Input_time from car used in node red automation

Hi,
as a noob hoping someone smarter than me could point me in the right direction as cant find the answer from googling lots.

I am doing an irrigation setup. Its shaping up, but some way to go. In the front end in lovelace i have a card that someone enters the time (hour/min) to start the irrigation programme, but, cant figure out how to pick up that time in node red to start the automation at that time, has anyone done this?

Also, i want the front end lovelace cards per zone (10 zones) to have days of the week per zone to run, ie zone 1 might run mon/weds/fri and zone 2 might run tues/thurs. Is there a checkbox type setup for lovelace or would these all need to be input_booleans? And is the best way to do that 7 input_booleans per zone (70 booleans)? just wondered if there is a smarter way, as in node red would have to test against each 7 per zone to test to run, unless there is a smart way in node red to test against the 1/0 in some script, as again 10 zones, 70 booleans could make it complex.

hoping to be able to share this one setup, as its an b-hyve orbit setup, i have orbit integrated, i have the zone switches/status, i have booleans setup to “run or not run the automation” and then booleans to run/not run a zone, i have time inputs per zone to determine how long to run each zone programme for, and all that running lovely in node red, so happy to share all that, just like to get it working on user time input + days of week and then I think it will be very useful for anyone using orbit.

thanks
Darren

my lovelace and node red so far (just showing couple of zones, as once get it working for 2 its same process for 10). the node red works nicely, not starting 2nd zone until finished watering 1st zone, and if 1st zone doesnt run it moves straight to 2nd zone etc
