Greetings, @baleanex - and welcome to the forums!
Sorry to hear you’re having trouble with this project. While I haven’t built / deployed this project, specifically - I’ll do the best to help.
I’ll start with some basic questions (apologies if the answers are obvious):
Are you attempting to deploy using the “Deploy with Balena” button in the middle of the referenced blog post?
When you were trying the WiFi configuration – I assume you were entering your WiFi details (SSID and password) in the appropriate section under “Advanced Settings”?
It appears that this project requires a series of environment variables to be set (departure station, refresh time, etc) – but I wouldn’t expect any of these items to prevent the device from showing up in Balena Dashboard.
I’m a relative N00b myself, so again, just enumerating somet of the more basic things. Can you share what you see / experience after deploying?
There was a time when I considered building this project, to see if I could adapt it to BART here in the San Francisco bay area but since early 2020, my mass transit ridership has been way, way down.
We’ll get it figured out - even if we have to pull in some of the big guns who will have far better questions to ask, logs to check, etc.
