how to store value as integer on Firebase? the value to store always became string although i set it to integer at Firebase first.
That’s no problem. On call back you can use a math multiply block to multiply the “string” by 1 to convert it to a number
but the firebase will get back the value from piezoelectric sensor with integer data type. is that not a problem?
You have to try it and see. This is how firebase component works. Otherwise in order to send “numbers” you have to use web component and Firebase Database REST API
how to do that?
