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

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

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?

endit seems it improved a bit because now the error logs show Code: 12345 User library Vbus:716: bad argument #1 to 'pairs' (table expected, got nil)

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.

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: 12345678 local luavbus = {}
socket = require ("socket")
cjson = require("json")
vbusprofiles = require("user.vbusprofiles")
luavbuspacket = require("user.luavbuspacket")
