[APP][Pro] Gemini AI - Control your Smart Home with Google's Gemini

This is the reason: if you are using free tier API keys, the only models light enough not to burn all your daily tokens with a smart home command are the 2.5 flash and the 2.5 flash-lite.

Change to 2.5 flash lite but now I get this

Try this: go to the app settings and in Configuration disable Google Search Grounding. Unfortunately, the 2.5 models don’t allow you to manage search and smart home management at the same time.

Okay but how can I make an advance flow? I can’t figure it out

The app has an action card that receives a command for your smart home (including creating an advanced flow), executes it, and returns Gemini’s response as a tag (for example, “I created an advanced flow with trigger xxxxx …”).
How you send the command to the action card is up to you: you can use the Telegram app or Homey’s free-text notification. Here’s an example of a flow using Telegram:

Alternatively, you can add the chat widget to the app’s home page and send commands to Gemini with it:

Remember, however, that Gemini’s free API keys are very limited and don’t allow for complex tasks like creating an advanced flow. For those, you must have an active billing account and use a more powerful model (at least 3.1).
