      Hi Tomas,

      when I use localhost:8080 I receive the very long error message above. However, when I use localhost:80 and your request I receive the error message below. Does this tell you something?

      regards
      Hannes

      import http.client
      
      payload = "{\"value\":\"1\"}" 
      headers = {'content-type':"application/json"}
      
      conn = http.client.HTTPConnection("localhost:80")
      conn.request("POST", "/json/relay/5", payload, headers)
      response = conn.getresponse()
      print(response.status, response.reason)
      data = response.read()
      print(data)
      conn.close()
      

      I get this respones:

      404 Not Found
      b'<html><title>404: Not Found</title><body>404: Not Found</body></html>'

        @juntiedt Are you sure that evok is running on localhost on port 8080?

          evoc is running. I checked it with "systemctl status evok"
          I checked "/etc/evoc.conf. port" which was set to 80. Actually I haven't changed anything since installation! Changed it now to 8080.
          I am getting the same response as before: 404 Not Found ... see above - but now on port 8080

          Is there another file where I should/could change the port to 8080?

          does body mean payload and title mean headers?

              @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

                          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
