Nested firebase tag - with .datachanged

Hello Guys,
Well I have nested firebase as shown in picture

And the picture of my blocks:

The thing is that my temps are updating correctly, the problem is that the "REMOTE" is not updating, as you can see on the block picture, I have tried it in different way and it is not working at all.

I wish it to be uploaded anytime there is a change in state, I cannot shift this tag to main bucket.
I think if the data was updated, this tag should be updated as well, but it is not happening, what am I doing wrong ?

Welcome Piggy, I noticed the quotes in REMOTECNTRL/REMOTE. Shouldn't it be
grafik ?
