I built a hardware display, with an LCD and a WeMos Mini D1, so that I can see the upcoming tram departure times outside my house. I could use the website, or a phone app, but having the departure times always present right by my front door is a real game-changer.

The actual tram-stop does indeed have a display, but here in Finland it might be -20°C in the winter time so I don't want to walk to the stop earlier than necessary.

Sure waiting ten minutes won't kill me, but I'd much rather wait 1-2 minutes instead. Keep myself toasty-warm indoors.

Not all of them do. It's also nice to have one closer to you, so you don't have to walk to the bus stop to find out when it's time to leave house for the bus...

You could check on the phone, but I could certainly see the appeal of a fixed display in a convenient location.
