How to Use OIO with Apple Home: Complete Setup Guide

Updated March 2026 · Circadian Lighting Lab · 12 min read

OIO by Korrus is the only spectrally engineered circadian bulb that supports Matter — which means it works natively with Apple Home. No bridge. No third-party app workaround. No cloud dependency. You scan a QR code, and the bulb shows up in the Home app like any other HomeKit accessory.

This guide walks through every step: initial pairing, scene creation, time-of-day automations, Focus mode integration, Siri commands, multi-room setup, and advanced Shortcuts workflows. If you're in the Apple ecosystem and you want circadian lighting that actually works, this is the playbook.

Why this combination matters. Most circadian bulbs either lack smart home support entirely (Hooga, Bon Charge) or only work with Alexa and Google (NorbSMART). OIO's Matter support means Apple Home users — historically underserved by circadian lighting products — can build a fully automated circadian system using the tools they already have: the Home app, Siri, Focus modes, and the Shortcuts app. No extra hubs or ecosystems required.

What Makes OIO + Apple Home Special

Before we get into setup, it's worth understanding why this pairing is more than just "smart bulb meets smart home."

OIO by Korrus has four spectrally engineered modes — MaxBlue (morning), Daylight (midday), ZeroBlue with Violet (evening), and Deep Warm at 1400K (night). These aren't color temperature presets. They're distinct spectral recipes where the actual wavelengths change at the chip level. In evening mode, blue wavelengths are physically removed from the output. Research with Satchin Panda at the Salk Institute measured 68% more melatonin production under OIO's evening spectrum compared to standard LEDs.

OIO supports Matter, the universal smart home protocol that Apple co-developed. Matter devices connect to Apple Home without proprietary bridges, without cloud accounts, and without reliability concerns tied to third-party servers. The bulb communicates locally through your Apple Home hub (Apple TV, HomePod, or iPad), which means automations fire even if your internet goes down.

This gives you two layers of circadian control:

  1. OIO's built-in schedule — Set your wake and sleep times in the Korrus app, and the bulb cycles through all four spectral modes automatically. This runs on the bulb itself.
  2. Apple Home automations — Layer on scenes, Focus mode triggers, sunrise/sunset timing, and Siri commands for additional control and integration with your broader smart home.

The two layers complement each other. The bulb's internal schedule is your reliable foundation. Apple Home adds context-aware intelligence on top.

Step 1: Add OIO to Apple Home via Matter

The initial pairing takes about two minutes per bulb. Here's the process:

What you need

  • OIO bulbs — available at korrus.com in 2-packs, 4-packs, and 10-packs
  • An Apple Home hub — Apple TV (4th generation or later), HomePod, HomePod mini, or an iPad set up as a home hub
  • A 2.4GHz WiFi network — OIO connects via 2.4GHz WiFi, not 5GHz (more on this in the troubleshooting section)
  • iPhone or iPad running iOS 16.1 or later (for Matter support)

Pairing process

  1. Screw in the bulb and turn it on. OIO enters pairing mode automatically when first powered on. You'll see the bulb cycle through a brief color sequence to indicate it's ready.
  2. Open the Home app on your iPhone or iPad.
  3. Tap the "+" button in the upper right corner, then select "Add Accessory."
  4. Scan the Matter QR code. You'll find it on the OIO packaging and on a card included in the box. Hold your camera over the code — the Home app will recognize it as a Matter device.
  5. Assign the bulb to a room. The Home app will prompt you to choose a room (Bedroom, Living Room, etc.) or create a new one. Pick the room where the bulb is physically installed.
  6. Name the bulb. Use something descriptive: "Bedroom Ceiling," "Living Room Lamp," "Nightstand." Good naming makes Siri commands much more natural.
  7. Wait for the setup to complete. The Home app will configure the bulb over your local network. This usually takes 15–30 seconds.

Once paired, the bulb appears in Apple Home with controls for on/off, brightness, and color temperature. You can adjust these manually, but the real power comes from scenes and automations.

Tip: Set up OIO's internal schedule first. Before diving into Apple Home automations, open the Korrus app separately and configure your wake/sleep times. This sets the bulb's built-in 4-mode circadian schedule as your baseline. Apple Home automations will layer on top — giving you both the spectral precision of OIO's internal modes and the contextual intelligence of Apple's automation platform.

Step 2: Create Circadian Scenes

Scenes in Apple Home let you set multiple accessories to specific states with one tap or one voice command. For circadian lighting, you want four core scenes that map to OIO's spectral modes.

Morning Scene: "Good Morning" or "Wake Up"

Open the Home app → tap "+" → "Add Scene" → "Custom." Name it "Good Morning."

  • OIO bulbs: On, maximum brightness, 6500K (MaxBlue range)
  • Other accessories: Open smart blinds, start the coffee maker, set thermostat to daytime temperature — whatever fits your morning

This scene delivers the bright, blue-enriched light your circadian clock needs first thing in the morning. OIO's MaxBlue mode pushes over 20% blue spectral content — the signal that suppresses residual melatonin, drives the cortisol awakening response, and tells your body the day has started.

Daytime Scene: "Work Mode" or "Daylight"

  • OIO bulbs: On, 80–100% brightness, 5000–5500K (balanced daylight)
  • Other accessories: Adjust as needed for your work routine

Balanced, full-spectrum light for the midday hours. Good color rendering for video calls and focused work. Not as aggressively blue as the morning scene, but still bright enough to maintain alertness.

Evening Scene: "Wind Down" or "Evening"

  • OIO bulbs: On, 50–70% brightness, lowest color temperature available (ZeroBlue range)
  • Other accessories: Close smart blinds, dim any non-OIO lights, set thermostat to evening temperature

This is where OIO earns its price. In this mode, blue wavelengths are removed from the spectral output. The light looks warm and comfortable — thanks to retained violet wavelengths, it doesn't have that sickly amber look — but your circadian photoreceptors receive no melatonin-suppressing signal. Dim-light melatonin onset (DLMO) proceeds naturally.

Bedtime Scene: "Goodnight" or "Sleep"

  • OIO bulbs: On at very low brightness, deepest warm setting (~1400K), or off entirely
  • Other accessories: Lock doors, arm security system, turn off TV, set thermostat to sleep temperature

Deep amber at minimal brightness for the last 30–60 minutes before sleep. Think candlelight. The goal is wayfinding light — enough to not trip, not enough to read. Or, if you prefer total darkness, set the bulbs to off in this scene and rely on a separate OIO in a hallway or bathroom for any nighttime navigation.

The OIO advantage in scenes. Here's what most people miss: because OIO does its spectral engineering at the bulb level, even a simple on/off scene delivers circadian benefits. Set your Evening scene to just "turn on OIO" and you're already getting blue-free light. With Philips Hue, you'd need to specify exact color temperature, hope the CCT shift actually reduces blue (it doesn't — the blue spike persists), and build much more complex scenes for inferior results. OIO makes Apple Home automations radically simpler because the bulb itself is doing the hard work.

Step 3: Automate by Time of Day

Scenes are great for manual control. Automations make them run without you thinking about it.

In the Home app, go to the Automation tab → "Create New Automation" → "A Time of Day Occurs."

Recommended automation schedule

Trigger Scene What Happens
6:30 AM (or your wake time) Good Morning OIO MaxBlue at full brightness. Blue-rich light to anchor circadian clock.
10:00 AM Work Mode OIO Daylight mode. Balanced spectrum for focus and alertness.
Sunset (or sunset − 30 min) Wind Down OIO ZeroBlue. Blue wavelengths removed. Melatonin production begins naturally.
9:00 PM (or 1 hour before bed) Goodnight OIO Deep Warm 1400K at low brightness, or off.

Using sunrise and sunset triggers

Apple Home lets you set automations to trigger at sunrise or sunset, with offsets of up to several hours before or after. This is particularly valuable for the evening transition — sunset varies by over 5 hours across the year at most latitudes, and your circadian system naturally follows the solar cycle.

For the Wind Down scene, "sunset" with a 0–30 minute offset is more biologically appropriate than a fixed 5:00 PM trigger. In summer, you get blue-free light starting at 8:30 PM. In winter, it kicks in at 5:00 PM. Both match the natural light cycle your body expects.

For the morning, sunrise-based triggers work well if your wake time is flexible. If you wake by alarm at a fixed time regardless of season, stick with a fixed time trigger.

Step 4: Integrate with iPhone Focus Modes

This is where the Apple ecosystem really shines. Focus modes on iPhone (Sleep, Do Not Disturb, Work, Personal, etc.) can trigger Home automations — meaning your lighting automatically adjusts based on what you're doing, not just what time it is.

Sleep Focus → Evening Lighting

This is the highest-value integration. When your Sleep Focus activates (either on your scheduled sleep wind-down time or manually), it triggers your Wind Down or Goodnight scene.

To set this up:

  1. Open Settings → Focus → Sleep on your iPhone.
  2. Under your Sleep schedule, set your Wind Down time (e.g., 9:00 PM).
  3. In the Home app, create an automation: "When" → "A Sensor Detects Something" isn't needed here. Instead, use the Shortcuts app (covered below) to link Focus activation to a Home scene.

Alternatively, in iOS 17+, you can directly tie Home scenes to Focus modes:

  1. Open Settings → Focus → Sleep.
  2. Scroll to "Customize Screens."
  3. Under "Home Screen" or "Filters," look for the Home section.
  4. Select the scene you want triggered when Sleep Focus activates.

The result: when your iPhone's Sleep Focus turns on at your scheduled wind-down time, your OIO bulbs throughout the house automatically switch to blue-free evening mode. You don't touch anything. Your phone's bedtime routine and your home's lighting become synchronized.

Work Focus → Daylight Mode

If you work from home, tie your Work Focus to the Daylight scene. When you start your work focus (manually or on a schedule), your home office OIO bulbs switch to bright, balanced daylight. When work focus ends, they transition to evening mode.

Do Not Disturb → Deep Warm

Some people use DND as their late-night mode. Link it to the Goodnight scene so that activating DND also drops your lighting to the deepest amber.

The Focus mode philosophy. Focus modes transform lighting from schedule-based to context-based. Schedule-based works for routine days. But what about the Friday night you stay up late? The Sunday morning you sleep in? Focus modes let the lighting follow your actual behavior, not a rigid clock. Tap "Sleep Focus" whenever you're winding down, whether that's 9 PM or midnight, and the lighting responds.

Step 5: Set Up Siri Commands

Once your scenes are configured, Siri already knows about them. Every scene name becomes a voice command.

Built-in Siri commands

  • "Hey Siri, Good Morning" — triggers the Good Morning scene (OIO MaxBlue, full brightness)
  • "Hey Siri, Wind Down" — triggers the Evening scene (OIO ZeroBlue)
  • "Hey Siri, Goodnight" — triggers the Bedtime scene (OIO Deep Warm or off)
  • "Hey Siri, turn off all lights" — turns off every bulb in the home
  • "Hey Siri, set Bedroom to 20%" — dims OIO bulbs in the Bedroom room to 20%
  • "Hey Siri, turn on the Living Room" — turns on all accessories in the Living Room

Room-specific commands

If you've assigned bulbs to rooms properly, Siri understands room context:

  • "Hey Siri, turn off the Bedroom lights" — only affects bedroom bulbs
  • "Hey Siri, dim the Living Room to 30%" — only dims living room bulbs
  • "Hey Siri, make the Office brighter" — increases brightness in the office only

Naming tips for better Siri recognition

Keep bulb and scene names short and distinct. "Bedroom Ceiling" works better than "Master Bedroom Overhead Fixture." Avoid names that sound similar to each other. If Siri consistently misinterprets a scene name, rename the scene to something phonetically clearer.

HomePod and HomePod mini are particularly good for voice-controlled lighting because they're always listening (no need to grab your phone) and they're already your Apple Home hub, so the response is near-instant.

Step 6: Configure Multi-Room Zones

For a whole-home circadian setup, you want OIO bulbs assigned to the right rooms and organized into zones for coordinated control.

Recommended room setup

Room OIO Bulbs Priority Notes
Bedroom 2–3 (overhead + bedside) Tier 1 Most critical room. Last light before sleep, first light at wake.
Living Room 2–4 (overhead + lamps) Tier 1 Where you spend the evening hours. High-lux exposure during DLMO window.
Bathroom 1–2 (vanity or overhead) Tier 2 Prevents the 2 AM melatonin ambush from bright vanity lighting.
Home Office 1–2 (desk + overhead) Tier 2 Bright daylight during work hours. Evening mode if you work late.
Kitchen 1–2 Tier 3 Nice to have, especially if you cook/eat dinner under bright lights.

The OIO 10-pack ($299.99) covers a typical 3–4 room setup. The 4-pack ($129.99) handles bedroom + living room, which captures roughly 90% of the circadian impact. See our full setup guide for room prioritization details.

Using Apple Home zones

Zones in Apple Home let you group rooms for coordinated control. Useful configurations for circadian lighting:

  • "Upstairs" zone (bedroom + bathroom) — "Hey Siri, turn off Upstairs" when heading to bed
  • "Downstairs" zone (living room + kitchen + office) — switch the whole floor to evening mode at once
  • "Whole Home" — Apple Home's default grouping lets you control all lights simultaneously with "Hey Siri, turn off all lights"

To create a zone: Home app → tap the room name → Room Settings → Zone → select or create a zone. Once configured, Siri and automations can target zones just like individual rooms.

Step 7: Advanced Automations with the Shortcuts App

The Home app handles basic time-of-day automations well. For more sophisticated logic, the Shortcuts app unlocks significantly more power.

Sunrise/sunset-adaptive schedule

Create a Shortcut that checks the current time relative to sunrise and sunset, then activates the appropriate scene. Run it as a Personal Automation triggered at specific times or when you arrive home.

Example Shortcut logic:

  1. Get current weather (which includes sunrise/sunset times for your location)
  2. If current time is between sunrise and sunrise + 3 hours → activate "Good Morning" scene
  3. If current time is between sunrise + 3 hours and sunset − 1 hour → activate "Work Mode" scene
  4. If current time is between sunset − 1 hour and bedtime → activate "Wind Down" scene
  5. If current time is after bedtime → activate "Goodnight" scene

Arrive Home automation

Create a Personal Automation that fires when you arrive home. It checks the time of day and activates the appropriate circadian scene. Coming home at 2 PM? Daylight mode. Coming home at 8 PM? ZeroBlue evening mode. The lighting matches the time automatically.

  1. Shortcuts app → Automation → Create Personal Automation → "Arrive" → select Home location
  2. Add "Get Current Weather" action to determine sunset time
  3. Add "If" conditions based on current time vs. sunset
  4. Set the appropriate Home scene in each branch

Weekend vs. weekday schedules

Your circadian lighting should ideally stay consistent (social jet lag is real), but if your weekend wake time is later, you can build a Shortcut that checks the day of the week and adjusts the morning scene trigger accordingly. A 30–60 minute delay on weekends is fine. Two or more hours of shift starts to undermine your circadian rhythm.

Focus mode + Shortcuts integration

For the cleanest Focus mode → lighting integration, create a Personal Automation in Shortcuts:

  1. Shortcuts app → Automation → "Create Personal Automation"
  2. Select "Sleep" as the trigger (this fires when your Sleep Focus activates)
  3. Add "Control [Home name]" action → select "Wind Down" scene
  4. Toggle "Run Immediately" (so it doesn't require confirmation)

This is the most reliable way to link Focus modes to Home scenes, and it works consistently on iOS 17 and later.

Keep it simple to start. If you're new to Apple Home automations, begin with just the four time-based scenes. Don't build complex Shortcuts until the basic schedule is working and you've lived with it for a week. The biggest advantage of OIO is that the bulb itself handles spectral transitions — Apple Home automations are an enhancement, not a requirement. The bulb's built-in schedule is your safety net even if an automation misfires.

Why OIO + Apple Home Beats Philips Hue for Circadian Lighting

Philips Hue is the most popular smart lighting platform in the world, and it has deep Apple Home integration. So why not just use Hue for circadian lighting?

The short answer: Hue shifts color temperature. OIO shifts the actual spectrum. The full answer matters enough to spell out.

The spectral difference

When you set a Hue bulb to 2200K in your Apple Home evening scene, the light looks warm and amber to your eyes. But underneath that warm appearance, the LED still emits a spike of blue light around 450–460nm. This is a fundamental property of how standard white LEDs work. Your retinal ganglion cells — the cells that regulate melatonin production — detect that blue spike and suppress melatonin regardless of how warm the light "looks."

OIO's ZeroBlue mode physically removes blue wavelengths from the spectral output at the chip level. There is no blue spike. Your circadian photoreceptors receive no melatonin-suppressing signal. The Salk Institute measured the difference: 68% more melatonin under OIO's evening spectrum compared to standard LEDs.

The automation simplicity difference

With Hue, getting the "best possible" circadian result in Apple Home requires painstaking scene configuration: exact color temperatures, precise brightness levels, careful color selection — and the result is still limited by the hardware. The blue spike remains no matter how carefully you tune the settings.

With OIO, a simple "turn on" command in an evening scene delivers blue-free light automatically. The spectral engineering happens at the bulb, not in the scene configuration. This means:

  • Simpler scenes — You don't need to micromanage color temperature values
  • Fewer failure modes — Even if an automation partially misfires, OIO's internal schedule keeps the spectral mode correct
  • Better results from basic setups — A first-time Apple Home user with OIO gets better circadian outcomes than a Hue power user with perfectly configured scenes

The Hue "circadian" illusion. Hue's third-party circadian apps (like Adaptive Lighting and various Hue Labs formulas) create the appearance of circadian automation by scheduling CCT shifts throughout the day. But CCT shifting on a standard LED does not remove the blue spectral spike. It masks it. Your eyes see a warm scene. Your circadian system still detects blue light and suppresses melatonin. If you already own Hue, it's better than nothing. But if you're buying specifically for circadian benefits, OIO is built for the job and Hue is not.

No hub required

OIO connects directly to Apple Home via Matter over WiFi. Hue requires a $60 Hue Bridge for its full feature set, including scheduled automations. For Apple Home users, OIO eliminates an extra box, an extra power cable, an extra point of failure, and an extra $60.

Troubleshooting

Most OIO + Apple Home setups work smoothly, but here are the issues people occasionally run into and how to fix them.

OIO won't pair: 2.4GHz WiFi requirement

OIO connects via 2.4GHz WiFi, not 5GHz. Many modern routers broadcast both bands under the same network name (SSID), and the phone may be on 5GHz while the bulb needs 2.4GHz.

Fix: Most routers handle this automatically during Matter pairing. If pairing fails, try these steps:

  1. Move your phone closer to the router and the bulb during setup
  2. If your router has separate SSIDs for 2.4GHz and 5GHz, temporarily connect your phone to the 2.4GHz network during pairing
  3. Restart the bulb (power cycle: off for 10 seconds, then on) to re-enter pairing mode
  4. Make sure your Apple Home hub (Apple TV, HomePod) is on the same network

Matter and Thread considerations

Matter is the protocol. Thread is one of the underlying transport layers Matter can use (alongside WiFi and Bluetooth). OIO uses Matter over WiFi, which is the most broadly compatible option — it works with any WiFi router without Thread border routers or additional hardware.

If you have Thread-enabled devices in your home (some HomePod minis, newer Apple TVs), they won't interfere with OIO's WiFi-based Matter connection. The two coexist fine. Thread devices and WiFi devices both appear in the same Apple Home and can be combined in the same scenes and automations.

Bulb not responding after setup

  • Check your Home hub. Apple Home automations require an always-on home hub (Apple TV, HomePod, or HomePod mini). If the hub is off or disconnected, automations won't fire and remote control won't work.
  • Check WiFi signal strength. If the bulb is in a fixture far from your router, weak WiFi can cause intermittent disconnections. A WiFi extender or mesh node near the fixture usually fixes this.
  • Power cycle the bulb. Turn it off at the switch, wait 10 seconds, turn it back on. This resolves most temporary connectivity issues.
  • Re-pair if needed. In the Home app, remove the accessory and re-add it by scanning the Matter QR code again.

Automations not firing

  • Check that automations are enabled. In the Home app → Automation tab, each automation has an on/off toggle. Make sure it's on.
  • Check "People" settings. Some automations have a condition like "When I'm home" or "When nobody's home." If your phone's location isn't being detected correctly, the condition may not be met.
  • Restart the Home hub. An Apple TV or HomePod reboot often resolves automation issues that appear after software updates.

Color temperature not matching expected mode

Remember that OIO has two control layers: its internal schedule (set in the Korrus app) and Apple Home commands. If the Apple Home scene sets a specific color temperature that conflicts with OIO's internal schedule, the most recent command takes priority. For most users, letting OIO's internal schedule run as the baseline and only using Apple Home for scene triggers (on/off, brightness) avoids conflicts.

Still stuck? Korrus has a support team reachable through their website. For Apple Home-specific issues, Apple's Home support documentation covers Matter device troubleshooting in detail. Most issues come down to WiFi connectivity or Home hub configuration — once those are solid, the system is extremely reliable.

The Complete Setup Checklist

Here's the condensed version if you want to get running quickly:

  1. Buy OIO bulbs. 4-pack for bedroom + living room ($129.99). 10-pack for whole home ($299.99). Available at korrus.com.
  2. Confirm your Apple Home hub (Apple TV, HomePod, or HomePod mini) is powered on and connected to WiFi.
  3. Pair each bulb by scanning the Matter QR code in the Home app. Assign to rooms.
  4. Set OIO's internal schedule in the Korrus app (wake time, sleep time). This is your baseline.
  5. Create four scenes in Apple Home: Good Morning, Work Mode, Wind Down, Goodnight.
  6. Automate scenes by time of day. Use sunset offset for the evening transition.
  7. Link Sleep Focus to the Wind Down scene via Shortcuts for context-aware evening lighting.
  8. Test Siri commands. "Hey Siri, Good Morning." "Hey Siri, Wind Down." "Hey Siri, Goodnight."
  9. Live with it for a week. Adjust timing based on your actual routine.

OIO + Apple Home is the best circadian lighting setup for the Apple ecosystem

OIO is the only spectrally engineered circadian bulb with native Apple Home support via Matter. It delivers the spectral precision — including true blue-light removal — that Philips Hue and other smart bulbs cannot physically achieve, wrapped in the Apple Home ecosystem you already use. Four spectral modes, zero extra hubs, Siri control, Focus mode integration, and Shortcuts automation. The bulb handles the circadian science. Apple Home handles the smart home logic.
