@stickyrib with the 2.4 release a heating problem arose with heavy cpu usage due to electron. Is was adviced tot use the fkms (see post michael). When i followed up on this post both alternatives did not work out for me. One option got me star night like flickering in the widgets on screen, the other led to what you described. So I returned to the driver which was used up unto 2.3.
Never thought about powering via the monitor to be the probleproblem/solution, but I do connect it that way.

So still on default screen driver and no heating problem and no flickering.

@Peter Did a small addition with time labels under the graph. checked it in on github.

@electros you could look at mmm-bustimes. It is a similar module and also parses a json file (a different one) into a table
Git link. https://github.com/73cirdan/MMM-bustimes

Its not that hard electros. Mykle isn’t the youngest either:grinning_face_with_smiling_eyes:

Make 1 small target at a time. Eg

1 run an existing module eg bustimes
2 change the nodehelper to read your datasource
3 decide on the dataformat to feed into the getdom
4 format the dataformat
