That's excellent, thanks! I'm using a Node-RED function to change the topic name. That works for me until the fix is released.

I am able to subscribe to the topic with the trailing slash and see the messages coming from HA (using mosquitto_sub), so there's no problem reaching the broker. The gateway itself doesn't seem to subscribe to that topic pattern as nothing is shown in debug mode.

Gateway does nothing:

mosquitto_pub -t 'mysensors-in/1/0/1/0/2/' -m '1'

Gateway converts message topic/payload into MySensors Serial protocol and the node receives it:

mosquitto_pub -t 'mysensors-in/1/0/1/0/2' -m '1'

Hi,

My node topics from the MQTT gateway doesn't contain trailing slashes, but their response topics published by HA do:

INFO:homeassistant.core:Bus:Handling <Event mqtt_message_received[L]: qos=0, topic=mysensors-out/1/0/2/0/2, payload=>
INFO:homeassistant.core:Bus:Handling <Event call_service[L]: service=publish, service_call_id=1977438992-1001, service_data=qos=0, topic=mysensors-in/1/0/1/0/2/, retain=True, payload=0, domain=mqtt>

The MQTT gateway doesn't forward these trailing slash topics to any nodes. When I manually (mosquitto_pub) publish to a "corrected" topic, my node receives the message.

My MySensors gateway is Raspberry Pi based, built from the development branch.
HA is the latest release.

Please help!
Thanks!!
