Overnight, things have started working - see screenshots below. I had to start a new chat though - continuing in the last chat did not work. First impression: it is not very fast - but definitely with very high potential! ![Screenshot 2025-11-07 at 09.20.10](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/6/36e3d671905aaeb9f68ad983fc86d4cf5711ed6f.png) ![Screenshot 2025-11-07 at 09.20.32](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/d/7d1b76dc8aa43573b3460061e6d51e46a9c77e22.png) ---

Throwing this in here although it’s not GhatGPT. does anyone know how to get in touch with the homey developers on this? I’m trying to integrate Homey to an AI agent with MCP and the agent continuously failed. testing in Postman there’s something wrong with how it responds. Chatting with a developer he pointed out that there are different methods of implementing MCP and this might be the reason that homey may or may not have used the standard “MCP-standard”. ![Screenshot 2025-11-07 at 14.11.26](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/3/c3d8a1c8146cdb7ba44fc9c0d481730f68343bc0.png) ---

Using [`@modelcontextprotocol/inspector`](https://github.com/modelcontextprotocol/inspector), it seems to work fine for me: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/1/9163ff04f2566e08fdd8869ec6672da44c360bd8.png) ---

Any messages or input you got there that we can compare? Postman should work just the same ---

If it works for you all maybe there’s something I’m doing wrong somewhere…. Have you encountered any setting you need to activate? I noticed that when I set up the OAuth it did open the pop up and ask me to select the homey I wanted to use so it obviously did get some info… I notice my URL is built with language, is it the same for you: homey.app/en-fi/?utm\_source=mcp", ---

@Lars_Kristian_Haga did you use postman? could you share the message you got? ---

Works now. First impression: Slow. Second impression: When chatting at first, I had And have to convince ChatGPT voice assistant to use MCP to access my home. Which it said it did, then made up values and rooms in my house. Then, via text chat, I reminded it again that it has access via MCP. It was able to change the lighting, but only after confirming this big warning ![Skjermbilde 2025-11-07 kl. 20.52.15](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/d/8d534022df5cd2cf8048872abb9f08472e121fc5.png) ---

Wworks like a charm here, didn’t even know I have 220 active devices ! Showed me the whole status of the home. ![IMG_7295](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/a/1a2a7ed9b0fc4e047d7381f284df19f33e646004.jpeg) ---

Yesterday I have successfully connected and everything worked fine. If now try to list the device within ChatGPT it tells me that it can’t connect and gets an error “We couldn’t connect your account. Please try again”. The same error that I get if try to reconnect the Homey-Plugin [Previous page](https://community.homey.app/t/chatgpt-mcp-integration-fails/145001.md?page=1)
