Date & Timestamp of when each Device is first added (included)

**Is your feature request related to a problem? Please describe.** When we have a large enviro, it is very difficult to find devices we just added, or if we are troubleshooting 'lost' devices in Home Assistant, find what devices they are based on when they are added. **Describe the solution you'd like** Please add a time stamp field to that captures Date & Timestamp of when each Device is first added (included) into the system. **Describe alternatives you've considered** I know no way to do this today
