Those are the fingerprints of devices included in the ST-managed Edge drivers. Edge drivers are in beta, so you have the option of using them for your devices, with the understanding that you may run into bugs, or sticking with Groovy DTHs for now. Edge drivers have the benefit of running locally on your hub, which should mean faster execution and greater reliability. Troubleshooting them is a little more complicated right now, since their logs are only visible through the Command Line Interface (CLI) and don’t show on the Groovy IDE Live Logging page.
If you stick with Groovy, your devices will be automatically transitioned to Edge drivers when ST decides that it’s time to make the switch. If you want to use the Edge drivers now, the topic below has instructions for installing the ST drivers on your hub.
