The home the place my household at present lives is lit primarily by a bunch of ceiling-mounted recessed bulbs. From high to backside, counting lavatory fixtures, we’ve one thing like 40 lightbulbs in your entire home. And once we moved in, each single a type of lightbulbs was a scorching, power-sucking incandescent bulb. Replacing these bulbs with cooler, more-efficient LEDs was one of many low-hanging dwelling enchancment tasks I took on after we moved in.

As a part of that mission, I lit a few rooms with Philips Hue smartbulbs, which did a ton to popularize and simplify customizable LED lighting once they first got here out again in 2012. These bulbs plus an Ecobee thermostat shaped the muse of a HomePackage setup, chosen as a result of my spouse and I are each iPhone customers and we did not personal an Echo or any Google or Nest merchandise on the time. Since then, our sensible dwelling has grown in matches and begins, accruing totally different devices right here and there and aiming for HomePackage compatibility once we can get it. (I assume a number of sensible dwelling setups are like this—stumbled into over time, made up of a patchwork of merchandise that both got here with the home or have been all purchased individually to fill some particular want, all strapped collectively after the actual fact by Google, Amazon, or Apple, relying on which of the tech giants has you captured most firmly in its tendrils on the time.)

Fast-forward 5 years, and I used to be prepared so as to add sensible lighting to extra rooms in the home. However, I did not wish to pay Hue costs, particularly for the multicolor bulbs—a 60W equal white Hue bulb usually runs about $15, and a full-color bulb prices between $30 and $50 a pop. An organization referred to as meross makes an interesting HomePackage-compatible multicolor bulb for round $15, however middling buyer evaluations (and a dearth {of professional} evaluations) made me hesitate.

I ended up selecting one other Philips bulb model, the utterly totally different and incompatible Wiz lineup (Signify, a Philips spin-off that produces the Hue bulbs, bought an organization referred to as WiZ Connected in 2019, which is the quick clarification for why the identical firm sells two utterly separate traces of sensible bulbs). Wiz bulbs are well-reviewed and price $12 or $13 per multicolored bulb—the one factor they did not do was combine with HomePackage. But for the intrepid DIY-er, there is a answer for this: Homebridge, light-weight server software program that mediates connections between HomePackage and a variety of not-officially-HomePackage-compatible sensible equipment.

Setting up Homebridge

Wiz bulbs may be built-in into Google or Amazon Alexa-powered houses with no points, however outdoors of the Wiz app itself, the bulbs depend on Siri Shortcuts for help on Apple units. In a house that solely used Wiz bulbs, these shortcuts are most likely adequate—you may construct particular person shortcuts to regulate totally different teams of lights just about nevertheless you need. But I needed them to mesh with the Hue bulbs and different equipment I have already got arrange in HomePackage so I can management a mixture of bulbs utilizing the identical instructions, share entry to these instructions with different folks I stay with, and use the identical interface to regulate every part somewhat than a patchwork of various apps.

Homebridge is a nodeJS server that may run on absolutely anything, together with the PC or Mac you already use, or on a Synology or QNAP NAS as a Docker container. By scanning a QR code, you may add your Homebridge gadget to your HomePackage setup as a hub, rather a lot just like the hub that controls Hue lights. From there, HomePackage communicates together with your bridge, and HomeBridge sends these instructions to your non-HomePackage equipment in a language they’ll perceive. Homebridge depends on community-developed plugins for help, and you could find Homebridge plugins for Wiz bulbs, for Nest thermostats and smoke detectors, and even for giving instructions to your HomePackage units by way of Amazon Alexa.

Because I needed one thing low cost and low-power that might simply sit tucked in a nook turned on on a regular basis, I elected to make use of an outdated Raspberry Pi 3 I already had. It was once for game-console emulation, however since I changed it with a Pi 4, it has been languishing in a closet. There’s a ready-made Homebridge picture for the Pi that features the software program and a web-based UI, and that may simply match on any 4GB-or-larger microSD card.

After flashing the Homebridge picture and turning on the Pi, Homebridge will broadcast a Wi-Fi community that you simply connect with with a telephone or pc. This opens a easy web page you utilize to attach HomeBridge to your house Wi-Fi community (it is best to have all of your units on the identical VLAN, which can be how most dwelling networks are configured until you’ve got particularly set it up in any other case; if you happen to put sensible dwelling units on a separate VLAN for safety functions, you can nonetheless use HomePackage and Homebridge with them, however that is a bit past our scope right here).

I then used the Wiz app to get the entire Wiz bulbs joined to my community, which is just about all you want it for if you happen to intend to make use of the bulbs with Homebridge. There’s nothing stopping you from utilizing HomePackage and the Wiz app individually, and the Wiz app has some neat shade presets you may’t actually replicate with the Home app, however I primarily management the bulbs utilizing Siri voice instructions and HomePackage automations.

The captions to the photographs within the gallery above will provide you with a step-by-step walkthrough of putting in the Wiz plugin for Homebridge and ensuring that your entire equipment have been added. Rather than utilizing the QR code on Homebridge’s primary web page so as to add equipment, I additionally desire to create “little one” bridges for every plugin to make Homebridge extra dependable and to make it simpler to isolate issues once they happen. When Homebridge has found your Wiz bulbs on the community and also you add the bridge to HomePackage utilizing the QR code, the entire bulbs ought to present up within the Home app as they usually would. Homebridge and the Wiz plugin even help the brand new “adaptive lighting” function launched in iOS 14, which dynamically adjustments your bulbs’ shade temperature all through the day.

I have not put a ton of effort into securing my Homebridge field, because the Wiz bulbs are the one factor at present related to it and all communication occurs over the native community. There must be no logins or publicity to the open Internet (I’ve experimented with including our Nest Protect thermostats to it however have not carried out a lot past dabbling). You can add 2FA to Homebridge’s login display screen if you happen to like, and I additionally advocate performing some primary Raspberry Pi safety due diligence, like ensuring the default “pi” admin account has its password modified and ensuring the OS requires a password for sudo instructions. You also can allow HTTPS for the Homebridge net interface comparatively simply when you’ve got a certificates. Further safety issues will fluctuate based mostly in your community configuration and the equipment you are utilizing.

This mission hasn’t been completely clean crusing; the Home app and the bulbs generally want a minute to see one another if you happen to flip the bulbs on and off with a light-weight swap, and one unlucky energy outage completely disrupted communication between the bulbs and my Raspberry Pi. I might need been capable of troubleshoot it with sufficient time, however my setup is easy sufficient that I simply reset every part and did it once more. But that is a threat you run with any sensible dwelling DIY mission, and my home wants sufficient bulbs in every room that it is price coping with some complications in trade for a a lot decrease value per bulb.

The Wiz-plus-Homebridge strategy is not going to be for everybody—whether or not you purchase the HomePackage-compatible meross bulbs you determined to skip or simply use Google or Alexa somewhat than HomePackage to tie your entire equipment collectively, there are definitely easier and extra user-friendly choices on the market. But this was a fast, simple, and enjoyable DIY mission that helped me combine my low cost new bulbs with my costly outdated ones and made an outdated Raspberry Pi helpful once more. Homebridge proved to be a purposeful little piece of smart-home software program that is match for many totally different sorts of tasks.
