RE: communication vbus solar resol - KoBra - 09.03.2021

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?

RE: communication vbus solar resol - admin - 16.03.2021

The examples posted in this thread are for the LAN module

RE: communication vbus solar resol - KoBra - 02.01.2023

Dear all, hopefully somebody has a clue.

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

RE: communication vbus solar resol - admin - 03.01.2023

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.

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

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:

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

After starting the resident script now i get a different error.

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 Angel

)

RE: communication vbus solar resol - admin - 09.01.2023

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

so i changed name from vbusprofile > vbusprofiles

stack traceback:

so i changed vbuspacket to luavbuspacket

now the error is:

You need to remove these lines from the library:

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