Hi all!
Trying to use MQTT Hub to integrate in Node-RED using the Homie-Convention Node.
The problem I encounter, also expressed from the developer is this Node-Red Homie Convention Node relies on the mqtt broker as a persistent database i.e the MQTT messages should be set as retained. Link to Node-RED forum topic
I use the Homey MQTT Broker app, and It may be there the problem is since I read the MQTT Hub send retained messages, anyone who can guide me?
According to the homie convention:
The nature of the Homie convention makes it safe about duplicate messages, so the recommended QoS for reliability is QoS 1 . All messages MUST be sent as retained , UNLESS stated otherwise
I interpret that if the device can’t do it the broker needs to handle it. Storing and saving QoS=0 Messages with retained flag is within the MQTT spec 3.3(?). The broker even should keep those messages. My question is if the Homey MQTT Broker capable of doing that?
