  <h3>Properties</h3>
  <dl class="message-properties">
    <dt>RPC Server</dt>
    <dd>
      The connection to your EdgePi's RPC Server. Use <strong>Local</strong> if
      node-red is running on EdgePi. Otherwise use the
      <strong>Network</strong> option and enter EdgePi's IP address / Hostname.
