I was wondering if the WebThings Gateway has an addon which let you connect to the WebThings gateway via an external app created with for example the MIT App Inventor or Thunkabe.
I have already created a system where an app (created with the MIT App Inventor) could sent data to a database (in my case Google Firebase), this database would then sent the data to a microcontroller with build-in WiFi module (ESP8266).
I want to keep the data to myself instead of using a middleman.
That is why I want to recreate this system by replacing Google Firebase with the WebThings Gateway. But in order to do so, I need to find a way to connect the WebThings gateway to an external app. The communication between the gateway and the ESP is pretty much sorted using the ESPHome addon.
Does anyone know how I could manage this? Workarounds are also welcome!
