Hi, I am sending values ​​from 2 ESP8266 devices to the RealTime Firebase in this way:  
data sent by each individual device:

## Device 1: String uid = “0OaciqwPf1NXnNvHB2RnVrXek5L2”; //(ESP1) String path = “/UsersData/” + uid; Firebase.setString(firebaseData,uid + “/Level”, Level);

## Device 2 : String uid = “0OaciqwPf1NXnNvHB2RnVrXek5L2”; //(ESP2) String path = “/UsersData/” + uid; Firebase.setString(firebaseData,uid + “/Level”, Level);

## Rules di RealTime Database: { “rules”: { “.read”: “true”, “UsersData”: { “$uid”: { .write": “true” // “.write”: “auth.uid !== null” }}}}

The data is received perfectly on Firebase Realtime Database, as shown in the attached photo.  
When the user logs in, I store a variable with the command “set stored variable uid to ‘user id’” (where user id is the Firebase user ID).

The problem arises on Thunkable: if I create a variable with “initialize cloud variable Level”, I don’t receive any data, since the value should be preceded by the user’s uid to be able to read it correctly.

I would like to know if it is possible to create a “multiple” variable, for example:  
“initialize cloud variable stored variable uid / cloud variable Level”  
Like this, when I use the function:  
“when cloud variable stored variable uid / cloud variable Level initializes or changes”,  
I would receive the constantly updated value in the app.

I also tried the method shown in the attached photo N°2, where each device correctly receives its value, but only when I open the app.

Can anyone kindly give me a suggestion on how to fix the problem?

It’s best to keep all of this information in a single topic: [Help with getting value from Firebase RealTime](https://community.thunkable.com/t/help-with-getting-value-from-firebase-realtime/3487272)

Otherwise, it’s confusing to try and help you because some of the previous details and advice is not included here.

I recommend that you do not initialize cloud variables. Just use the `set cloud variable " "` and `cloud variable " "` blocks when using cloud variables so that you can set the path each time, such as UsersData/[stored variable uid]/Livello
