V2C Trydan EVSE integration add firmware as sensor

It would be very useful to have a sensor with the firmware of the V2C Trydan EVSE integration. Right now you can see it in the integration Device Info, but you cannot use it inside HASS in a card, for example.
Many thanks

Try using a template:

{{ device_attr('binary_sensor.trydan_ready', 'sw_version') }}

Go to:

Settings → Devices → Helpers → Create Helper → Template

choose “Template Sensor”

fill:
