<p>Integrates MySensors lights into Home Assistant. See the <a href="/components/mysensors/">main component</a> for configuration instructions.</p>
<p>The following actuator types are supported:</p>
<h5>MySensors version 1.4</h5>
<table>
<thead>
<tr>
<th>S_TYPE</th>
<th>V_TYPE</th>
</tr>
</thead>
<tbody>
<tr>
<td>S_DIMMER</td>
<td>V_DIMMER*, V_LIGHT*</td>
</tr>
</tbody>
</table>
<h5>MySensors version 1.5 and higher</h5>
<table>
<thead>
<tr>
<th>S_TYPE</th>
<th>V_TYPE</th>
</tr>
</thead>
<tbody>
<tr>
<td>S_DIMMER</td>
<td>[V_DIMMER* or V_PERCENTAGE*], [V_LIGHT* or V_STATUS*]</td>
</tr>
<tr>
<td>S_RGB_LIGHT</td>
<td>V_RGB*, [V_LIGHT* or V_STATUS*], [V_DIMMER or V_PERCENTAGE]</td>
</tr>
</tbody>
</table>
<p>V_TYPES with a star (*) denotes required V_TYPES. Use either V_LIGHT or V_STATUS and either V_DIMMER or V_PERCENTAGE for an applicable actuator.</p>
