# 2015-08-16 V 0200 communication to server changes from xml to json
# 2015-08-16 V 0201 some standard requests after login which are not neccessary disabled (so the actual requests are not equal to flow of iphone app)
# 2016-02-14 V 0202 bugs forcing some startup warning messages fixed
# 2016-02-20 V 0203 perl exception while parsing json string captured
# 2016-02-24 V 0204 commands open,close,my,stop and setClosure added
# 2016-04-24 V 0205 commands taken from setup
# 2016-06-16 V 0206 updateDevices called for devices created before setup has been read
# 2016-11-15 V 0207 BLOCKING=0 can be used, all calls asynchron, attribut levelInvert inverts RollerShutter position
# 2016-11-29 V 0208 HttpUtils used instead of LWP::UserAgent, BLOCKING=0 set as default, umlaut can be used in Tahoma names
# 2016-12-15 V 0209 perl warnings during startup and login eliminated
# 2017-01-08 V 0210 tahoma_cancelExecutions: cancel command added
# 2017-01-10 V 0211 tahoma_getStates: read all states based on table {setup}{devices}[n]{definition}{states}
# 2017-01-24 V 0212 tahoma_getStates: read all states recovered
# 2017-01-24 V 0212 start scene with launchActionGroup so cancel is working on scenes now

=begin html

<a name="tahoma"></a>
<h3>tahoma</h3>
<ul>
  The module realizes the communication with io-homecontrol&reg; Devices e.g. from Somfy&reg; or Velux&reg;<br>
  A registered TaHoma&reg; Connect gateway from Overkiz&reg; sold by Somfy&reg; which is continously connected to the internet is necessary for the module.<br>
  <br><br>

  Notes:
  <ul>
    <li>JSON has to be installed on the FHEM host.</li>
    <li>on problems refer also the fhem forum <a href="https://forum.fhem.de/index.php/topic,28045.0.html">IO-Homecontrol Devices &uuml;ber Tahoma Box einbinden</a></li>
  </ul><br>

  <a name="tahoma_Define"></a>
  <b>Define</b>
  <ul>
    <code>define &lt;name&gt; tahoma ACCOUNT &lt;username&gt; &lt;password&gt;</code><br>
    <code>define &lt;name&gt; tahoma DEVICE &lt;DeviceURL&gt;</code><br>
    <code>define &lt;name&gt; tahoma PLACE &lt;oid&gt;</code><br>
    <code>define &lt;name&gt; tahoma SCENE &lt;oid&gt;</code><br>
    <br>
    <br>
    A definition is only necessary for a tahoma device:<br>
    <code>define &lt;name&gt; tahoma ACCOUNT &lt;username&gt; &lt;password&gt;</code><br>
    <b>If a tahoma device of the type ACCOUNT is created, all other devices acessable by the tahoma gateway are automaticaly created!</b><br>
    If the account is valid, the setup will be read from the server.<br>
    All registrated devices are automatically created with name tahoma_12345 (device number 12345 is used from setup)<br>
    All defined rooms will be are automatically created.<br>
    Also all defined scenes will be automatically created.<br>
    <br>
    <br>
    <b>global Attributes for ACCOUNT:</b>
    <ul>
      If autocreate is disabled, no devices, places and scenes will be created automatically:<br>
      <code>attr autocreate disable</code><br>
    </ul>
    <br>
    <b>local Attributes for ACCOUNT:</b>
    <ul>
      Normally, the web commands will be send asynchron, and this can be forced to wait of the result by blocking=1<br>
      <code>attr tahoma1 blocking 1</code><br>
    </ul>
    <br>
    <b>local Attributes for DEVICE:</b>
    <ul>
      If the closure value 0..100 should be 100..0, the level can be inverted:<br>
      <code>attr tahoma_23234545 levelInvert 1</code><br>
    </ul>
    <br>
    <b>local Attributes for PLACE:</b>
    <ul>
      The commands in a room will only affect the devices in the room with inClass=RollerShutter.<br>
      This can be extend or changed by setting the placeClasses attribut:<br>
      <code>attr tahoma_abc12345 placeClasses RollerShutter ExteriorScreen Window</code><br>
    </ul>
    <br>
    <b>Examples:</b>
    <ul>
      <code>define tahoma1 tahoma ACCOUNT abc@test.com myPassword</code><br>
      <code>attr tahoma1 blocking 0</code><br>
      <code>attr tahoma1 room tahoma</code><br>
      <br>
      <br>Automatic created device e.g.:<br>
      <code>define tahoma_23234545 tahoma DEVICE io://0234-5678-9012/23234545</code><br>
      <code>attr tahoma_23234545 IODev tahoma1</code><br>
      <code>attr tahoma_23234545 alias RollerShutter Badezimmer</code><br>
      <code>attr tahoma_23234545 room tahoma</code><br>
      <code>attr tahoma_23234545 webCmd dim</code><br>
      <br>
      <br>Automatic created place e.g.:<br>
      <code>define tahoma_abc12345 tahoma PLACE abc12345-0a23-0b45-0c67-d5e6f7a1b2c3</code><br>
      <code>attr tahoma_abc12345 IODev tahoma1</code><br>
      <code>attr tahoma_abc12345 alias room Wohnzimmer</code><br>
      <code>attr tahoma_abc12345 room tahoma</code><br>
      <br>
      <br>Automatic created scene e.g.:<br>
      <code>define tahoma_4ef30a23 tahoma SCENE 4ef30a23-0b45-0c67-d5e6-f7a1b2c32e3f</code><br>

      <code>attr tahoma_4ef30a23 alias scene Rolladen S&uuml;dfenster zu</code><br>
