Matrix theme netatmo home widget

Hi,

I’m new to this, but I have a problem. I can see my Netatmo in Paper UI but in my materix theme I can’t find it, have linked in in “Things” and “Items”. I use the original home widget. I change onley
from:

{{itemValue('Netatmo_Outdoor_Humidity') | number:0}} %
to:
{{itemValue('Outdoor_Humidity') | number:0}} %

have linked the natatmo to Outdoor_Humidity.
plz help me
