Particle-controlled relay board (https://docs.particle.io/datasheets/kits-and-accessories/particle-shields/#relay-shield) hooked up to four power plugs, controlled by events on several MQTT topics.
The four power logs can be hooked up to arbitary stuff, such as various lamps.
Compilation and deployment (flashing the mcu) is handled by travis-ci.
Installation (and updates) of the particle CLI tools is done using make setup. Compilation is done by running make build. You need to login to particle cloud first (make login).
