<script type="text/x-red" data-help-name="sunrise">
    <p>Uses the suncalc module to generate an output at sunrise and sunset based on a specified location.</p>
    <p>Several choices of definition of sunrise and sunset are available, see the <i><a href = "https://github.com/mourner/suncalc" target="_new">suncalc</a></i> module for details.</p>
    <p>The first output emits a <b>msg.payload</b> of <i>1</i> or <i>0</i> every minute depending if in between selected times or not.
    The second output emits only on the transition between night to day (<i>-> 1</i>) or day to night (<i>-> 0</i>).</p>
    <p>Also sets <b>msg.topic</b> to <i>sun</i> and <b>msg.moon</b> to the fraction of the moon between 0 and 1.</p>
