WARNING AppDaemon: Unable to find widget type 'persistent_notification'

Hi
Trying to set up a standard dashboard for hassio using AppDeamon v4
Everything seems to work except the weather.weather widget.
I have Dark Sky set up in hassio. Can only see the following states in hassio

weather.dark_sky	partlycloudy	
temperature: 30.5
humidity: 71
ozone: 279.7
pressure: 1011.9
wind_bearing: 20
wind_speed: 8.58
visibility: 16.093
attribution: Powered by Dark Sky
forecast: [object Object],[object Object],...
friendly_name: Dark Skyh

Have tried multiple settings in main.dash file but seem to get this error in AppDeamon log:

Any ideas?

Thanks in advance!

It’s been a while since i used the dashboard, but i think you need the darksky sensor for the widget, not the weather integration.
It’s a little confusing because both show up as ‘weather’ in integrations.

EDIT: No clue about the persistent_notification warning.
