way to flash it directly from FHEM.

			There are some requirements:
			<ul>
				<li>avrdude must be installed on the host<br>
					On a Raspberry PI this can be done with: sudo apt-get install avrdude</li>
				<li>the hardware attribute must be set if using any other hardware as an Arduino nano<br>
					This attribute defines the command, that gets sent to avrdude to flash the uC.<br></li>
		     	<br>
	
			</ul>
		</li>
		<li>sendMsg<br>
		This command will create the needed instructions for sending raw data via the signalduino. Insteaf of specifying the signaldata by your own you specify 
		a protocol and the bits you want to send. The command will generate the needed command, that the signalduino will send this.
		<br><br>
		Please note, that this command will work only for MU or MS protocols. You can't transmit manchester data this way.
		<br><br>
		Input args are:
		<p>
		P<protocol id>#binarydata#R<num of repeats>#C<optional clock>   (#C is optional) 
		<br>Example: P0#0101#R3#C500
		<br>Will generate the raw send command for the message 0101 with protocol 0 and instruct the arduino to send this three times and the clock is 500.
		<br>SR;R=3;P0=500;P1=-9000;P2=-4000;P3=-2000;D=03020302;
		</p>
		
		</li><br>
		<li>enableMessagetype<br>
			Allows you to enable the message processing for 
			<ul>
				<li>messages with sync (syncedMS),</li>
				<li>messages without a sync pulse (unsyncedMU) </li>
				<li>manchester encoded messages (manchesterMC) </li>
			</ul>
			The new state will be saved into the eeprom of your arduino.
		</li><br>
		<li>disableMessagetype<br>
			Allows you to disable the message processing for 
			<ul>
				<li>messages with sync (syncedMS),</li>
				<li>messages without a sync pulse (unsyncedMU)</li> 
				<li>manchester encoded messages (manchesterMC) </li>
			</ul>
			The new state will be saved into the eeprom of your arduino.
		</li>
