Switcher V4 integration and Lovelace

Hello Guys,
i would love to get your help and the Devs help here with something, long story short, i just bought a water heater switch (Switcher V4) which i found the integration for it, the problem is that its very limited,
also, i have a Service called switcher_kis.turn_on_with_timer but i cant use it in the lovelace card.

this is the lovelace card from some devs that created it for Switcher V2, but there is no support for it anymore and it doesnt work with V4
as you can see, there is an option of Timer in the card

can you guys help setting this up please ?
