[App][Pro] Mistral AI

Apps
1

Hi there!

I’ve been creating an app to use Mistral AI models directly on your flow cards

Setting up

  1. install the app on your Homey pro or SHS
  2. Go to mistral console (formerly “La Plateforme”) https://console.mistral.ai/
  3. activate your “experiment plan” (free) or paid plan
  4. create a new API key
  5. paste the API key in the homey app setting
  6. You’re all set :victory_hand:

Features

feature explanation use case recommended model
use Mistral LLM models you can use the “ask mistral model” to generate text create special notification or home summary mistral 8b for small tasks and notifications, Mistral Medium is usually enough for more complex tasks
use Mistral VLM models you can use the “ask mistral model with images” to generate text analyzing security camera snapshot Mistral Small 4, Pixtral is not recommended
use Mistral agent you can create various AI agents on Mistral platform, you can select a model, temperatures, tools, customs instruction. You can even ask the model to use a specific JSON format!
take action The homey app will prompt mistral API with a list of your devices and their capabilities, to act in your smart home according to your initial prompt create your own chatbot or with the new ask user homey notification Mistral Large is strongly recommended Medium and Small 4 should work fine too
conversation variable At the end of each flowcard you can add a custom variable if you want to keep the conversation to add a follow-up request chatbots or using another model for a secondary action

Disclaimer

  • many points of this app have been vibecoded and only then human supervised
  • If you use the free tier or “labs models” Mistral may use your request to train their models

Roadmap

Ask Home

Selecting whih devices are exposed to the AI and on which ones the AI has control
Better context and commands

Great!

It would be great to have a flowcard to upload a snapshot from a doorbel to mistral and get a discription back.

Is that possible?

Thx!

But also it will be soon possible to attach an image to one of your custom agent, it will allow you to ask the models to respond with your specific instruction and/or with a specific JSON format.

I could also create a spcific flowcard to analyze camera snapshot and return a description!

Hope this helps!

This works great!

Thanks!

I have another question: if you have multiple snapshots from different cameras described, how can you send the correct snapshot along with the answer?

In the Mistral AI vision flowcard, you can’t select the original picture.

So, the goal is to be able to read the Mistral response in, for example, a WhatsApp message and see the described image.

That would be absolutely amazing.

THX!

Hi @Thibaud_Lgs

Is the source code publicly available?

I am keen to learn, what MCP-API endpoints you have implemented. - Or does your App use the official Homey/Athom MCP Server?

Background:

I have a rather complex system prompt for Mistral based on the Homey/Athom MCP Server and tailored to my Homey system, that allows for complex status and event reports. It would therefore be interesting to see if that can be applied through your app as well and what has to be eventually changed.

[EDIT] Works well. Found code on Github.

[EDIT #2] Does not work. - Checked with test and live app version. Uninstalled, reinstalled, restarted (the usual dance).
Mistral modell selection seems not to work.
AI has no access to any device.
See 4a023115-f058-4843-9e2a-f0e9202efa6d
I have a Mistral pro account and the API key is valid and active.

Would be cool if you could have a look.
