No data on dashboard

[Robert]

Hi, new user here. I finished building de AirGradient DIY yesterday It is showing the different readings happily.

I added the device to the dashboard using the free account option. After 24h there is still no data in the dashboard. I used the 6 characters from the init screen (lower case) to register the device.

Any ideas what I should do to start seeing data?

I (also) do not know how I should debug the communication. If I try to use the Arduino serial port monitor I see some gibberish.
I was expecting that the log messages would appear in the console part of the Arduino tool itself, but that does not happen. (My settings: Lolin(wemos) D1 mini pro, Debug port = Serial; Debug level: the longest option SSL+…+ CORE+ …)

Thanks!

Edit: The serial port monitor shows gibberish like this:
15:35:55.116 → ⸮⸮⸮f~⸮⸮fx⸮⸮⸮xf⸮⸮⸮⸮⸮⸮⸮⸮⸮f⸮⸮⸮⸮⸮fx⸮⸮

Ok, I re-flashed the Wemos D1 and then the serial monitor started working. In the log I saw that the connection to airgradients dashboard gave http-400 errors. I re-registered the device and now I see data appearing in the dashboard.
Problem solved.
