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.

Got it, I always thought that busses and trams would stop every couple of minutes. A ten minute wait is indeed a bit too much at those temperatures.

Living in warm country I don't really understand why people would live in such harsh conditions but that is a different topic :)

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.

I don't really understand, don't you just go out of your house, go to a bus-stop and wait for the next one? Isn't the bus arrival display more of a convenience to know how long to wait? For the bus stop in my neighborhood I see busses every couple of minutes.

You're very lucky to have high frequency transit. I've lived in several places (in cities) where the bus routes ran every 20-30 minutes. So if you don't feel like waiting at a bus stop for 20 minutes, often these days one without any seats, it's nice to be able to check the ETA.

Got it. I typically use my legs or bicycle to get from A to B. Don't like being stuffed in a metal box with strangers. 20-30 minutes would definitely warrant a nice display on your fridge!
