LM Lutron telnet listener

[imprashant]

Try this, no guarantees that it will work because we don't have any Lutron devices to test. Check Logs for any errors if the script does not work.
Adjust each query call as needed. First argument is the query request (without \r\n, it's added automatically), second argument is the status group address where the new value is written.

Code:

123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354

require('user.lutron') sock, err = lutron_login() if not sock then   log('no connection to device', err)   os.sleep(5) end function close(err)   sock:close()   sock = nil   log('receive failed', err) end function query(req, out)   if not sock then     return   end   sock:send(req .. '\r\n')   local res, err = sock:receive()   if not res then     return close(err)   end   if res:sub(1, 1) ~= '~' then     return close('invalid reply ' .. res)   end   if res:sub(2, #req) ~= req:sub(2) then     return close('invalid reply ' .. res)   end   local val = res:sub(#req + 2)   val = tonumber(val)   if val then     grp.checkupdate(out, val)   end end while sock do   query('?DEVICE,10,6,3', '1/1/1')   query('?DEVICE,10,1,2', '1/1/2')   query('?DEVICE,10,3,4', '1/1/3')   if sock then     os.sleep(5) -- delay between each poll cycle   else     break   end end

The script you have shared worked, but sometimes it goes into the sleep mode or update the status very late. Also How do I get the brightness status through this script. I am using the event based script to send the brightness value command to lutron. Please guide

require('user.lutron')
tcp, err = lutron_login()
if not tcp then
  log('no connection to device', err)
end
value = event.getvalue()
value = math.floor(value)
 
tcpend('#OUTPUT,151,1,'..value..'\r\n')
