Can i use instead of the LAN module also the KM2 that has connection to vbus.net also?

Vbus LAN : https://www.resol.de/en/produktdetail/76
Vbus KM2 datalogger : https://www.resol.de/en/produktdetail/209

Nobody that has an answer?

The examples posted in this thread are for the LAN module

Dear all, hopefully somebody has a clue.

I have the resol module with script https://openrb.com/logicmachine-as-gatew...s-protocol
but keep getting the reply "* string: VBus modules not available"

Check that you have three user libraries created: user.luavbus, user.luavbuspacket and user.vbusprofiles

[KoBra]

Check that you have three user libraries created: user.luavbus, user.luavbuspacket and user.vbusprofiles

Yep they are all installed. incl the fixing of the bug on line 42 as described earlier in the topic.

Found this in the error log

Post a screenshot of your User libraries tab. Make sure that "auto load library" is disabled for all vbus libraries.

library names for vbus must be all lowercase

changed all the scripts to lowercase but no difference:

Do you have require('user.vbus') at the start of the scripts that needs to use the user libs?

Do you have require('user.vbus') at the start of the scripts that needs to use the user libs?

i changed line 9 in the script below from luavbus to vbus.

Code:

  name = "luavbus"
  local loader = searcher(name)
  if type(loader) == 'function' then

it seems it improved a bit because now the error logs show

This error means that the connection failed. Check that the IP address of Vbus device is correct and that you can ping it from LM.

It was online but not responsive, now we are back to the previous error. (i should have thought of this )

[admin]

Replace the top part of the user.vbus with this. Then restart the resident script via disable/enable. It will produce an error if your user libraries are not named in all lowercase (vbusprofiles and luavbuspacket).

Code:

local luavbus = {}

socket = require ("socket")
cjson = require("json")
vbusprofiles = require("user.vbusprofiles")
luavbuspacket = require("user.luavbuspacket")

local SERIAL, TCPIP = 0, 1

The response:

no file 'Library user.so'
stack traceback:

so i changed name from vbusprofile > vbusprofiles

Code:

no file 'Library user.so'
stack traceback:

User library vbus:16: in main chunk

so i changed vbuspacket to luavbuspacket

now the error is:

You need to remove these lines from the library:

    local loader = searcher(name)
    if type(loader) == 'function' then
      package.preload[name] = loader
      cjson  = require (name)
      break
    end
    name = "json"
    local loader = searcher(name)
    if type(loader) == 'function' then
      package.preload[name] = loader
      cjson  = require (name)
      break
    end
  end

  for _, searcher in ipairs(package.searchers or package.loaders) do
    name = "vbusprofiles"
    local loader = searcher(name)
    if type(loader) == 'function' then
      package.preload[name] = loader
      vbusprofiles  = require (name)
      break
    end
    name = "user.vbusprofiles"
    local loader = searcher(name)
    if type(loader) == 'function' then
      package.preload[name] = loader
      vbusprofiles  = require (name)
      break
    end
  end

  for _, searcher in ipairs(package.searchers or package.loaders) do
