This Alexa skill helps you to schedule you time before you leave home. It's remember bus stop you use and gives you update every time you say "Alexa ask bus stop for update".
Completely hands and hassle-free :)
During setup process it will ask you for 5 digit bus stop number you can find on the plate at bus stop or via TFL website. To make Alexa understand number clearly try to read number grouped by few digits. For example instead of "12345" say "12-345" or "123-45"
