Great explanation. I use MQTT regularly for home automation, and I love the "forgiveness" it gives with sometimes sketchy network connectivity, as well as the great way manufacturers are using it in a "sleep till I need to fire a simple update" technique that conserves battery life in remote devices that may not have mains power available.

These videos are amazing; very grateful to Walker (and team) and what he is leading. Note for Zac - probably "queue", not "que" for acronym of MQTT

Apparently MQTT no longer even stands for that. MQTT is MQTT now. But thank you!

Pls explain about how the subscriber know if the publisher is loss connection.

It publishes a death certificate. The connection is stateful (It knows if it's good or not)

Anyone understood the part around 10:57? How can you subscribe with an "outbound" connection?

@4.0Solutions 2 ай бұрын

The subscription response comes back through the connection established by the client through the outbound connection to the broker.
