The house is figuratively glued together using PubNub, allowing us to publish messages into the house to request on-demand readings from the sensors. Additionally, PubNub powers the remote configuration for the smart home, enabling users to trigger the LEDs and control the front door. We can also request the current state of the house, including voltage and intensity levels.
But the most valuable part of the Raspberry Pi-Controlled smart home is its showcase of the missing link in a lot of IoT applications and projects; powering an easy way to stream data in and out of an embedded device.
