The Scorchers struggled to make 9-124 at Junction Oval on Monday night before 37-year-old Devine captured 4-19, hitting the two-paced deck hard and taking the key wickets of Australia allrounder Annabel Sutherland (0) and England captain Charlie Dean (13).
Dean was brilliantly stumped by new Scorchers captain Beth Mooney when the Stars appeared in control at 4-79 before taking another slick catch standing up to the stumps as drizzle fell throughout the run chase.
"It was all about trying to get the ball on the stumps," player of the match Devine said.
"Moons probably made me look better than I was. It was a whole team effort which is what we really pride ourselves on."
When Stars captain Meg Lanning (41) fell to make it 5-79 the visitors were cock-a-hoop. Lanning was easily the best batter on either side.
Scorchers legspinner Alana King claimed a double-wicket maiden in the 18th over to finish with 3-17 in a class display as the Stars were bundled out for 109 in 18.1 overs.
Earlier, the Scorchers were cruising at 0-36 after the powerplay but the introduction of spin derailed them.
Stars and England wicketkeeper Amy Jones was brilliant and took two legside screamers among her four catches, enhancing her reputation as one of the game's best when standing up to the stumps.
Perth advanced to 2-70 but that soon became 7-76.
Left-arm orthodox bowler Sophie Day, offspinner Dean and legspinner Maisy Gibson brought variety and guile to their work to exploit the conditions to perfection.
Each picked up two wickets.
Perth opener Mooney, who has assumed the captaincy from long-serving skipper Devine, made 17.Â
That was only bettered by allrounder King (18) who was run out when unable to run after slamming a shot into her own foot.
