IOT WebApp with Firebase

I need a website that displays information from a firebase realtime database to each user registered in the website as appropriate. Each user must be assigned to a certain number of sensors (which are registered in the database based on their MAC address). In addition, it must have a configuration section, in which information must be sent to the database. - Firebase Authentication ==> Login/Register - Possibility to assign sensors to a certain registered user - Dashboard with graphs to show the info of each assigned sensor to the current user (Read data from firebase) - Configuration page to configure the device(Post data to firebase) The type and number of sensors that can be connected to each device varies, but they are temperature, humidity, light sensors, people counters, current, voltage and power meters. the structure of each sensor is attached in image. Each device has a unique address and each sensor also. Each devices is set to the directory "dispositivos", there in the directory "info" you will have all the sensors ID. In "payload" you will get every register (in the example there are only two, but they are going to be quite a lot!) of every sensor plus the battery level and timestamp. The part that posts the information from the sensors to the firebase is already developed but changes can be made if necessary.
