Seed Studio offered me a sample device (see specs) for exchange for an article on my blog and I accepted. The device came a few weeks ago so I am fulfilling my part.
When it came, I went to their page and searched for some example code to test and I picked GitHub Stats example.

This project took me a year to finish but finally it’s done. What I wanted is to build an automatic IoT sprinkler controller from cheap parts. This is my story.

So I tried to compile exactly the same version and install it on the non working piece. I also put the same wifi config there but nothing. It didn’t work.
