TCP Socket Connection for Legrand
#29
You need a separate socket connection for commands. You also need to send another init sequence: *99*0##.
This example should control light point 11 by converting 0..100% value to 0..10. There's some extra logging to check if the message flow is correct. Remove it when the script is working properly.
Code:
value = event.getvalue()
value = math.ceil(value / 10)

cmd = '*1*' .. value .. '*11##'

sock = require('socket').tcp()
sock:settimeout(1)

res, err = sock:connect('192.168.1.247', 20000)

if res then
  sock:send('*99*0##')
  
  res, err = sock:receive(6) -- receive ACK
  log('receive 1', res, err)

  res, err = sock:send(cmd)
  log('send', res, err)

  res, err = sock:receive(6) -- receive result ACK/NACK
  log('receive 2', res, err)
else
  log('connect failed', err)
end

sock:close()
