Unable to control my Keba P30 x-series

[Sceppi]

Writing this in English as I'm not a native German speaker.

My Keba P30 x-series has arrived, and I was anxious to use OpenWB to control the wallbox.
Unfortunately I'm unable to control the wallbox through open WB. Under Ladeparameter in openWB I can see how much is charged in Watt, so there is a communication. However, when I press "stop" or "Sofort Laden" or any other action, the wallbox does not respond. It's like there is a communication, but the wallbox does not let itself be regulated.

What I have done so far:
- The Keba is connected through LAN
- Dip switches are correctly configured as far as I can tell. i.e: 1.3 is ON (smart home interface), as well as 2.5 (Communication in the charging network is enabled)
- Upgraded my firmware to the latest version (1.12.1)
- I can reach and control the wallbox though the web interface
- Modulkonfiguration Ladepunkte: Keba, with IP address pointing to the Keba wallbox

I've read that port 502 should be open for Modbus communication. This does not seem to be the case. When I go to port.log in ramdisk I see the following error message: "sudo: no tty present and no askpass program specified"
There is also no keba_setcurr.log file in the Ramdisk.
The only files I can see related to Keba are keballlr2lp1, keballlr2xlp1, keballlr3lp1, keballlr3xlp1

I've read that the German version of the Keba does not work, however this is not the version that I have. I have the regular Keba P30 x-series (KeContact P30 x-series 105.155)

I'm out of ideas, any help is appreciated!

Hi,
Well the keba seems not to open port 502, atrached you see my dip switches setting and my installed softwareversion. I have one keba -x
Please check this against your installation, in case you still have problems, please show me all parameters. Which openWb version do you have ? Is it self installed ?
Otherwise while i read your total description it could be this:
The port.log should have some message like this:
01/23/2022, 18:00:46 check502.py ipadr 192.168.1.241 Port 502 is open
Based on the message below i would assume that your openWB setup is not complete:

I've read that port 502 should be open for Modbus communication. This does not seem to be the case. When I go to port.log in ramdisk I see the following error message: "sudo: no tty present and no askpass program specified

Hi Oliver,

Thanks for your quick reply. See screenshots below for my openwb and Keba configuration.
I'm running Openwb on a RPI 3B+. I re-installed my pi just before installing openWB and am running Raspbian Stretch on it. I followed the installation steps on github for the installation.

OK, seems I found the issue!

I reinstalled my RPI. Previously I had created a new user under which I had installed openwb.
This time, I installed openWB using the default pi user.
As far as I can tell, the wallbox is reacting now (but difficult to test since my battery is full )
In any case, the port.log is reporting an open 502 port and I see keba_setcurr.log in the ramdisk.

Even though I had given sudo rights to the new user in my initial install, it seems that this new user probably didn't have all the access rights as required. At least I think that's what the issue was.

Thanks for the support. Your reply "i would assume that your openWB setup is not complete" triggered me to reinstall, and that worked

Thanks for posting the solution,
