Home assistant is logging warning regarding deprecated constant DEVICE_CLASS_OPENING:

Use BinarySensorDeviceClass.OPENING instead, please create a bug report at https://github.com/PiotrMachowski/Home-Assistant-custom-components-Froggy/issues

Would it be possible to replace it to BinarySensorDeviceClass.Opening? Seems like straight forward change.

Unfortunately in some places Google Maps is not showing accurate opening times, so this integration comes in handy :)
