Starting 1 flow with 3 Aqara mini switches


I would like to be able to start 1 specific flow (e.g. activate/deactivate the alarm) with 3 different Aqara Mini Switch buttons (depending on which door we enter/exit through).
What is the best way to achieve this? (I use Homey Pro, Aqara buttons, Heimdall)
Thanks in advance for your help !

Did you already buy the “advanced flows” option?
In advanced flow you can simply connect all 3 switches to the one action card.

If you did not buy it yet:
Create 4 flows:
Flow1 = your action flow

WHEN this flow is started
THEN list all your actions here

Flow 2, 3 and 4 are similar flows that trigger the action flow

WHEN switch1 is triggered
THEN start flow1

WHEN switch2 is triggered
THEN start flow1

WHEN switch3 is triggered
THEN start flow1

I dont use the heimdall app, it will probably be even easier using that app
