I am new to home automation world, and I am trying to get my head around how does stringify triggers the flow that starts from a sensor status change?
For example, if I create a flow to do a series of things when the door sensor change from close to open. The door sensor is connected to SmartThings (ST) Hub and is synced with Stringify.
How does stringify monitor the status of such door sensor?
Does my mobile phone app regularly checks in ST and ask for the current status?
Or does ST tell stringify when the door status is changed?
