For thet majority of its existence, Home Assistant primary focus was on presence detection, lights and switches. But not anymore as we’re expanding the supported devices. Today, we’re proud to introduce Nest Thermostat integration for Home Assistant contributed by Stefano Fiorini!
The new integration exists out of two parts: a generic thermostat component and a Nest platform implementation. The initial version implements provides a read-only card and services to control it. The plan is in the future to add temperature and away mode controls from the thermostat card and more info dialog. Internally, we are using the Python package python-nest by jkoelker to talk to the Nest.
If you own a Nest thermostat, add the following lines to your
[thermostat] platform=nest username=YOUR_USERNAME password=YOUR_PASSWORD
Most people do not like configuring things. Things just have to work, out of the box. Reaching this scenario is the goal of what we are about to introduce: our new discovery component.
The discovery component will scan the WiFi network from time to time for connected zeroconf/mDNS and uPnP devices. The initial introduction is mainly focussed on getting the right architecture in place and discovers Belkin WeMo switches and Google Chromecasts connected to your network. When found, it will load and notify the appropritate component and it will be ready to use within seconds.
Most devices still require some sort of interaction from the user after being discovered - be it a button being pressed or some sort of authentication. This is a challenge that will be solved in the future.
To enable the discovery component, add the following to your
A new discovery section has been added to the Adding a new platform page with instructions how to make your platform discoverable.
One of the things that was missing in Home Assistant for a while was a way to communicate with users. Wouldn’t it be nice to get a message when important events happen like the lights being turned on while no one is home? Since the Home Assistant frontend runs as a web application on the phone, we have no way to bring ourselves to the front. This is where the new notify component comes in, powered by PushBullet.
The new notify component will take in messages and tells them to the user. For now this will be powered by the very awesome PushBullet but any other messaging platform can be easily added.
A message triggered by the simple_alarm component is shown by PushBullet on the Moto360.

The internet has been buzzing over the last year about home automation. A lot of different terms fly around like the internet of things, home automation and the smart home. This article will try to explain how they all relate.
The first thing to introduce is the Internet of Things (IoT). This refers to a new generation of devices that cannot only be controlled by humans via buttons or remotes but also provide an interface to communicate with other devices and applications. For example, an IoT-capable coffee machine could receive commands to create different types of coffee and be able to broadcast the amount of water left in its reservoir.
There is no widely adopted open standard for smart device communication. This prevents a lot of devices to communicate with one another. And even if they could, most devices are not designed to manage other devices. To solve this we need a device to be able to communicate with and manage all these connected devices. This device is called a hub.
As a bare minimum a hub has to keep track of the state of each device and should be able to control them if possible. For example, it has to know which lights are on or off and offer a way to control the lights. For a sensor it only has to know the value. A hub with these capabilities offers home control.Read on →
