TCP Socket Connection for Legrand

[a455115]

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()

Works perfectly!

Thank you very much for the help!
