To interact with my coffee machine, I used HypeChatDemo, firstly because it uses the same technology and second, it’s pretty straightforward. You just need to install xcode or android studio and follow Hype-Labs github. They have a pretty clear and straight forward tutorial.

Make sure you insert the same app identifier and access token that you inserted in the ESP32 source code.

Now the better part is to check the results.

I made a couple of videos and turned them into funny GIFs.

Check the results here.

If you noticed, I’m asking for a coffee using Bluetooth, but you configured your ESP32 for WiFi.

I hope you have one of those fully automatic machines, this way you can just ask for the coffee and it’s done!
