Connected home is an idea of creating a\nhome where virtually everything is connected\nto the internet, from doors to lighting system, appliances (television,\nrefrigerator, washing machine, etc.) and\neverything you can imagine of is connected and controlled remotely.<\/p>\n\n\n\n

Before we delve into the use case, let\u2019s\nunderstand the current landscape of a connected home and challenges that needs\nto be addressed. The real challenge in a\nconnected home is using a standardized protocol for communication. Current\nvendors are taking a step in this direction, for instance providing a hub\n(think this as a device gateway) and a set of compatible devices which can\ncommunicate to the central hub. The devices include sensors to detect movements\n(when people arrive and leave home), vibrations, temperature, switches (to\ncontrol small appliances like a thermostat) and lighting systems (like bulbs,\nled, etc.).  The protocol used for\ncommunication is usually non-standardized, proprietary and low-frequency radio\nprotocol like ZigBee or Z-wave which is\ntypically used by lighting system (bulbs, led, etc.)<\/p>\n\n\n\n

When we mean non-standardized, we mean that\nit is not possible to bring a connected TV from a different manufacturer, or a\nconnected washing machine from a different vendor and make it talk to your\nconnected home ( or hub we talked about). \nYou don\u2019t want to have multiple hubs and manage each one of them\nindependently and some devices might not need a hub and can talk to the cloud\nplatform directly via WI-FI. Everyone is providing a hub model and set of APIs\n(open source, proprietary) and prompting device manufacturers to build around\nthe APIs for connectivity.<\/p>\n\n\n\n

The real use cases are not about providing\nseamless connectivity, but once connected, what value you want to derive from a\nconnected home. It\u2019s not only about home automation, but how would you use the\nvast amount of data generated to come up with new business models and innovative\nsolutions.<\/p>\n\n\n\n

Let\u2019s talk about one such case, where you\nwould like to optimize the electricity usage across your home, predict\nelectricity usage for the current month based on actual usage and optimize it\nfor the remaining days in a month and identify patterns and recommendations\nfrom the system.  Unless you gather data\nacross these connected devices to understand the usage and electric consumption\nfrom the devices, it would be difficult to come up with services such as <\/p>\n\n\n\n
