Home Assistant is an open source operating system for a localized Smart Home Hub. Basically it works like IFTTT or Samsung Smart Things, but without having to send your data out onto the internet. This means that you have total control over your data, limit the amount of internet traffic from your smart devices, and tighten up security. Along with all of those things Home Assistant also allows you to create complex Scripts and Automations that blow other such Smart Home systems out of the water.
This guide will walk you through setting up the Home Assistant server onto a Raspberry Pi using Hass.io. It then goes over some things to look for in devices that work best with this kind of system.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
