<h3>Robonect</h3>
<ul>
<p>Robonect is a after-market wifi-module for robomowers based on the husky G3-control. It was developed by Fabian H. and can be optained at www.robonect.de. This module gives you access to the basic commands. This module will not work without libjson-perl! Do not forget to install it first!</p>

  <p><a name="RobonectDefine"></a> <b>Define</b></p>
  <ul>
    <code>define &lt;name&gt; Robonect &lt;ip-adress or name&gt;</code>
    
	<p>Setting Winterschlaf prevents communicating with the mower.</p>
	
	<p>The authentication can be supplied in the definition as plaine text or in a differen way - see the attributes. Per default the status is polled every 90s.</p>

    <p>Example:</p>
      <pre>
      define myMower Robonect 192.168.13.5
	  define myMower Robonect myMowersDNSName
      </pre>
  </ul>
  
  <p><a name="RobonectSet"></a> <b>Set</b></p>
  <ul>
	<b>Set</b>
	<ul>
		<li>auto<br>
			Sets the mower to automatic mode. The mower follows the internal timer, until another mode is chosen. The mower can be stopped with stop at any time. After using stop: be aware, that it continues 
			mowing only if the timer supplies an active slot AND start is executed before.
		</li>
		<li>manuell<br>
			This sets the mower to manual mode. The internal timer is ignored. Mowing starts with start and ends with stop.
		</li>
		<li>home<br>
			This sends the mower directly home. Until you switch to auto or manuell, no further mowing work is done.
		</li>	
		<li>feierabend<br>
			This sends the mower home for the rest of the actual timeslot. At the next active timeslot mowing is continued automatically.
		</li>	
		<li>start<br>
			Start mowing in manual mode or in automatic mode at active timer-slot.
		</li>	
		<li>stop<br>
			Stops mowing immediately. The mower does not drive home. It stands there, until battery is empty. Use with care!
		</li>	
		<li>maehauftrag<br>
			This command starts a single mowing-task. It can be applied as much parameters as you want. For example you can influence start-/stop-time and duration.<br>
			The parameters have to be named according the robonect-API (no doublechecking!).<br>
			<br>
			Example:<br>
			Lauch at 15:00, Duration 120 minutes, do not use a remote-start-point, do not change mode after finishing task
			<pre>
			  set myMower maehauftrag start=15:00 duration=120 remotestart=0 after=4
			</pre>			
		</li>
		<li>winterschlaf &lt;on, off&gt;<br>
			If set to on, no polling is executet. Please use this during winter.
		</li>	
		<li>user &ltuser&gt;<br>
			One alternative to store authentication: username for robonect-logon is stored in FhemUtils or database (not encrypted).<br
			If set, the attributes regarding authentication are ignored.
		</li>		
		<li>password &lt;password&gt;<br>
			One alternative to store authentication: password for robonect-logon is stored in FhemUtils or database (not encrypted).<br
			If set, the attributes regarding authentication are ignored.
		</li>
	</ul>
  </ul>

  <p><a name="RobonectGet"></a> <b>Get</b></p>
  <ul>
	<b>Get</b>
	<ul>  
		<li>status<br>
			Gets the actual state of the mower - normally not needed, because the status is polled cyclic.
		</li>
		<li>health<br>
			This one gets more detailed information - like voltages and temperatures. It is NOT SUPPORTED BY ALL MOWERS!!!<br>
			If enabled via attribute, health is polled accordingly status.
		</li>

  <p><a name="RobonectCredentials"></a> <b>credentials</b></p>
  <ul> 
    If you supply a valid path to a credentials file, this combination is used to log in at robonect. This mechism overrules basicAuth.
  </ul> 

  <p><a name="RobonectBasicAuth"></a> <b>basicAuth</b></p>
  <ul> 
	You can supply username and password plain or base-64-encoded. For a base64-encoder, use google.
      <p>Example:</p>
      <pre>
      define myMower Robonect 192.168.5.1
	  attr myMower basicAuth me:mySecret
      </pre>    
	  <pre>
      define myMower Robonect 192.168.5.1
	  attr myMower basicAuth bWU6bXlTZWNyZXQ=
      </pre>    
  </ul>	

  <p><a name="RobonectPollInterval"></a> <b>pollInterval</b></p>
  <ul>
	Supplies the interval top poll the robonect in seconds. Per default 90s is set.
  </ul>
  
  <p><a name="RobonectTimeout"></a> <b>timeout</b></p>
  <ul>
	Timeout for httpData to recive data. Default is 4s.
  </ul>
  
  <p><a name="RobonectHealth"></a> <b>useHealth</b></p>
  <ul>
	If set to 1, the health-status of the mower will be polled. Be aware NOT ALL MOWERS ARE SUPPORTED!<br>
	Please refer to logfile or LAST_COMM_STATUS if the function does not seem to be working.

<p>Robonect ist ein Nachr&uml;stmodul f&uuml;r automower, die auf der Husky-G3-Steuerung basieren. Es wurde von Fabian H. entwickelt und kann unter www.robonect.de bezogen werden. Dieses Modul gibt Euch Zugriff auf die n&ouml;tigsten Kommandos. Dieses Modul ben&ouml;tigt libjson-perl. Bitte NICHT VERGESSEN zu installieren!</p>


  <p><a name="RobonectDefine"></a> <b>Define</b></p>
  <ul>
    <code>define &lt;name&gt; Robonect &lt;IP-Adresse oder Name&gt;</code>
    
	<p>Mit gesetztem Winterschlaf wird die Kommunikation zum M&auml;her unterbunden.</p>
	
	<p>Die Zugangsinformationen k&ouml;nnen im Klartext bei der Definition angegeben werden. Wahlweise auch per Attribut. Standardm&auml;&szlig;ig wird der Status vom RObonect alle 90s aktualisiert.</p>

    <p>Beispiel:</p>
      <pre>
      define myMower Robonect 192.168.13.5
	  define myMower Robonect myMowersDNSName
      </pre>
  </ul>
  
  <p><a name="RobonectSet"></a> <b>Set</b></p>
  <ul>
	<b>Set</b>
	<ul>
		<li>auto<br>
			Dies versetzt den M&auml;her in den Automatikmodus. Der M&auml;her reagiert nur auf den internen Timer, bis eine andere Betriebsart gew&auml;hlt wird. Der M&auml;her kann mit Stop jederzeit
			angehalten werden. Es wird erst wieder begonnen zu m&auml;hen, wenn der Timer (wieder) ein aktives Fenster hat UND Start gesendet wurde.
		</li>
		<li>manuell<br>
			Dies versetzt den M&auml;her in den manuellen modus. Der interne Timer wird nicht beachtet. Der M&auml;her reagiert nur auf Start oder Stopp Befehle von FHEM. 
		</li>
		<li>home<br>
			Dies schickt den M&auml;her direkt nach hause. Weiteres m&auml;hen wird verhindert, bis auf manuell oder auto umgeschalten wird.
		</li>	
		<li>feierabend<br>
			Dies schickt den M&auml;her f&uuml;r den aktuellen Timerslot direkt nach hause. Beim n&auml;chsten aktiven Timerslot wird weitergem&auml;ht.
		</li>	
		<li>start<br>
			Startet den M&auml;hvorgang im manuellen Modus oder im Automatikmodus bei aktivem Zeitslot.
		</li>	
		<li>stop<br>
			Beendet den M&auml;hvorgang. Der M&auml;her f&auml;hrt nicht nach Hause und beginnt nicht wieder zu m&auml;hen. Er bleibt stehen, bis die Batterie leer ist. Nur mit Bedacht benutzen!
		</li>	
		<li>maehauftrag<br>
			Hiermit wird ein (einmaliger) Auftrag an den M&auml;her abgesetzt. Es können beliebig viele Parameter mitgegeben werden. So kann zum Beispiel der Modus nach dem Auftrag,
			sowie Start- oder Stoppzeit beeinflusst werden.<br>
			Die Parameter m&uuml;ssen wie in der API des Robonect beschrieben lauten. Es erfolgt keine syntaktische Prüfung!<br>
			<br>
			Beispiel:<br>
			Startzeit 15 Uhr, Dauer 120 Minuten, keinen Fernstartpunkt verwenden, keine Betriebsartenumschaltung nach Auftragsende
			<pre>
			  set myMower maehauftrag start=15:00 duration=120 remotestart=0 after=4
			</pre>			
		</li>		
		<li>winterschlaf &lt;on, off&gt;<br>
			Wenn aktiviert, wird das Pollen unterbunden. Empfiehlt sich f&uuml;r die Winterpause.
		</li>	
		<li>user &ltuser&gt;<br>
			Alternativ zur Angabe per Argument kann per Set-Befehl der Benutzername zur Anmeldung am Robonect hier einmalig eingegeben werden. Er wird im Klartext in FhemUtils oder der DB gespeichert.<br>
			Wenn angegeben, werden die Attribute zur Authentisierung ignoriert.
		</li>		
		<li>password &lt;password&gt;<br>
			Alternativ zur Angabe per Argument kann per Set-Befehl das Passwort zur Anmeldung am Robonect hier einmalig eingegeben werden. Er wird im Klartext in FhemUtils oder der DB gespeichert.<br>
			Wenn angegeben, werden die Attribute zur Authentisierung ignoriert.
		</li>

  </ul>

  <p><a name="RobonectGet"></a> <b>Get</b></p>
  <ul>
	<b>Get</b>
	<ul>  
		<li>status<br>
			Holt den aktuellen Status des M&auml;hers. Wird normalerweise nicht ben&ouml;tigt, da automatisch gepolled wird.
		</li>
		<li>health<br>
			Mit diesem Kommando können detailliertere Informationen vom M&auml;her gelesen werden. Beispielsweise sind einge Spannungen und Umweltbedingungen verf&uuml;gbar.<br>
			Es werden NICHT ALLE M&Auml;HER UNTERST&Uuml;TZT!!!
			Wenn das entsprechende Attribut gesetzt ist, wird health analog status gepolled.
			This one gets more detailed information - like voltages and temperatures. It is NOT SUPPORTED BY ALL MOWERS!!!<br>
			If enabled via attribute, health is polled accordingly status.
