Hello together,
i have tried everythin what i can do, and for me it is not possible to connect to my Jura E8 (EB)
Normaly it is very easy installation when i see the pictures. I use an Wemos D1 mini and use external power. I have only soldered 3 wires, GND, D1 and D2. and use this esphome yaml.
Can anyone help me.
