Writing values to Firebase using MIT App Inventor

[rajsingh]

I am trying to write values from MIT App Inventor to firebase.
I referred to this tutorial: https://rominirani.com/tutorial-mit-app-inventor-firebase-4be95051c325
My block diagram:

Output when I wrote the value 0 to the database:

Why is the value being displayed like this? How do I display only 0?
Desired Output:
Control: 0
Status: 0

[TIMAI2]

AI2 presents the data to firebase like this: "\"0\"" in order to be able to return the data correctly to AI2 for text and lists. When you call back the data, you will just get 0.

If you really must write data to Firebase without these characters, then you can use the REST api and web component

Firebase Database and Storage: with the Web Component - Secure Rules

[fb] This is one of those, could it be done.... did I need to use the built-in firebase component, or the extensions available, in order to use Firebase database and storage, and operate secure rules. Well after some research and testing, it turns out that it could be done. Find out how: Firebase with a Web Component . . . My thanks @ChrisWard for proof reading and suggestions [EDIT - Now updated to include the new PATCH feature of the web component]
