Many of us are so deeply consumed by the Apple HomeKit ecosystem that it ends up costing us more to make other parts of homes smart as the HomeKit versions are vastly more expensive than non HomeKit certified versions.
There are also devices that are smart, but just aren’t HomeKit supported.
Fortunately, there’s Homebridge, Homebridge is an app that allows you to run non-HomeKit devices within your HomeKit ecosystem, through the Apple Home app.
A quick example
Problem: I want to use a smart switch to turn a device on and off
Solutions. There are lots of good solutions out there. However only a few are HomeKit compatible.
- Eve Power — £44.95
- TP-Link HS100 — £36.74
- Hive Active Smart Plug — £35.99
(Prices correct as of 15/10/18)
Eve is the obvious choice if you just want out of the box HomeKit compatibility and no faff. However, it is £10 more expensive than the competitors and there are also no multiple discounts should you buy more than one.
So I searched around on the Homebridge repos and found that a plugin for TP Link had been made. This allows me to control those plugs through HomeKit.
Depending on how many plugs you want to turn smart, this can end up saving you a lot of money.
Installing Homebridge
Things that you’ll need:
- Raspberry Pi 3
- Raspberry Pi Charger
- Raspberry Pi Case (Optional)
- USB Keyboard/Mouse
- HDMI TV/Monitor
- Patience (Mandatory)
If you have a computer or NAS that is on permanently in your home it may be worth considering installing Homebridge on that, however I prefer to keep my installation separate and RPi’s use hardly any electricity compared to a computer.
Most Pi’s come pre-installed with NOOBS (New Out Of Box Software)
If yours hasn’t, follow the instructions here.
We’re going to want to ssh into our Pi. We can do that by opening Terminal or CMD.
ssh pi@raspberrypi.localNote that in SSH is disabled by default in recent version of Raspbian; see this page for instructions to re-enable it.
Let’s get everything in order and updated:
sudo apt-get update
sudo apt-get upgradeNext, we’re going to install Node.js, this is what Homebridge runs on.
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejsInstall Avahi and other Dependencies
sudo apt-get install libavahi-compat-libdnssd-devInstalling Homebridge
sudo npm install -g --unsafe-perm homebridgeYou may need to use the –unsafe-perm flag if you receive an error similar to this:
gyp WARN EACCES user "root" does not have permission to access the dev dir "/root/.node-gyp/5.5.0"Now you should be able to run Homebridge:
$ homebridge
No plugins found. See the README for information on installing plugins.Homebridge will complain if you don’t have any Plugins installed, since it will essentially be useless, although you can still “pair” with it. See the next section “Installing Plugins” for more info.
Once you’ve installed a Plugin or two, you can run Homebridge again:
$ homebridge
Couldn't find a config.json file [snip]Homebridge won’t run until we’ve added a config file, so we can create a new one in your homebridge folder, likely to be: ~/.homebridge/config.json
{
"bridge":{
"name":"Homebridge",
"username":"CC:22:3D:E3:CE:30",
"port":51826,
"pin":"031-45-154"
},
"description":"This is an example configuration file with one fake accessory and one fake platform. You can use this as a template for creating your own configuration file containing devices you actually own.",
"accessories":[
{
"accessory":"WeMo",
"name":"Coffee Maker"
}
],
"platforms":[
{
"platform":"PhilipsHue",
"name":"Hue"
}
]
}When editing this make sure you use a plain text (code) editor. Something like Sublime Text or Atom.
Running Homebridge on Bootup (systemd)
We now want Homebridge to run on boot should the Pi get shut down or restarted. To do this we have to turn it into a system service.
sudo nano /etc/default/homebridgeThen paste this
sudo nano /etc/systemd/system/homebridge.serviceThen paste this
Let’s create a user to run the service as
sudo useradd --system homebridgeNow we’ll create a new location for Homebridge
sudo mkdir /var/homebridgeNow we’ll copy the Homebridge installation to the folder
sudo cp ~/.homebridge/config.json /var/homebridge/sudo cp -r ~/.homebridge/persist /var/homebridgesudo chmod -R 0777 /var/homebridgeNow we’ll enable and run the service that we just created
systemctl daemon-reload
systemctl enable homebridge
systemctl start homebridgeWe can now check that it’s all running okay
systemctl status homebridgeIf you need to view logs:
journalctl -f -u homebridgeAdding your Homebridge to Apple Home
Open the Apple Home app on your iOS device and click add, and then add new accessory up the top right. HomeKit will then scan for new devices. If you run:
systemctl status homebridgeThen scroll up you should see a QR code which you can scan with your phone if it hasn’t found your Homebridge device already. It may ask for a pin which is:
031-45-154All done! Your Homebridge hub should now show up in your Home app
We might as well finish our smart plug example
Let’s install the TP-Link plugin
npm install -g homebridge-tplink-smarthomeLet’s navigate to our config.json file using out FTP client and then edit. Under platforms we want to add this code:
"platforms": [{
"platform": "TplinkSmarthome",
"name": "TplinkSmarthome"
}]Save the file. Now we need to restart Homebridge
service homebridge restartCheck that everything has run okay!
systemctl status homebridgeNow go to the Home app on your iOS device and check the room that your Homebridge is present in, you should now see whichever TP Link devices are connected to your network.
