I have two motion sensors in different zones. I require both to be inactive for a given period, say 5 minutes, then turn off some lights. I have tried the community app, which will combine the sensors, but there is no inactive card.
I read this as two inactive zones, waiting for 20 min. What would you expect to happen if the zone became active again? Would they not switch off in 20 mins? Albeit, they would come on again if the zone were active.
Make a copy of the sensors by using two virtual devices.Put these 2 virtual devices in a new zone and use zone activity to switch on and off the light.
