<h1 id="homematic-action">Homematic Action</h1>
<p>The Homematic action lets you send messages to a Homematic remote control with a display, currently the HM-RC-19-B (Radio remote control 19 button).</p>
<h2 id="prerequisites">Prerequisites</h2>
<p>The Homematic Binding (1.x) must be installed and configured.</p>
<h2 id="actions">Actions</h2>
<ul>
<li><code class="highlighter-rouge">sendHomematicDisplay(REMOTE_CONTROL_ADDRESS, TEXT)</code></li>
<li><code class="highlighter-rouge">sendHomematicDisplay(REMOTE_CONTROL_ADDRESS, TEXT, OPTIONS)</code></li>
</ul>
<p>The remote control display is limited to five characters; a longer text is truncated.</p>
<p>You have several additional options to control the display.</p>
<ul>
<li><code class="highlighter-rouge">BEEP</code> <em>(TONE1, TONE2, TONE3)</em> - let the remote control beep</li>
<li><code class="highlighter-rouge">BACKLIGHT</code> <em>(BACKLIGHT_ON, BLINK_SLOW, BLINK_FAST)</em> - control the display backlight</li>
<li><code class="highlighter-rouge">UNIT</code> <em>(PERCENT, WATT, CELSIUS, FAHRENHEIT)</em> - display one of these units</li>
<li><code class="highlighter-rouge">SYMBOL</code> <em>(BULB, SWITCH, WINDOW, DOOR, BLIND, SCENE, PHONE, BELL, CLOCK, ARROW_UP, ARROW_DOWN)</em> - display symbols, multiple symbols possible</li>
</ul>
<p>You can combine any option, they must be separated by a comma. If you specify more than one option for BEEP, BACKLIGHT and UNIT, only the first one is taken into account and all others are ignored. For SYMBOL you can specify multiple options.</p>
<h2 id="examples">Examples</h2>
<p>Show message TEST:</p>
<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sendHomematicDisplay("KEQ0012345", "TEST");
</code></pre></div></div>
<p>Show message TEXT, beep once and turn backlight on:</p>
<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sendHomematicDisplay("KEQ0012345", "TEXT", "TONE1, BACKLIGHT_ON");
</code></pre></div></div>
<p>Show message 15, beep once, turn backlight on and shows the Celsius unit:</p>
<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sendHomematicDisplay("KEQ0012345", "15", "TONE1, BACKLIGHT_ON, CELSIUS");
</code></pre></div></div>
<p>Show message ALARM, beep three times, let the backlight blink fast and shows a bell symbol:</p>
<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sendHomematicDisplay("KEQ0012345", "ALARM", "TONE3, BLINK_FAST, BELL");
</code></pre></div></div>
<p>Duplicate options (TONE3 is ignored, because TONE1 is specified previously):</p>
<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sendHomematicDisplay("KEQ0012345", "TEXT", "TONE1, BLINK_FAST, TONE3");
</code></pre></div></div>
