What dietpi-controllable lights are people running?

DietPi has a few smart-home/IoT apps available, so this is aimed at people running any of those, with a primary focus on lighting control. What software-and-lights combos are people running on DietPI? In my ideal world, I can find something A), Low-power, ie USB/battery powered, and B) addressable with non-proprietary/open source software, over C) WLAN. Happy to hear about whatever folks are using in any other ways, but my use-case factors lightweight portability higher than embedded/“smart home” arrangements.

TL;DR: Looking for IP-controlled lights to use with DietPI.
