These dont require WIFI or the hub but do require 3 batteries to power. They are pretty simple and may be used to auto turn on a soft yellow night light so you can wonder around the house at night. THere is another version with in an inbuilt battery which requires charging every 3 months for a few dollars less. Personally i prefer to the batteries required version (this one) as it provides a good home for your eneloops, and these dont require removal of the device to charge.
I dont now whether these are water proof.
