Ok, I go second then :)
My name is Fernando and I live in Spain. I have taken some time off but I use to write on several Spanish blogs. You can find an article about M5Stack here in Xataka Home. I'm currently using UiFlow and I'm starting to like it a lot, although I am used to program ESP8266 and ESP32 devices using Arduino and C is my favourite language.
Now I'm working to integrate Blynk with it for revisiting a project of mine and see if I can make it work better.
