OBI Wifi Socket - seurat-atreides/Sonoff-Tasmota GitHub Wiki

Where to buy

As shown in the name the Wifi Socket is only available in the OBI Diy-Warehouse. It can also be bought in the OBI online-store

Open the socket

Opening the socket is kind of difficult. If you have one of the Tri-Wing screwdrivers it is much more easier. If you haven't got use a normal head screwdriver. Be careful not damaging your hand with it.

Tipp: Afterwards use normal cross screws to close the casing.

Connection

ESP	Programmer
VCC	3V3
TX	RX
RX	TX
GND	GND

Connect GPIO0 to GND before connecting power to enable flash mode!

Additional Information

A low pulse on GPIO12 switches the relay on, a low pulse on GPIO5 switches it off.
I have solved the 'pulse issue' by setting GPIO12 to always 0 (as LED) and works fine.
More Infos can be found here: #1988.

Initial Configuration

In the default configuration GPIO0 (which is also used to enable flash-mode) is setup as a Button.
To enable AP-Mode and setup the correct GPIOs as described below,
You can short GPIO0 to GND 4 times as if it was a button (see Button-usage)
Using this method allows you to flash a precompiled binary
