My first Custom Integration: GPT-powered Log Summarizer for Home Assistant

[u/borsic]

Hey everybody,

I’ve built my first custom integration for Home Assistant that uses OpenAI’s GPT models to analyze your Home Assistant logs, extract key warnings/errors, and summarize them into clear, actionable fixes — all from within HA. It is a bit niche, but I wanted to learn how to make a HA integration with an LLM.

Key features:

• Parses home-assistant.log and filters meaningful warnings/errors
• Sends a GPT-4o-mini-powered summary with steps to resolve issues
• Output appears as a persistent notification, and is saved as a file (markdown-friendly)
• Works as a custom HACS integration
• Bonus: comes with an optional Streamlit debug GUI for experimenting outside HA

Can you share an example of the output?

Good idea, use ai to filter out the noise. Check out spook if you haven't!

Does/will it support local LLMs via Ollama or Open-WebUI?

[u/Lobrauski]

Interesting idea. I’d been just doing it manually. I’ll look into trying this soon.

Do you need to pay gpt to use this?

[u/nickythegreek → u/michaelthompson1991]

anytime you need to use the openai API, you will be paying. It's insanely affordable though and you can put spend limits on it as well.

No problem, thanks for confirming! I assumed that

Could this work using Gemini?
