Log all bus traffic

[admin]

Something like this, though it will not work on older FW where grp.all function is not implemented.

Code:

if not client then
  require('genohm-scada.eibdgm')

  objects = grp.all()
  datatypes = {}

  for _, object in ipairs(objects) do
    datatypes[ object.id ] = object.datatype
  end

  function writehandler(event)
    local dpt = datatypes[ event.dstraw ]
    if dpt then
      local value = knxdatatype.decode(event.datahex, dpt)
    end
  end

  function readhandler(event)
    log(event)
  end

  client:sethandler('groupwrite', writehandler)
  client:sethandler('groupresponse', writehandler)
  client:sethandler('groupread', readhandler)
end

-- handle knx
client:step()
