HDL Buspro gateway integration with LM5

[admin]

Try this:

Code:

if not sock then
  require('user.hdl')

  sock = socket.udp()
  sock:settimeout(60)
  sock:setsockname('*', 6000)

  HDL.init()
end

data = sock:receive()
if data then
  packet, err = HDL.decode(data)

  if packet then
    if packet.opcode == HDL.cmd.chanregreply then
      channel, _, value = packet.additional:byte(1, 3)
      
      if channel == 1 then
        grp.checkupdate('1/1/1', value)
      elseif chanel == 2 then
        grp.checkupdate('1/1/2', value)
      elseif chanel == 3 then
        grp.checkupdate('1/1/3', value)
      elseif chanel == 4 then
        grp.checkupdate('1/1/4', value)
      end        
    end

    -- packet.additional = lmcore.strtohex(packet.additional)
    -- log('HDL packet', packet)
  else
    log('HDL error', err)
  end
end

If you have multiple HDL relay devices then you need to check packet.srcdevice value to determine the status group address.
