 +
 +For the folks still reading this thread, I’ve been using MQTT since 2018 and have never experienced the difficulties the OP has reported.
 +
 +My introduction to MQTT began when I wanted to add MQTT support to an old home automation system. In order to do that, I had to gain a sufficient understanding of MQTT’s operation to ensure success. The resulting MQTT converter has worked very reliably and predictably for nearly 3 years now.
 +
 +What the OP has experienced is anomalous. In my tests, using Developer Tools > Services > MQTT: Publish, to purge a retained message, does indeed work; the topic’s payload does not reappear as a retained message.
 +
 +  * Using MQTT Explorer, published a retained message to a new topic.
 +  * Using Developer Tools > Services > MQTT: Publish, published an empty string, as a retained message, to the topic .
 +  * Disconnected/reconnected MQTT Explorer and now the topic and its payload were no longer present (i.e. retained payload removed from the broker’s storage).
 +  * Restarted the MQTT Mosquitto Broker Add-On.
 +  * Disconnected/reconnected MQTT Explorer. Topic and its payload did not return and were truly purged from the broker’s storage.
 +  * Using Developer Tools > Services > MQTT: Publish, published a //non//-retained message to the previous topic.
 +  * In MQTT Explorer (already running) it displayed the topic and its payload (//not//  as a retained message).
 +
 +In short, everything worked as expected.
 +
 +The OP carried out a similar procedure but reported a different outcome, one where the topic always contains a retained message despite attempts to disable it.
 +
 +There have been reports of performance issues with the MQTT Mosquitto Broker Add-on version 5.1.1 and maybe (just maybe) this is one of its manifestations. I can’t say for sure because I still use version 5.1 and it runs flawlessly.
