Entity sensor.charger_temperature (<class 'custom_components.ocpp.sensor.ChargePointMetric'>) is using native unit of measurement 'None' which is not a valid unit for the device class ('temperature') it is using; expected one of ['K', '°F', '°C']; Please update your configuration if your entity is manually configured, otherwise create a bug report at https://github.com/lbbrhzn/ocpp/issues
