LaMetric TIME (pre-2022)

Supported devices: LaMetric TIME. Limitations: The integration communicates with the LaMetric device over the local network. If the device is not reachable, its entities become unavailable.

The list of supported sounds is fixed by the device firmware. Adding custom sounds is not possible.
