Re: LCD 1602 HD44780 SPI
I have not tried the 64*128, maybe they are different. The 12864 LCD doesn't work with ESPEasy, it works over the SPI bus and I used the U8Glib with Arduino to let it work. http://www.aliexpress.com/item/128-64-DOTS-LCD-module-5V-blue-screen-12864-LCD-with-backlight-ST7920-Parallel-port-LCD12864/32...

I solved my problem
Under Optional Settings I gave the field : 'Value Name 1' the name Vcc
For the Oled I used this line: Vcc [Vcc#Vcc} and it magically worked.

I tried:

Re: reed relais
Don't forget that a level converter only transforms the voltage level. All the current that flows through the relais will flow out or into the GPIO of the ESP. Max current a GPIO can safely handle is 12mA note#. So if your 5V relais has a coil-resistance of 500 ohm the current will be 5/500=0,01A or...

Re: ESP12F - switching a Relay off turns the wireless LED onboard BRIGHT BLUE ?
It is just by design.
Some ESP modules have the blue Led connected to GPIO2.
So the led will turn on when GPIO2 is made 'LOW' which explains what you see.
