I'm working with some IoT projects and for handling all data I have used Blynk application but now I have created my own app but problem is that I want to add sensor data to firebase, but I have multiple users that's why I want to separate my data for every user, how can i do this, which Library is helpful for this? I have searched on Google for this, but everyone adding data in common database but how to separate the data for multiple users?
To separate data per user in your database, you will want to organize the database reference path to a location relevant to the user uid. if your app supports Auth, you can access this with the currentUser object which should have their uid as a property.
