Cant get my first custom integration to work (took help from Chat GPT)


Would appriciate some helt with my first custom integration. I have programming experience but I’m new to HA and Python. So i tried to create the framework using ChatGPT (3.5 as 4 is not avalible), my thinking was to write the logic by my self after this.

What i try to accomplish is to read attributes from another sensor(Nordpool), make calculations and publish 2 states and a lot of attributes.

I have set “debug” state for this “energy_management” component in the log settings and when starting up i get the following errors in the log file:

2023-12-05 10:18:58.783 ERROR (MainThread) [homeassistant.setup] The energy_management integration does not support YAML setup, please remove it from your configuration

2023-12-05 10:18:58.783 ERROR (MainThread) [homeassistant.setup] Setup failed for custom integration energy_management: No setup or config entry setup function defined.

I have defined the custom component as a sensor and use async, is this the best setup?

I have done what i can with my very limited knowlege, would highly appriciate some guidence of how to proceed.

I added the following line in the configuration.yaml:

all looks weird to me :slight_smile: I would look at a basic integration or an existing cookie cutter template.

Many thanks fuatakgun for checking the code!

Clearly ChatGPT still has a lot to learn. I will do it the hard/normal way without shortcuts. I have made a development installation in Docker now and will start with the simple examples in the links you provided

Remember that the latest training data for ChatGPT is from September 2021. That is a very long time for the Python development and especially Home Assistant world :wink:
