Problem with lovelace card generation

[Palpyroth]

Hello,
I'm a noob in HA but I want to do 2 weather cards like

and the same but hourly.

When I follow the readme I've this result

I miss forecast low temp and precipitation

type: custom:weather-chart-card
entity: weather.openweathermap
show_main: true
show_attributes: true

I try to change entity but the only weather entity I've is openweathermap (cant use sensor entity)
Can someone healp me?

thank you

Hourly forecast does not provide low temp.
