@ianperrin for some reason the calendar is not showing up.
I did all the steps from the github page including the localhost:8080 link and a update but is not working.
Is it for you still working?
EDIT:
The command log shows:
Create new calendar fetcher for url: http://localhost:8080/MMM-Formula1/schedule.ics - interval: 3000000
Calendar Error, could not fetch calendar: url: http://localhost:8080/MMM-Formula1/schedule.ics…
error: invalid url: “http://localhost:8080/MMM-Formula1/schedule.ics”
