Recently I was migrating from one pi to another. Wanted to phase this into steps, ie running all on new hw but connecting to old mqtt broker.
Documentation points to setting mqtt: in configuration.yaml
After half an hour of struggling, getting nothing but “authentication failed” in logs I decided to move everythig at once. Since it ddidn’t solve issue either, I found that mqtt broker credentials are set in mqtt Integration GUI.
Of course after entering proper credentials into GUI provided forms everything started to work.
Am I wrong saying that this part of documentation is outdated? It doesn’t even mention mqtt integration GUI.
Is setting mqtt in configuration.yaml still valid way for some cases? if so, then when?
