Hi !
My apologies for my poor English.
In the “Google Travel Time” integration, you can specify an arrival time, which is very useful for public transportation.
However, the date and time selection is fixed… not dynamic; you can’t choose a sensor that designates a Unix timestamp.
It would be much more practical to be able to refer to a sensor or a calendar event {{state_attr(‘calendar.XXXX’,‘start_time’}}
Thanks in advance!
