Probably since one of the last openHAB updates my log is flooded with the following message. I know it’s nothing serious, but it’s still pretty annoying. I’m running openHAB and Mosquitto on docker.

2025-04-12 15:29:14.582 [WARN ] [.incoming.MqttIncomingPublishService] - No publish flow registered for MqttStatefulPublish{stateless=MqttPublish{topic=wifistat, payload=67byte, qos=AT_MOST_ONCE, retain=false}, packetIdentifier=-1, dup=false, topicAlias=0, subscriptionIdentifiers=[]}.
2025-04-12 15:29:15.581 [WARN ] [.incoming.MqttIncomingPublishService] - No publish flow registered for MqttStatefulPublish{stateless=MqttPublish{topic=wifistat, payload=67byte, qos=AT_MOST_ONCE, retain=false}, packetIdentifier=-1, dup=false, topicAlias=0, subscriptionIdentifiers=[]}.

I don’t have an item called “wifistat”, and also can’t find anything related to “wifistat” if I monitor my Mosquitto with e.g. MQTT Studio.

This thread suggests restarts (which I’ve done) or Binding-re-installs (which I’m reluctant to do since everything works smoothly).

Does anyone have an idea how I can identify the source?

Update: Not sure if this or this means that it’s a bug?
