Connecting over the network (ser2net)

It's not always practical to communicate with the meter via (USB-to-)serial. Using ser2net on a (small) device close to the meter you can expose it on your network.

Example configuration:

connection: &mykamstrup
  accepter: tcp,2002
  connector: >-
    serialdev,
    /dev/serial/by-id/usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_0001-if00-port0,
    1200n82
  options:
    max-connections: 1

This above example uses TCP port 2002 on the host. A connection can be made from any other host using the socket:// URL handler with PySerial like this:

$ pykmp-tool --serial-device socket://hostname:2002 [...]

Or use the environment variable to not having to specify it in every command:

$ export PYKMP_SERIAL_DEVICE=socket://hostname:2002
