Bus 001 Device 015: ID 1781:0c31 Multiple Vendors 

To edit the /etc/tellstick.conf the simple tool is TelldusCenter, and was installed under /usr/bin/TelldusCenter.

I added a couple of test nexas to test with and got this /etc/tellstick.conf, also the

user = "nobody"
group = "plugdev"
deviceNode = "/dev/tellstick"
ignoreControllerConfirmation = "false"
device {
  id = 1
  name = "Rum3"
  controller = 0
  protocol = "arctech"
  model = "codeswitch:nexa"
  parameters {
    # devices = ""
    house = "D"
    unit = "3"
    code = "0000000000"
    system = "1"
    # units = ""
    fade = "false"
  }
}
device {
  id = 2
  name = "Rum2"
  controller = 0
  protocol = "arctech"
  model = "codeswitch:nexa"
  parameters {
    # devices = ""
    house = "D"
    unit = "2"
    code = "0000000000"
    system = "1"
    # units = ""
    fade = "false"
  }
