This is a case for the internals of the HUBSPACE “Indoor Outdoor Smart Screw-Based Lighting Socket”. Possibly because of the terrible name or it's inability to fit in the majority of outdoor lighting sockets HomeDepot was clearing these out at a steep discount. This units include a ESP32 and a 10amp relay. This case enables you to install them inline with an appliance you want to control. It includes an access hole so you can still use the reset / toggle button when needed.
