# Needs SIGNALduino.
# Published under GNU GPL License, v2
# History:
# 0.10	2016-02-16	Jarnsen		initial template
# 0.20	2016-03-06	darkmission	first functions, renamed from 10_ to 99_
# 0.21	2016-03-06	darkmission	Bug default channel corrected, changed attribute repetition to SignalRepeats
# 0.22  2016-03-10	darkmission	code cleaned, renamed from 99_ to 98_
# 0.23  2016-03-11	Jarnsen		AttrList cleaned and change priority
# 1.00	2016-03-12	darkmission	autocreate, parse communication from SIGNALduino for correct position when using remote from doooya 
# 1.10  2016-03-13	Ralf9		changed SendCommand with sendMsg
# 1.11  2016-03-17	Ralf9   	ID + Channel = DeviceCode
# 1.12  2016-04-26      Jarnsen     im Dooya parse cmd geändert
# 1.13	2017-08-26	darkmission	Update state when called by remote, little code cleaning (setlist and go-my deleted), some more debug messages

#TODOS:
# - Groups, diff by channels

### New set (state) method (using internalset)
###
### Reimplemented calculations for position readings and state
### Allowed sets to be done without sending actually commands to the blinds
### 	syntax set <name> [ <virtual|send> ] <normal set parameter>
### position and state are also updated on stop or other commands based on remaining time
### position is handled between 0 and 100 blinds down but not completely closed and 200 completely closed
### 	if timings for 100 and close are equal no position above 100 is used (then 100 == closed)
### position is rounded to a value of 5 and state is rounded to a value of 10
#
### General assumption times are rather on the upper limit to reach desired state


# Readings
## state contains rounded (to 10) position and/or textField
## position contains rounded position (limited detail)

# STATE
## might contain position or textual form of the state (same as STATE reading)

<h3>Dooya protocol</h3>
<ul>
  The Dooya protocol is used by a wide range of devices,
  which are either senders or receivers/actuators.
  The RECIVING and SENDING of Dooya commands is implemented in the SIGNALduino, so this module currently supports 
  devices like blinds and shutters. The Dooya protocol is used from a lot of different shutter companies in Germanyr. Examples are Rohrmotor24 or Nobily.
  <br><br>

  <code>4: SIGNALduino_unknown found shutter from Dooya. id=3606104, remotetype=14,  channel=1, direction=down, all_shutters=false</code>  
  </pre>

  
   <br> a <a href="#SIGNALduino">SIGNALduino</a> device (must be defined first)  <br>
 <br>
 <br>

   
  <a name="Dooyadefine"></a>
   <br>
  <b>Define</b>
   <br>
  <ul>
    <code>define &lt;name&gt; Dooya &lt;id&gt;_&lt;channel&gt; </code>
  <br>
 <br>
   The id is a 28-digit binar code, that uniquely identifies a single remote control.
   <br>
   Pairing is done by setting the shutter in programming mode, either by disconnecting/reconnecting the power,
   and by pressing the program button on an already associated remote.
   <br>
   Once the shutter is in programming mode, send the "prog" command from within FHEM to complete the pairing.
   The shutter will peep shortly to indicate completion.
   <br>
   You are now able to control this blind from FHEM, the receiver thinks it is just another remote control or the real exist remote. 
   For the shutter it´s the same.

   <ul>
   <li><code>&lt;id&gt;</code> is a 28 digit binar number that uniquely identifies FHEM as a new remote control.
   <br>You can use a different one for each device definition, and group them using a structure. You can use the same ID for a couple of shutters
   and you can give every one an other channel. (0 to 15, 0 ist the MASTER and conrols all other channels.)
   If you set one of them, you need to pick the same address as an existing remote. You can create the Device with autocreate with a real remote or manuel without remote control.</li>
   </ul>
   <br>

    Examples:
    <ul>
	  <code>define Rollo_Master Dooya 0011011100000110010110001110_0</code><br> Rollo_Master channel 0 controls all shutters (channel 1 - 15) with the same ID, in this case Rollo_1 and Rollo_2 <br>
	  <br>
      <code>define Rollo_1 Dooya 0011011100000110010110001110_1</code><br> Rollo_1 channel 1<br>
      <code>define Rollo_2 Dooya 0011011100000110010110101110_2</code><br> Rollo_2 channel 2<br>
    </ul>
  </ul>
  <br>

  <a name="Dooyaset"></a>
  <b>Set </b>
  <ul>
    <code>set &lt;name&gt; &lt;value&gt; [&lt;time&gt]</code>
    <br><br>
    where <code>value</code> is one of:<br>
    <pre>
    on
    off
    stop
    pos value (0..100) # see note
    prog  # Special, see note
    </pre>
    Examples:
    <ul>
      <code>set rollo_1 on</code><br>
      <code>set rollo_1 on,sleep 1,rollo_2 on,sleep 1,rollo_3 on</code><br>
      <code>set rollo_1 off</code><br>
      <code>set rollo_1 pos 50</code><br>
    </ul>
    <br>
    Notes:
    <ul>
      <li>prog is a special command used to pair the receiver to FHEM:
      Set the receiver in programming mode and send the "prog" command from FHEM to finish pairing.<br>
      The shutter will peep shortly to indicate success.
      </li>
      <li>pos value<br>
		
			The position is variying between 0 completely open and 100 for covering the full window.
			The position must be between 0 and 100 and the appropriate
			attributes drive-down-time-to-100, drive-down-time-to-close,
			drive-up-time-to-100 and drive-up-time-to-open must be set.<br>
	  </li>
	</ul>

		The position reading distinuishes between multiple cases
    <ul>
      <li>Without timing values set only generic values are used for status and position: <pre>open, closed, moving</pre> are used
      </li>
	  <li>With timing values set but drive-down-time-to-close equal to drive-down-time-to-100 and drive-up-time-to-100 equal 0 
			the device is considered to only vary between 0 and 100 (100 being completely closed)
      </li>
	  <li>With full timing values set the device is considerd a window shutter (Rolladen) with a difference between 
			covering the full window (position 100) and being completely closed (position 200)
      </li>
	</ul>

  </ul>
  <br>

  <b>Get</b> 
  <ul>N/A</ul><br>

  <a name="Dooyaattr"></a>
  <b>Attributes</b>
  <ul>
    <a name="IODev"></a>
    <li>IODev<br>
        Set the IO or physical device which should be used for sending signals
        for this "logical" device. It must be the SIGNALduino.<br>
        Note: The IODev has to be set, otherwise no commands will be sent!<br>
    </li><br>

  <a name="channel"></a>
    <li>channel<br>
        Set the channel of the remote. You can use 0 (MASTER) to 15.<br>
        Note: The MASTER conrols all remotes with the same ID!!!<br>
    </li><br>
        
          <a name="SignalRepeats"></a>
    <li>SignalRepeats<br>
        Set the repeats for sending signal. You can use 5, 10, 15 and 20.
    </li><br>
        
    <a name="additionalPosReading"></a>
    <li>additionalPosReading<br>
        Position of the shutter will be stored in the reading <code>pos</code> as numeric value. 
        Additionally this attribute might specify a name for an additional reading to be updated with the same value than the pos.
	</li><br>




    <a name="eventMap"></a>
    <li>eventMap<br>
        Replace event names and set arguments. The value of this attribute
        consists of a list of space separated values, each value is a colon
        separated pair. The first part specifies the "old" value, the second
        the new/desired value. If the first character is slash(/) or comma(,)
        then split not by space but by this character, enabling to embed spaces.
        Examples:
        <ul><code>
        attr store eventMap on:open off:closed<br>
        attr store eventMap /on-for-timer 10:open/off:closed/<br>
        set store open
        </code>
        </ul>
    </li>
    <br>

    <li><a href="#do_not_notify">do_not_notify</a></li><br>
    <a name="attrdummy"></a>
    <li>dummy<br>
    Set the device attribute dummy to define devices which should not
    output any radio signals. Associated notifys will be executed if
    the signal is received. Used e.g. to react to a code from a sender, but
    it will not emit radio signal if triggered in the web frontend.
    </li><br>

    <li><a href="#loglevel">loglevel</a></li><br>

    <li><a href="#showtime">showtime</a></li><br>

    <a name="model"></a>
    
    <a name="ignore"></a>
    <li>ignore<br>
        Ignore this device, e.g. if it belongs to your neighbour. The device
        won't trigger any FileLogs/notifys, issued commands will silently
        ignored (no RF signal will be sent out, just like for the <a
        href="#attrdummy">dummy</a> attribute). The device won't appear in the
        list command (only if it is explicitely asked for it), nor will it
        appear in commands which use some wildcard/attribute as name specifiers
        (see <a href="#devspec">devspec</a>). You still get them with the
        "ignored=1" special devspec.
    </li><br>

    <a name="drive-down-time-to-100"></a>
    <li>drive-down-time-to-100<br>
        The time the blind needs to drive down from "open" (pos 0) to pos 100.<br>
		In this position, the lower edge touches the window frame, but it is not completely shut.<br>
