Is there a way to creat flows using the presence detection on Echo devices? For example, would love for it to turn on lights and keep them on while I’m in the room and turn them off when I leave.
You can run an Alexa routine on presence detection. If you add the Homey skill to Alexa, you can execute flows from within those routines.
The skill also brings all your Homey devices into Alexa which can be useful, but can also create duplicate devices if, for example, you use an Alexa skill and a Homey app to control a device. You cannot selectively import devices and deleting them makes them reappear later. So the only way to deal with them is to disable them.
