<p>The <code class="highlighter-rouge">sma</code> sensor will poll a [SMA][http://www.sma-america.com/] solar inverter and present the values as sensors (or attributes of sensors) in Home Assistant.</p>
<p>To enable this sensor, add the following lines to your <code class="highlighter-rouge">configuration.yaml</code> file:</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml entry</span>
<span class="s">sensor sma</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">platform</span><span class="pi">:</span> <span class="s">sma</span>
<span class="s">host</span><span class="pi">:</span> <span class="s">192.168.88.199</span>
<span class="s">password</span><span class="pi">:</span> <span class="kt">!secret</span> <span class="s">sma_password</span>
<span class="s">sensors</span><span class="pi">:</span>
<span class="s">current_consumption</span><span class="pi">:</span> <span class="pi">[</span><span class="nv">total_consumption</span><span class="pi">]</span>
<span class="s">current_power</span><span class="pi">:</span>
<span class="s">total_yield</span><span class="pi">:</span>
</code></pre>
</div>
<p>Configuration variables:</p>
<ul>
<li><strong>host</strong> (<em>Required</em>): The IP address of the SMA WebConnect module.</li>
<li><strong>password</strong> (<em>Required</em>): The password of the SMA WebConnect module.</li>
<li><strong>group</strong> (<em>Optional</em>): The user group, which can be either <code class="highlighter-rouge">user</code> (the default) or <code class="highlighter-rouge">installer</code>.</li>
<li><strong>sensors</strong> (<em>Required</em>): A dictionary of sensors that will be added. The value of the dictionary can include sensor names that will be shown as attributes.</li>
<li><strong>custom</strong> (<em>Optional</em>): A dictionary of custom sensor key values and units</li>
</ul>
<p>Sensors configuration:</p>
<p>The sensors can be any one of the following:</p>
<ul>
<li>current_power</li>
<li>current_consumption</li>
<li>total_power</li>
<li>total_consumption</li>
</ul>
<p>You can create composite sensors, where the sub-sensors will be attributes of the main sensor, e.g.</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code> <span class="s">sensors</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">current_power</span><span class="pi">:</span> <span class="pi">[</span><span class="nv">total_power</span><span class="pi">,</span> <span class="nv">total_consumption</span><span class="pi">]</span>
</code></pre>
</div>
<p>The SMA WebConnect module supports a wide variety of sensors, and not all these have been mapped to standard sensors. Custom sensors can be defined by using the <code class="highlighter-rouge">custom</code> section of the configuration. You will need: A sensor name (no spaces), the SMA sensor key and the unit</p>
<p>Example:</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code> <span class="s">custom</span><span class="pi">:</span>
<span class="s">yesterday_consumption</span><span class="pi">:</span>
<span class="s">key</span><span class="pi">:</span> <span class="s">6400_00543A01</span>
<span class="s">unit</span><span class="pi">:</span> <span class="s">W</span>
</code></pre>
</div>
<p>Over time more sensors will be added as standard sensors to the <a href="https://github.com/kellerza/pysma/blob/master/pysma/__init__.py#L18">pysma library</a>. Feel free to submit additional sensors on that repository.</p>
