Hi!
I have a project with Lutron integration and I follwed the thread below to setup LM.
https://forum.logicmachine.net/showthrea...ght=lutron
While LM successfully works as listener and I can see everry log from Lutron device and button,
any Lutron command that I send does not seem to be reaching and nothing will be shown in the log.
My event script is pretty simple as below. (I have lutron user script and resident script as shown in the forum thread above)
Code: require('user.lutron')
tcp, err = lutron_login()
if not tcp then
log('no connection to device', err)
end
tcp:send('#DEVICE,5001,1,3\r\n')
Other things that I tried;
・I used ping command of LM network utility and checked if LM can reach Lutron interface and it was successfull.
・I confirmed lutron_login function returns response "QNET>" which proves login to the Lutron interface is successful.
・I installed telnet command on my PC (which is located in the same network as LM) and tried executing Lutron commands and it was successful.
Could you think of any reason that I cannnot execute command from LM event script?

Modify lutron_login() in the user library to log the data that is sent to LM.
Code: function lutron_login()
local tcp, tcp_err = lutron_connect()
if not tcp then
return nil, tcp_err
end
local res, err
res, err = tcp:receive(7)
log(res, err)
tcp:send(user..'\r\n')
res, err = tcp:receive(10)
log(res, err)
tcp:send(password..'\r\n')
res, err = tcp:receive(9)
log(res, err)
if res == nil or res == 'bad login' then
tcp:close()
return nil, res
end
return tcp
end
Add log(lutron_receive(tcp)) at the end of your script to check the reply.

Dear admin,
Appreciate your advice so much,
I am not sure what happened but when I added "lutron_receive(tcp)" at the end of the script everyting started to work!
Thank you so much for your advice as always!

Hi everyone,
I need to send commands e receive responses from a RA2 Select Lutron gateway.
I currently use the Lutron library to log responses and errors of the TCP communication, but can not log in.
This below is the output log from a event-based script.
Code: Event for prova lutron cmd (1/1/1) 16.09.2024 13:36:20
* arg: 1
* string: login:
* arg: 2
* nil
Event for prova lutron cmd (1/1/1) 16.09.2024 13:36:20
* arg: 1
* string: password:
* arg: 2
* nil
Event for prova lutron cmd (1/1/1) 16.09.2024 13:36:50
* arg: 1
* nil
* arg: 2
* string: timeout
Event for prova lutron cmd (1/1/1) 16.09.2024 13:36:50
* arg: 1
* string: no connection to device
* arg: 2
* nil
I copied and pasted the library without changing anything but IP and credentials. I am sure IP and credentials are correct because I tried copying and pasting them into Putty telnet service and I have no problem sending commands to the lutron device

Try this modified function and post what you get in Logs:
Code: function lutron_login()
local tcp, tcp_err = lutron_connect()
if not tcp then
return nil, tcp_err
end
local res, err
res, err, partial = tcp:receive()
log(res, err, partial)
tcp:send(user..'\r\n')
res, err, partial = tcp:receive()
log(res, err, partial)
tcp:send(password..'\r\n')
res, err, partial = tcp:receive()
log(res, err, partial)
if res == nil or res == 'bad login' then
tcp:close()
return nil, res
end
return tcp
end

So here is the log:

* string: timeout

* string: password:
Event for prova lutron cmd (1/1/1) 16.09.2024 14:21:35
* arg: 1
* nil
* arg: 2
* string: timeout
* arg: 3
* string: GNET>

Replace all 3 log() calls with loghex() and try/post again.

I now get what the problem was in the last function after the password was sent I waited for tcp:receive(9) but it only responded with 5 (GNET>)characters so it always gave back the timeout error and with res being nil the function always returned nil.
Thanks admin you made me realise what the problem was
Now new problem, is there a way I can avoid logging in every time I send a command?
