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

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

Code:

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

log_level = WARN
if ( vbus == nil ) then
  log ( "VBus modules not available")

end
vbus.new(nil, TCPIP, "vbus" )

vbus.remote_host = "192.168.0.188"
vbus.remote_port = "7053"
vbus.password = "vbus"

vbus:connect()

-- filter = { srcAddress = 0x7e11, dstAddress = 0x0010 }
-- filter = { command = 0x200 }

packets = vbus:waitData(filter, 30 )

if (packets ~= nil ) then
  log( string.format ( "Returned %d packets", #packets ) )
  for key, packet in pairs(packets) do
    -- print ( string.format ( "Packet: %s", packet ) )
    -- print ( packet:profileprint() )
    if ( packet.profileData ~= nil) then
      for k, data in pairs ( packet.profileData ) do
        if ( data.factor < 1 ) then
          log( string.format ( "Name %s Value %.02f %s", data.name, data.value, data.unit ) )
        else
          log( string.format ( "Name %s Value %d %s", data.name, data.value, data.unit ) )                 
        end
      end

    end
  end
else
  log( "No packet!!!")
end

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

Code:

User library Vbus:716: bad argument #1 to 'pairs' (table expected, got nil)
stack traceback:
[C]: in function 'pairs'
User library Vbus:716: in function 'readDevicesProfiles'
User library Vbus:233: in function 'waitData'

(09.01.2023, 08:41)admin Wrote: 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
