your second setValue call is inside a class (your anonymous object), i suspect you meant to put it below it.

I solved, but not solved. Now I have a Logic ISSUE

I explain: As long as switch magnetic  remains scattered, the value of fcmotordoisb in the firebase must remain at 1

i suspect it’s an issue somewhere in your `Button` code, something not really kotlin related

+David Kirchner  I have 1 only more question. it's possible I solve issue of the my first screenshot, without changing that place code (fcmotordoisb.setValue(0))?

you could put it in an `init{}` block inside your `setOnButtonEventListener`, and then it’ll run on object creation. dunno how i feel about that code-style-wise. i think it’d be worth scouring stackoverflow for examples as folks suggested w/ their reactions, there’s going to be a fair number of opinions.
