Hi

Is there a script that can get status out of a Helvar routersystem with HelvarNet?

Try this script to check communication to HelvarNet. It will send query command every 3 seconds. If this works then status map to group address can be implemented.
Resident script, sleep time = 0. Change 192.168.1.1 to HelvarNet router IP. Change 1.1.2.15 to the address of the device you want to query. You will get raw and parsed replies in Logs tab.

Code:

if not sock then
  ip = '192.168.1.1'

  sock = require('socket').udp()
  sock:setsockname('*', 60001)
  sock:settimeout(1)

  ptime = os.time()

  function parseitem(res, item)
    if item:sub(1, 1) == '@' then
      if item:find('=') then
        local addr, val = unpack(item:split('='))
        res.addr = addr:sub(2)
        res.val = val
      end
    elseif item:find(':') then
      local key, val = unpack(item:split(':'))
      res[ key ] = val
    end
  end

  function parse(data)
    local res = {}

    if not data:find('#') then
      return
    end

    res.type = data:sub(1, 1)
    data = data:sub(2, -2)

    local items = data:split(',')

    for _, item in ipairs(items) do
      parseitem(res, item)
    end

    log(res)
  end
end

data = sock:receive()
if data then
  log(data)
  parse(data)
end

ctime = os.time()
if (ctime - ptime) >= 3 then
  ptime = ctime
  sock:sendto('>V:1,C:152,@1.1.2.15#', ip, 50001)
end

First thanks for help. 
Tried changed the IP and device address as followed but doesnt get any in log or error log. ? 
I checked the push message in Helvar designer is set to True.

Code:

if not sock then
  ip = '192.168.1.14'

  sock = require('socket').udp()
  sock:setsockname('*', 60001)
  sock:settimeout(1)

  ptime = os.time()

  function parseitem(res, item)
    if item:sub(1, 1) == '@' then
      if item:find('=') then
        local addr, val = unpack(item:split('='))
        res.addr = addr:sub(2)
        res.val = val
      end
    elseif item:find(':') then
      local key, val = unpack(item:split(':'))
      res[ key ] = val
    end
  end

  function parse(data)
    local res = {}

    if not data:find('#') then
      return
    end

    res.type = data:sub(1, 1)
    data = data:sub(2, -2)

    local items = data:split(',')

    for _, item in ipairs(items) do
      parseitem(res, item)
    end

    log(res)
  end
end

data = sock:receive()
if data then
  log(data)
  parse(data)
end

ctime = os.time()
if (ctime - ptime) >= 3 then
  ptime = ctime
  sock:sendto('>V:1,C:152,@1.14.1.61#', ip, 50001)
end

Try changing local port from 60001 to 50001. If it still does not work then the example should be modified to use TCP instead of UDP.

Great! changed the port 50001, and now I get information in log.

Hi!

This story with Helvar, did you got some results or working solution?
Interested to use LM instead of Helvar BACNET gateway.
