Mqtt auto discovery for Home Assistant

[Shadowpost]

After a number of hours fiddling, I managed to get the sketch working on my ESP8266 and I can recieve data from my weather station.
However, this is not formatted and in Home Assistant, I see it as a string of multiple values.

A solution would be a few lines of code that make the data visible for Home Assistant through MQTT auto discovery.

An alternative could be to edit the config.yaml, but I'm not sure how.

Any help will be appreciated!

Hi,

this makes sense. I found the following: https://www.home-assistant.io/integrations/mqtt/#mqtt-discovery
If you can provide a JSON file, I will take care of integrating it into the software.

Otherwise I will not take care of this topic anytime soon.

Thanks for responding!

I've spent the afternoon adding the sensors in configuration.yaml for each entity in the mqtt message.

This works now and it shows up in Home Assistant as 1 device with all the sensors.

I'm happy how this worked out. You don't need to integrate it for me in particular.
For future users, the auto-discovery would make this project a lot more user friendly. :)

Cheers!

Good job! May I ask you to share the configuration.yaml file here for others and maybe as a base for the auto discovery?

[Shadowpost]

Will do. May take a few days. ;)

Thanks for providing your configuration! The formatting has been lost by pasting it into the comment. May I ask you to add it again as an attachment or enclosed in three backticks (see https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#quoting-code)?

Bresser HA MQTT custom config.txt
I hope this works better. Adding a code directly here is pretty sh*tty...
