More commute poking.
Firstly, I set up monitoring for the two LUAS stops I use, using The API. There is also data on lag which I have not used. I will wait to see how useful it is.
Secondly, I set up polling every 10 minutes for how fast Google thinks a commute will take, including if traffic is slow (yellow in Google maps) or stopped (red). Will see what emerges. Cost so far is 8 USD a day.
