You can check what type of driver your device is using using the ST CLI or the API Browser+ from @TAustin. A device with show type DTH if it’s a Groovy based driver. Edge virtual devices should show type LAN.
While drivers run locally on your hub and routines that utilize local devices also do, programming your hubs behavior is done via the ST API which is hosted in the cloud and communicates to your hub over the Internet. So, if you lose your Internet connection, local automations can run autonomously, however, you won’t be able to use the APIs or the ST App to make changes to your environment until Internet is restored.
