<h3>Details</h3>
<p>The incoming json message is parsed if the <code>sid</code> matches the configured value for this device.</p>

<h3>Outputs</h3>

<p>Sample message:</p>
<p>
<pre>
{
   "fromip":"192.168.0.110:4321",
   "ip":"192.168.0.110",
   "port":4321,
   "payload":{
      "alarm" : 0,
      "density" : 0,
      "status" : "unknown",
      "time":1556989155457,
      "device":"smoke_detector",
      "sid":"158d0001107eb2",
      "model":"smoke"
   }
}
</pre>
</p>
<br>
Notes
<ul>
  <li>Alarm values are not all discovered. So far 0  = standby, 2  = alarm and 8 = low battery</li>
  <li>Status is set according to (known) alarm values</li>
  <li>The voltage does not seem to change. During testing this stayed at 3.205 even though the provided voltage to the detector was much less.
</ul>
</p>
