Ok, I have noticed something with MQTT messages and turning machines on/off and have some questions.
I am making new flows that send/receive MQTT messages. Some messages need to be retained and some don't.
Some need QOS 0. Others 1 and some QOS 2.
But I'm guessing that it isn't that simple. Or: Is that simple and I am trying to get too much from it.
Or something like that.
So, I am making flows and while making them, I inject test message to see how things happen.
All good, I don't worry any more.
But it is becoming annoying that every time I turn this machine on and go to edit the flows, all those test injections are still there.
Can I have some channels not retained and others retained?
All with one server/broker.
