[CDDMFlyer]

Hi, I am having trouble getting the home assistant discovery script working I get the below: and no discovery in HA? any ideas what I am doing wrong. I had it working on my last pi5, but I managed to destroy that one with a hosuing wate rleak.!!
Thanks in advance.

I believe that is just a "bad username or password" error.

Then this after running: source virtualenv/indi-allsky/bin/activate ./misc/home_assistant_auto_discovery.py
ConnectionResetError: [Errno 104] Connection reset by peer

I wonder if mosquitto is not running due to a port conflict. Can you run the following:

systemctl status mosquitto

[CDDMFlyer]

Aaron,
Looks like it is running. I restarted everyting around unchtime .

Anything wrong here?

[aaronwmorris]

I see the problem in the screenshot. You have "Use TLS" selected but using port 1883. The port for TLS would be 8883.

[CDDMFlyer]

wouldn't be something to do with move away from raspberrypi.local, to device name.local?

[CDDMFlyer]

Aaron, thanks couldn't get it to work with TLS on but turung it off and changing the port, and success. Hope all ok with tyou and thanks so much fo your ecellent support. What a fantsatic piece of coding...

Aaron, I am also having problems setting up mqtt for homessistant. I can post a new discussion if you prefer. I have a pi4 running indi-allsky and I run the ./misc/setup_mosquitto_mqtt.sh with success creating a username (indi-allsky) and password. I have installed homeassistant on different pi4 on the same network. When I try to setup the MQTT integration in HA i get an "Unknown error occurred". I enter the same credentials as I have in the indi-allsky config tab for MQTT. Alos , when I enter "mosquitto" into the command line i get the picture below. Am i battling to connect homeassistant because its not a client on the same machine as the indi-allsky software?
