I am using Home Assistant Supervised on a Pi3B +.
I installed the MQTT add-on.
I have another Raspberry and would like to send data via MQTT to Home Assistant but … it doesn’t work.
1- Is the MQTT add-on a broker accessible from “outside”?
2- The IP address of my Home Assistant is 192.168.1.150, does the broker also have this address?
3- A solution?
First, I’d check with a tool like MQTT Explorer on your desktop whether you can connect to the broker or not.
Second, when you try to publish a message, do you use username and password?
Ok, I use MQTT Explorer and it’s working with a username and a password.
Question : Is it possible to change the password? I’ve an auto-generated password and it’s very long.
PS : OpenZwave is working, I presume that if I change the password, I must re configure OpenZwave?
