<h1 id="google-calendar-scheduler">Google Calendar Scheduler</h1>

<p>The Google Calendar Scheduler allows you to control items in openHAB at scheduled times in the future.  It will send commands to items or update the state of items when defined on one of your Google Calendars.</p>

<p>An additional persistence service, the Google Calendar Presence Simulator, writes item state changes as events on the calendar that will occur again some number of days in the future, to simulate your activity at home (such as turning lights on and off) when on vacation.</p>

<h2 id="obtaining-credentials">Obtaining Credentials</h2>

<p>Before you can integrate this service with your Google Calendar, you must have a Google API Console project.</p>

<ul>
  <li>Login to your <a href="https://console.developers.google.com">Google API Manager</a>.</li>
  <li>From the project drop-down, select an existing project or create a new one by selecting <strong>Create project</strong>.</li>
  <li>In the sidebar under “API Manager”, select Credentials, then select the OAuth consent screen tab.</li>
  <li>Choose an <strong>Email Address</strong>, specify a <strong>Product Name</strong>, and press Save.</li>
  <li>In the Credentials tab, select the Create credentials drop-down list, and choose <strong>OAuth client ID</strong>.</li>
  <li>Under <strong>Application type</strong>, select <strong>Other</strong>.</li>
  <li>Put <strong>Name</strong> and press the <strong>Create</strong> button.</li>
  <li>Copy <strong>client id</strong> and <strong>client secret</strong></li>
</ul>

<h2 id="service-configuration">Service Configuration</h2>

<p>After the first start, you need to authorize openHAB to allow use your calendar. Follow the instructions that appear in the openHAB log.  At the <code class="highlighter-rouge">openhab&gt;</code> prompt, enter <code class="highlighter-rouge">log:tail</code>, or at the shell prompt enter <code class="highlighter-rouge">tail -f /path/to/your/openhab.log</code>.</p>

  <p>If you later change your <code class="highlighter-rouge">client_id</code> and <code class="highlighter-rouge">client_secret</code> in the configuration, you will have to locate and delete the file <code class="highlighter-rouge">gcal_oauth2_token</code>, and stop and restart the service.  This is because the Google Calendar Scheduler does not detect that the OAuth token is no longer valid.  On openHAB 2.0.0 installed via <code class="highlighter-rouge">apt-get</code>, this file is located in the directory <code class="highlighter-rouge">/var/lib/openhab2/gcal</code>.</p>
</blockquote>

<h2 id="calendar-event-configuration">Calendar Event Configuration</h2>

<p>When creating or modifying an event on the calendar, its title can be anything, and its event description must contain the instructions in the following format:</p>

<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>start {
  send|update &lt;item&gt; &lt;state&gt;
}
end {
  send|update &lt;item&gt; &lt;state&gt;
}
</code></pre></div></div>

<p>or just</p>

<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>send|update &lt;item&gt; &lt;state&gt;
</code></pre></div></div>

<p>The commands in the <code class="highlighter-rouge">start</code> section will be executed at the event start time and the <code class="highlighter-rouge">end</code> section at the event end time. If these sections are not present, the commands will be executed at the event start time.</p>

<p>As a result, your lines in a calendar event might look like this:</p>

<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>start {
  send Light_Garden ON
  send Pump_Garden ON
}
end {
  send Light_Garden OFF
  send Pump_Garden OFF
}
</code></pre></div></div>

<p>or just:</p>

<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>send Light_Garden ON
send Pump_Garden ON
</code></pre></div></div>

<p>If the event description is entirely blank, then the event’s start and end times are used to exclude that time period from processing.</p>

<blockquote>
  <p>:warning: The calendar must not contain any events that do not conform to the above description, including public holidays, birthdays, any all-day events at all, personal calendar entries, etc.  It is recommended that you create a Google Calendar that is dedicated to the use of the Google Calendar Scheduler service.  Alternatively, careful use of the <code class="highlighter-rouge">filter</code> configuration parameter can be used to select only a subset of matching events on the calendar.</p>
</blockquote>

<h2 id="presence-simulation">Presence Simulation</h2>

<p>The Google Calendar Presence Simulator is an openHAB Persistence service can be used to realize a simple but effective presence simulation feature (thanks Ralf for providing the concept). Every single change of an item that belongs to a certain group is posted as new calendar entry in the future. By default each entry is posted with an offset of 14 days (If you’d like to change the offset please change the parameter <code class="highlighter-rouge">offset</code> in your <code class="highlighter-rouge">services/gcal-persistence.cfg</code> file). Each calendar entry looks like the following:</p>

<ul>
  <li>title: <code class="highlighter-rouge">[PresenceSimulation] &lt;itemname&gt;</code></li>
  <li>content: <code class="highlighter-rouge">send &lt;itemname&gt; &lt;value&gt;</code></li>
</ul>

<p>To make use of Presence Simulation you have to walk through these configuration steps:</p>

<ul>
  <li>configure the gcal-persistence bundle by adding the appropriate configuration. You must add only calendar_name. If you want to use your primary calendar just use the keyword <code class="highlighter-rouge">primary</code>. All other credentials are shared from Google Calendar Scheduler configuration.</li>
  <li>make sure your items file contains items that belong to the group <code class="highlighter-rouge">G_PresenceSimulation</code> - if you would like to change the group name, change it in <code class="highlighter-rouge">persistence/gcal.persist</code>.</li>
  <li>make sure one of your items files contains an item called <code class="highlighter-rouge">PresenceSimulation</code>.  If you would like to change the group name please change the parameter <code class="highlighter-rouge">executescript</code> in your <code class="highlighter-rouge">services/gcal-persistence.cfg</code> file.</li>
  <li>make sure the referenced Google Calendar is writeable by the given user at google.com.</li>
</ul>

<p>Note: you also need to configure the Google Calendar Scheduler to be able to read the entries from the calendar and act on them.</p>

<p>To activate the Presence Simulation simply set <code class="highlighter-rouge">PresenceSimulation</code> to <code class="highlighter-rouge">ON</code> and the already downloaded events are being executed. Items in your smart home will then behave like they did 14 days earlier.</p>

<p>A sample <code class="highlighter-rouge">persist/gcal.persist</code> file looks like this:</p>

<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>Strategies {
	default = everyChange
}

Items {
	G_PresenceSimulation* : strategy = everyChange
}
</code></pre></div></div>

<h3 id="solving-google-calendar-presence-simulation-errors">Solving Google Calendar Presence Simulation errors</h3>

<p>To solve any issues with any service bundle, increase the logging. At the <code class="highlighter-rouge">openhab&gt;</code> prompt you can enter:</p>

<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>log:set TRACE org.openhab.persistence.gcal
log:set TRACE org.openhab.io.gcal
</code></pre></div></div>

<p>You can later return them to <code class="highlighter-rouge">DEFAULT</code> or <code class="highlighter-rouge">INFO</code> level.</p>

<ul>
  <li>
    <p>“GCal PresenceSimulation Service isn’t initialized properly! No entries will be uploaded to your Google Calendar”</p>

    <p>The persistence configuration is not correct; check that the <code class="highlighter-rouge">client_id</code> and <code class="highlighter-rouge">client_secret</code> are correct in the gcal configuration.</p>
  </li>
  <li>
    <p>“creating a new calendar entry throws an exception: Forbidden”</p>

    <p>This can have several causes:</p>

    <ul>
      <li>
        <p>The <code class="highlighter-rouge">client_id</code> or <code class="highlighter-rouge">client_secret</code> might not be correct.</p>
      </li>
      <li>
        <p>The calendar name is not correct.</p>
      </li>
      <li>
        <p>If your not using your own calendar, make sure the sharing settings are correct and the user has sufficient rights to create calendar entries.</p>
      </li>
    </ul>
  </li>
</ul>
