RS485

[buuuudzik]

Try a connecting to a different port,  I found that with a LM4 only one port was working

I created a function and stored this in the Common scripts.

Code:

function sendSOMFY(command)
 require('serial')
 port = serial.open('/dev/RS485-3', { baudrate = 4800, parity = 'odd', duplex = 'half', databits = 8, stopbits = 1 })
 port:flush()
 port:write(command)
 port:close()
 sleep(0.1)
end

Also the codes you use,  there are different versions of the Somfy command generator.  Depending on what type of motor being used each version may generate a different RS485 command.  Also be sure your selecting the right addressing scheme, ie individual or group which is determine by how that motor has been programmed.

Did you prepare also the reading data from the Somfy or only sending? I am before such integration. Can I check if blind received the data?
