Does anyone know how to add google weather card in dashboard?
I want to see the rain probability per hour, just like the google card below, shown when you search for city_name + rain.
There are several ‘custom’ cards (not google though) that could help but it all depends on which source you have and how the attribs are presented. Example:
hacf-fr/lovelace-meteofrance-weather-card: 
Carte Lovelace dédiée à l’intégration Météo-France pour Home Assistant. (github.com)
It does show french but you could also use the one it was forked from. The attribs are in english so if you are not too shy in programming, it is quite easy to adapt the two javascripts.
