Hope it helps! :smile:
Thanks! :wink:

Doesn’t this call the database only once when the page opens?

This command is the one you should probably be using but I’m not sure I’m using it right in this example,it should, but you first have to add a listener to that specific key.

I never tried this so letme know if it works

I would suggest that you use cloud variables instead of the Realtime DB component. It uses Firebase (and your Firebase API key and URL, if you have them set in the your App Settings) behind the scenes but it is much easier to use. Here’s an example of how you might use them to do something when the tag has the value 5:


In this example ‘myVar’ is the Firebase key.

Hope this helps.
