It requires no configuration (zero-configuration) and uses the same programming interfaces, packet formats and operational semantics as unicast Domain Name System (DNS).</p> <p>It was designed to work as either a standalone protocol or alongside standard DNS servers. mDNS can work together with DNS Service Discovery (DNS-SD), a complementary zero-configuration networking technique specified separately in RFC 6763.</p> <br clear="left"/>http://luispa.com/en/posts/2024-12-21-ha-tplink/Sat, 21 Dec 2024 00:00:00 +0000http://luispa.com/en/posts/2024-12-21-ha-tplink/<img src="http://luispa.com/img/posts/logo-hass-switch.svg" alt="HA Switch Logo" width="150px" style="float:left; padding-right:25px" /> <p>In this post I explain how to control a PoE port on a TP-Link switch (<code>TL-SG108PE</code>) from Home Assistant. Since these small switches don&rsquo;t support <code>SNMP</code>, I&rsquo;ll use <code>curl</code> to authenticate, turn on, turn off or query the status of a specific port. The use case is being able to turn on or off a ReoLink PoE camera connected to one of the ports from Home Assistant.</p> <br clear="left"/>
