I'd use "smart devices" as well, but specifically sticking with Z-Wave compatible ones.
That allows every device to communicate with every other, regardless of manufacturer. It also allows integration with such as keypad or pocket controllers, "smart hubs" with Z-Wave compatibility such as an MCV "Vera" & anything up to full home automation setups such as Homeseer.
And unlike a lot of other remote sockets etc., all Z-Wave devices are two-way and report their status back to the controller if switched locally, or the controller will show if any device does not respond to a command promptly.
A smart hub or Homeseer central controller will allow remote monitoring and control, plus you can set up "scene" combinations to be triggered manually or by the PIR sensors & with Homeseer you can add utility plugins such as an occupancy emulator, that switches certain lights on & off at random times.
eg. Look at the TBK Home TZ74 module. That can control two lights and work from two normal switches as well as Z-Wave.
There are many Z-Wave PIR sensors plus illumination, temperature and just about anything else you can think of.
