S1-Series---Wifi-Socket-S120-(EU-model)-chipset-TYWE2S.md

Model

There's no brand on this one, I got it for 11€ on ebay as "Wifi Smart Sans Fil Télécommande Prise de Courant Pour Téléphone Prise EU Plug" from this seller.

Flashing

As chipset is a TYWE2S, you'll have to connect GPIO0 (marked IO0) manually to the ground.

There's better images than mines here and here on the wiki.

Configuration

• GPIO5: Relay1 (21)
• GPIO12: Led1 (52)
• GPIO14: Button1 (17)
