Victron and Node Red relay control

Complete coding newb here but looking to try to expand the victron systems I commonly use. Any node red experts here? Wondering if it is possible to create logic that combines the functions of both relays on the cerbo GX.
To make my gen auto start function how i’d like it needs 2 separate relays. Perfect world it would use the cerbo auto start function but only close relay 1 for a set amount of time (30 seconds maybe) to crank the gen, then close relay 2 once gen shut off criteria is met.

Sound plausible? ive taken a look at the node red flow chart option today for the first time and struggling to figure out how id make this happen.
