Just another update
Everything is working now. The problem was that after reflashing the default GPIO settings for the I2C on which the display is attached were not correct. It probably tied to communicate with the display on the wrong GPIO and it hanged. So after selecting the correct GPIO for I2C respectively GPIO2 and GPIO14 everything works fine. Now I try to find out how I could controle it from my mobile phone over mqtt.
