Somfy RS-485 Protocol

[Ravi Kiran S]

Hi

i have created this in user.somfey in liberary


Somfy = {
ch01 = {
 up = string.char(0x7F,0xF2,0xFA,0xB8,0x43,0xFA,0x00,0x00,0x00,0xFF,0xFE,0x06,0x5D),}}


and in event communication function also i have done this code also

- Send to Somfy transmitter
somfy_send(cmd)
port = require('serial').open('/dev/RS485', {
baudrate = 4800,
parity = 'odd',
duplex = 'half',
databits = 8,
stopbits = 1
})
port:write(cmd)
end

but the last end i given the error so i have removed end also

In event base script i have done the
omfy_send(cmd)
port = require('serial').open('/dev/RS485', {
baudrate = 4800,
parity = 'odd',
duplex = 'half',
databits = 8,
stopbits = 1
})
string.char(0x7F,0xF2,0xFA,0xB8,0x43,0xFA,0x00,0x00,0x00,0xFF,0xFE,0x06,0x5D),}}
this with the hexacode given by somfy vendor

but the contoller is not working


so please tell the procedure todo because i am doing it first time


Thanks
