I would like to setup a flow where after everyone leaves, items are initiated - lights, heat, etc. I was trying to figure out how to initiate the flow, and was wondering if I could have each family member create a flow on their phones where when they leave, a variable is set for each individual. Then I could set a flow where when everyone leaves using their variable values to determine when the flow should initiate. Can this be done? Or am I overthinking and there is an easier way to accomplish Home members being away or home?
