I’ve used mosquitto MQTT with my pi for quite some time. Now that I have loaded HA via the all-in-one installation. Now when publishing to mqtt I get the following error message: Connection refused: not authorized. Error: The connection was refused…
Do I have to be in the venv to publish or subscribe to topics now that Homeassistant is running?
You do not. Sounds like a simple user/password error. I also run Mosquitto on the AiO install and it’s all working fine. Double check that the username and password in your config match the same in the mosquitto config file.
