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.
