<p>I recently learned about the ESP8266, a $5 chip that includes WiFi and is Arduino compatible. This means
|
||||
that all your DIY projects can now be done for a fraction of the price.</p>
|
||||
|
||||
<p>For this tutorial, I’ll walk through how to get going with ESP8266, get the temperature and humidity and
|
||||
report it to MQTT where Home Asssistant can pick it up.</p>
|
||||

||||

|
||||
Home Assistant will keep track of historical values and allow you to integrate it into automation.

<h3>Components</h3>
|
||||
|
||||
<p>I’ve been using Adafruit for my shopping:</p>
|
||||
|
||||
<ul>
|
||||
<li><a href="http://www.adafruit.com/product/2471">Adafruit HUZZAH ESP8266 Breakout</a> (<a href="https://learn.adafruit.com/adafruit-huzzah-esp8266-breakout/assembly">assembly instructions</a>)</li>
|
||||
<li><a href="http://www.adafruit.com/product/2635">Adafruit HDC1008 Temperature & Humidity Sensor Breakout Board</a> (<a href="https://learn.adafruit.com/adafruit-hdc1008-temperature-and-humidity-sensor-breakout/assembly">assembly instructions</a>)</li>
|
||||
<li><a href="/components/mqtt.html#picking-a-broker">MQTT server</a></li>
|
||||
</ul>
|
||||
|
||||
|
||||
<p><em>Besides this, you will need the usual hardware prototype equipment: a breadboard, some wires,
|
||||
soldering iron + wire, Serial USB cable.</em></p>
|
||||
|
||||
<h3>Connections</h3>
|
||||
|
||||
<p>On your breadboard, make the following connections from your ESP8266 to the HDC1008:</p>
|
||||
|
||||
<table>
|
||||
<thead>
|
||||
<tr>
|
||||
<th> ESP8266 </th>
|
||||
<th> HDC1008 </th>
|
||||
</tr>
|
||||
</thead>
|
||||
<tbody>
|
||||
<tr>
|
||||
<td> GND </td>
|
||||
<td> GND</td>
|
||||
</tr>
|
||||
<tr>
|
||||
<td> 3V </td>
|
||||
<td> Vin</td>
|
||||
</tr>
|
||||
<tr>
|
||||
<td> 14 </td>
|
||||
<td> SCL</td>
|
||||
</tr>
|
||||
<tr>
|
||||
<td> #2 </td>
|
||||
<td> SDA</td>
|
||||
</tr>
|
||||
</tbody>
|
||||
</table>
|
||||
|
||||
|
||||
<p><em>I picked <code>#2</code> and <code>14</code> myself, you can configure them in the sketch.</em></p>
|
||||
|
||||
<h3>Preparing your IDE</h3>
|
||||
|
||||
<p>Follow <a href="https://github.com/esp8266/Arduino#installing-with-boards-manager">these instructions</a> on how
|
||||
to install and prepare the Arduino IDE for ESP8266 development.</p>
|
||||
|
||||
<p>After you’re done installing, open the Arduino IDE, in the menu click on <code>sketch</code> -> <code>include library</code> ->
|
||||
<code>manage libraries</code> and install the following libraries:</p>
|
||||
|
||||
<ul>
|
||||
<li>PubSubClient by Nick ‘O Leary</li>
|
||||
<li>Adafruit HDC1000</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<h3>Sketch</h3>
|
||||
|
||||
<p>If you have followed the previous steps, you’re all set.</p>
|
||||
|
||||
<ul>
|
||||
<li>Open Arduino IDE and create a new sketch (<code>File</code> -> <code>New</code>)</li>
|
||||
<li>Copy and paste the below sketch to the Arduino IDE</li>
|
||||
<li>Adjust the values line 6 - 14 to match your setup</li>
|
||||
<li>Optional: If you want to connect to an MQTT server without a username or password, adjust line 63.</li>
|
||||
<li>To have the ESP8266 accept our new sketch, we have to put it in upload mode. On the ESP8266 device
|
||||
keep the GPIO0 button pressed while pressing the reset button. The red led will glow half bright to
|
||||
indicate it is in upload mode.</li>
|
||||
<li>Press the upload button in Arduino IDE</li>
|
||||
<li>Open the serial monitor (<code>Tools</code> -> <code>Serial Monitor</code>) to see the output from your device</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<p>This sketch will connect to your WiFi network and MQTT broker. It will read the temperature and humidity
|
||||
from the sensor every second. It will report it to the MQTT server if the difference is > 1 since last
|
||||
reported value. Reports to the MQTT broker are sent with retain set to <code>True</code>. This means that anyone
|
||||
connecting to the MQTT topic will automatically be notified of the last reported value.</p>

<h3>Configuring Home Assistant</h3>
|
||||
|
||||
<p>The last step is to integrate the sensor values into Home Assistant. This can be done by setting up
|
||||
Home Assistant to connect to the MQTT broker and subscribe to the sensor topics.</p>

<p>It’s time for the August release and there is some serious good stuff this time. The core of Home Assistant has gone some serious clean up and a bump in test coverage thanks to <a href="https://github.com/balloob">@balloob</a>. If you’re a developer, make sure you read up on <a href="https://github.com/balloob/home-assistant/pull/251">the deprecation notices</a>. <a href="https://github.com/fabaff">@fabaff</a> did another great round of documentating all the various components.</p>

|
||||
<p><strong>MQTT Support</strong><br>
|
||||
<img src='/images/supported_brands/mqtt.png' style='border:none; box-shadow: none; float: right;' height='50' />
|
||||
The big new addition in this release is the support for the MQTT protocol by <a href="https://github.com/fabaff">@fabaff</a> with some help from <a href="https://github.com/balloob">@balloob</a>. It will now be possible to integrate any IoT device that talks via MQTT. For the initial release we support connecting Home Assistant to a broker (no TLS yet). Components can now subscribe and publish to MQTT topics (<a href="https://github.com/balloob/home-assistant/blob/dev/config/custom_components/mqtt_example.py">see the example</a>) and also support for the automation component <a href="/components/automation.html#mqtt-based-automation">has been added</a>. For more information, see <a href="/components/mqtt.html">the MQTT component page</a>.</p>
