Not sure if it´s official one… Came from China… 
so… will try something else… meantime… connected PC there…
If there is the logo of Arduino and says: Made in Italy, so it is original. The logo should be on both sides of the board. Otherwise it is Arduino Compatible device
It should work fine, but I only ask because knockoffs can have some questionable parts. I would try another device to see if it makes a difference.
I am getting disconnected every day and I have to reboot. Sometimes it solves the problem and gets online but, for example right now, it’s disconnected and I can’t control the blinds. They are closed and I need to open them. After a while (minutes, hours) it goes online.
Any ideas ?
Thanks
