Home Assistant with AI: giving an LLM admin rights to your home

A test connected Home Assistant to an LLM through HA-MCP and gave it admin rights over a flat. The verdict: creepy, and good at the same time.

Would you hand an AI chatbot the admin keys to your flat? A hands-on test of Home Assistant with an LLM did exactly that, using a tool called HA-MCP. The verdict fits in two words: creepy, and good.

What is HA-MCP for Home Assistant?

Home Assistant is the popular open-source smart home software that you run on your own hardware. An LLM, short for large language model, is the kind of AI that powers chatbots. HA-MCP links the two through MCP, a standard that lets AI models talk to other software.

With admin rights, the model is not limited to answering questions about your home. It gets broad access to the setup itself.

Is it a good idea to give an LLM admin rights?

That was the question behind the experiment, and the answer is not a plain yes or no. The test found the result useful, and also unsettling. Both reactions make sense. Admin access means wide access, so a lot of trust goes to a system that can misread an instruction.

For anyone who already runs Home Assistant and wonders whether an AI assistant belongs in the setup, the takeaway is practical: it can work well, but you should decide deliberately how much control it gets.
