Our team currently has a database that can exchange results between the firebase realtime database and Arduino, and another firestore database that can exchange results with the React app. At this time, when Arduino transmits the result to the realtime database, I want to know how to read the value from firestore connected to the React app and transmit it to the React application.

arduino board wemos D1 R1.

I dont’ know what to do.

Is it better to work on a project by concentrating it on one computer?
