@juntiedt After you changed the port in /etc/evok.conf to 8080, did you restart it? I think it should not work, because there is the some webserver running on 8080. Check it with

netstat -putan

is it possible that I have a problem with tornadorpc-evok. I am not sure if it is installed the correct way. please let me know how to install it and where I can find the correct installation file.

regarding your question: no web server running

@juntiedt Some server is running because it responds with 404... The tornado-rpc evok is part of evok itself. Please try to reinstall evok and paste the output of the installation script

juntiedt

ok, I will reinstall evok.
Wich one would you recommend?
Legacy or Evok 2.0 on my unipi1.1 with stretch

tomas_hora

@juntiedt 2.0

juntiedt

new stretch image, new evok --> all works perfectly!
thanks Tomas

Hi Tomas,
I was too optimistic yesterday. Today I tryed your websocket based sample programm with Python 3. Python can't find websocket. Do I have to install a websocket library? If yes which one?

There is another problem I found when rebooting after installing evok.
During booting raspbian stretch I got this warning message:
"Failed to start load kernel modules"
Could this be the reason why websocket does not work?

I am running plain stretch with latest update and upgrade

sorry for the websocket issue. Its now running.

the only thing left is the unipi_eprom problem in the boot process of Raspbian
