ImperiHome binding 2.0

Hello! I tried this with a couple of elements of temperature and humidity, and also add a graph. After adding a graph in the log many such lines:

is 3-6 for a second, is this normal?

Here and here there is a discussion about the binding of Google Home to the openHAB2. And it became possible, thanks to @MARZIMA. I do not have Google Home yet, but I’m following the events in this thread, I hope to buy Google Home in the near future and screw it to the openHAB2. If I understand correctly, then Google Home communication with openHAB2 is done through the tags of the itemes and they should only be from a specific list supported by Google.
@pdegeus your binding also uses tags. So these two bindings can not work in parallel with openHAB2? What if they need both? Or am I missing something?
Thanks!
