To install udev rules, you also have to add `services.udev.packages = [ pkgs.rwedid ]` into your configuration.
Additionally you will also have to create the i2c group, on NixOS this can be done using `users.groups.i2c = {};`.
And you will have to load i2c-dev kernel module, for that add `boot.initrd.availableKernelModules = [ i2c-dev ] to your config.
