<h3></h3>
|
||
<p>This is a short tutorial on connecting a zigbee device (an Aqara cube)
|
||
to an MQTT server, so you can control your zigbee devices from the
|
||
network.</p>
|
||
|
||
<p>If you’re anything like me, you’re probably a sucker for IoT devices.
|
||
For a long time, I’ve been using WiFi-enabled lights, and Amazon dash
|
||
buttons to control them. To keep these (cheap Chinese) internet enabled
|
||
devices away from your network and their respective cloud services,
|
||
you’ll probably want to set up a dedicated network in your router (more
|
||
on this on a future post, maybe). Another disadvantage of WiFi devices
|
||
is that they’re relatively power hungry.</p>
|
||
|
||
<p>A popular alternative is using ZigBee for communication. It is a
|
||
dedicated protocol similar to bluetooth (BLE), with lower power
|
||
requirements and bitrate.</p>
|
||
|
||
<p>Take the (super cute) aqara cube as an example. It is a small cube that
|
||
detects rotation on all of its axes, and tapping events. Here’s a
|
||
video:</p>
|
||
|
||
|
||
<div style="position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden;">
|
||
<iframe src="//www.youtube.com/embed/5YtqG1wEnng" style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; border:0;" allowfullscreen title="YouTube Video"></iframe>
|
||
</div>
|
||
|
||
|
||
<p>To connect to zigbee devices you will need a zigbee enabled gateway
|
||
(a.k.a. hub), which connects to your WiFi network and your zigbee
|
||
devices. Once again, this means adding an internet-enabled device to
|
||
your home, and probably a couple of cloud services.</p>
|
||
|
||
<p>As an alternative, you can set up your own zigbee gateway, and control
|
||
it to your home automation platform of choice (e.g. home assistant). We
|
||
will cover how to set up a zigbee2mqtt gateway that is also connected to
|
||
an MQTT server, so you can use MQTT to control your devices and get
|
||
notifications.</p>
|
||
|
||
<p>What you need:</p>

|
||
</ul>
|
||
|
||
<p>You will need to flash your sniffer. For that, you only need to follow
|
||
the instructions from the <a href="https://koenkk.github.io/zigbee2mqtt/">zigbee2mqtt
|
||
documentation</a>.</p>
|
||
|
||
<p>Once you’re done flashing, you’re ready to set up the zigbee2mqtt
|
||
server. For convenience, I wrote a simple docker-compose to deploy a
|
||
zigbee2mqtt server and a test mosquitto server:</p>

|
||
<p>zigbee2mqtt supports the following events for the aqara cube: shake,
|
||
wakeup, fall, tap, slide, flip180, flip90, rotate_left and
|
||
rotate_right. Every event has additional information, such as the sides
|
||
involved, or the degrees turned.</p>
|
||
|
||
<p>Now you are ready to set up home assistant support in zigbee2mqtt
