Is it possible to create new integration for Home Assistant ? :
Slovakia - Bratislava (Capital City) - Bus Schedule
Bratislava has open data on page
API Open Data Bratislava
This is the page where it is implemented
I suggest you to use/display (with an iframe/webpage card) the below in your homeassistant, it does not provide any sensor which you could use in some automations, but it displays “actual” data with the current delays, if any.
You just have to search for your stop on imhd.sk , and then grab the link to the iframe from the source code, the only thing that changes is the “st” at the end which represents a different stop.
Dúfam že pomôže
