I need to get an entry on my dashboard where you put in start and end times for a device

I was hoping this would be simple , but it turns out I’m simple.
I want a card on my dashboard that allows me to put in two times. This should tell a switch to turn on and turn off.
I have done this with with alexa but I want to get away from her so would prefer to open the companion app and put in e.g 1600 and 2200 on a card and it switches my gear on and off at those times.

help appreciated

Set up two Input Datetime helpers.

Create an automation with a Time trigger for each one, using the entity IDs of the above helpers in the at field.
