[SOLVED] The serial port does not appear in the drop-down list. Topic is solved

[JeanBonnot]

Hi all,

The serial port, which is functional from the system, does not appear in the list of usable serial ports ( other ports appear ).
By manually entering the serial port name ( /dev/ttyS1 ) in the database ( for Teleinfo hardware ), it works perfectly.

Why doesn't this port appear? And what can I do to get it listed?

Thanx

I believe Domoticz only list ttyUSB, ttyACM or serial/by-id devices. Did you create that serial port name yourself?

@waltervl : Thx for reply and yes, i have 'created' this port manually

Okey.... How did you connect the serial port? Directly on the raspberry pi pins?
In this case, it's indeed not detected as a USB device
You can make a hard link to /dev/ttyUSBS1 yourself

Otherwise, get yourself a USB->232 TTL cable?

@gizmocuz thx for helping, but ..
the serial port works perfectly, the only small problem is that it is not listed in the list of usable serial ports.

I fixed the problem by adding a symlink in /dev/serial/by-id :

Code: Select all

~sudo ln -s /dev/ttyS1 /dev/serial/by-id/ttyS1_GPIO

Now the serial port appears as ttyS1_GPIO
