We currently cannot reliably send events to local devices (e.g. Wemo and TP-Link) when you depart, as you will have disconnected from your home network before the leave event actually occurs.
We also don't offer reliable support for multi-client location-based Routines. If you have Yonomi installed on multiple devices, or multiple members of your family are logged into your Yonomi account, geofence-based events may not work properly.
