Well... i decided to buy another i2c device and test it. the result: this works without any problems, so i think my board is faulty..

I use the unipi 1.
You mean i have to install a library like json, to get access to the inputs and make use of them in a python program?
Then i do not understand why there is a table in the users manual, where you show which gpio on the raspi belongs to the different inputs of the unipi?

Hi guys,

i´m really new to this and have a problem..
I´ve read all the things on github, but i just won´t get a clear mind.
I just want to read Input 1 of the board. Why can´t i just write a python programm where i read the GPIO 04 (Pin 07 on the Raspi) to read Input 1?
What else do i have to do? I really don´t get it.. Are there some examples for reading Inputs in Pyhton?
Please help me and thanks a lot for your time.

Greetings s0fralk

No more idea? Is there a possibility to check the relays/board itself? Normally it should work after installing evok as shown on github, right?

That was my first thought too, after reading this log. So I enabled it manually just to go safe, but it didn´t changed anything. Here is a list of the i2c module:

pi@raspberrypi:~ $ lsmod | grep i2c_
i2c_bcm2708             4834  0 
i2c_dev                 5859  6 

pi@raspberrypi:~ $ sudo i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

Hey Community,

i just will not get started with your UniPi v1.1..
i have installed the evok software as shown on github
(https://github.com/UniPiTechnology/evok). If i now type in the ip of my raspi, into my
browser, i only see the inputs of the board. If i click the outputs,
i just see the header "Outputs", but not one relay is listed here (Screenshot).
On the internet i don´t really get some information, what the problem could
be. Do you have any idea how it could work?
Is there a possibility, to check if the board is working correctly?

I am using a Raspberry Pi3B with the OS: 2017-03-02-raspbian-jessie
The UniPi´s rev is 1.1

Further i have some screenshots for you and a logfile
