Hi Roger,

Thank you so much for your advice. Using multiple topic is nice idea. I
think the design of the topic hierarchy is important for efficient
subscriber allocation in this case.

Best regards,

Takahiro

Hi Takahiro,

What you describe is unfortunately not something that MQTT supports.
All subscribers to a topic receive all messages. You could produce
similar behaviour by spreading your messages out over multiple topics
with one subscriber per topic, but it isn't really what you are after
I think.

Regards,

Roger
