Nanoleaf's Thread Bulbs Get Apple Adaptive Lighting. Update Them From the App

Spec bumps usually don't change anything you'd notice. This one does. Nanoleaf's firmware 5.1.45 for its Matter-over-Thread lights adds Apple Adaptive Lighting, the feature that shifts your lights from cool white during the day to warm white at night, on its own.

If you use Apple Home with Nanoleaf's Matter-over-Thread bulbs, this is a nice upgrade. Getting it installed takes some care, though.

What Nanoleaf shipped

From Nanoleaf's firmware release notes, 5.1.45 is dated October 7 and applies to "ALL MATTER OVER THREAD DEVICES." Three changes:

• "Apple Adaptive Lighting can be now used natively within the Apple Home app."
• Added support for Matter 1.4.
• Better connection stability in the Nanoleaf app.

The version chart lists it for Matter-over-Thread bulbs (A19 and BR30), downlights, GU10s, and lightstrips. It was added to Nanoleaf's page on October 13.

Why Matter 1.4 is the part that matters

Matterhome.io's write-up has the clearest explanation of why this works now and didn't before. According to Apple's requirements as Matterhome describes them, in iOS 26 and later, Apple Home makes Adaptive Lighting available by default to Matter lights that support Matter 1.4 or later and can reach at least 2700 to 5000 K. Nanoleaf rates its Matter A19 bulbs at 2700 to 6500 K. The color range was already there. Matter 1.4 was the missing piece.

So: you need iOS 26 or later on your iPhone, and the light has to be on 5.1.45. Matterhome notes the previous firmware for these lights was 4.1.3. If a light still says 4.1.3, it hasn't updated.

Who doesn't get it

Two groups of Nanoleaf owners are outside this one.

Matter-over-Wi-Fi lights run a separate firmware line. Nanoleaf moved them to Matter 1.4.2 in firmware 5.2.54 on September 23, and 5.2.59 on October 19 fixed uneven animations. Neither release mentions Adaptive Lighting. They meet the Matter version requirement on paper, so it may show up in Apple Home, but Nanoleaf isn't promising it.

Older Essentials bulbs and lightstrips that use HomeKit over Thread without Matter stay on 3.0.2.

One more thing that trips people up. Matter 1.4 is not Thread 1.4. Nanoleaf's notes say nothing about Thread, and Matterhome cites a SmartThings community report that updated lights still run Thread 1.3.

Update from the Nanoleaf app

Nanoleaf's documented path is its own app: More, then My Devices, start the update, keep the app open, and keep your phone near the light. The update goes over Bluetooth, so "near" means a few meters.

Update the app first. Version 12.0.0 is the first to list "support for firmware 5.x.x on Nanoleaf Matter over Thread devices." Per Matterhome, it started rolling out on Android on October 20 and iOS on October 21.

Then budget some time. Matterhome relays a SmartThings community owner who updated 12 lights and said each took 5 to 10 minutes. Some needed more than one try. Two had to be removed and re-added in both the Nanoleaf and SmartThings apps, which broke that owner's routines. That's one person's experience, but it's the kind of thing I'd plan for.

Home Assistant owners: skip the update button

Home Assistant will offer you this update over Matter. Matterhome reports that since October 12, Home Assistant forum users with A19 bulbs, GU10s and downlights have seen the transfer run, finish with the old version still installed, and then start over later.

Two posters there pass on reports that the Nanoleaf app's Bluetooth update installs it. It isn't a sure thing: Matterhome also mentions a SmartThings owner with a bulb that wouldn't take the update from either the app or Home Assistant. Still, if your update entity keeps cycling, stop fighting it and use the app.

After the update

Open the light in Apple Home and look for the Adaptive Lighting option. Nanoleaf hasn't said whether lights already in your home pick it up in place or need to be removed and added again. If it's missing after a successful update, I'd contact Nanoleaf support before removing and re-adding lights, since that can break routines.

If you were using the Nanoleaf app's own Circadian Lighting schedule, pick one per light. You don't want two schedules fighting over the same bulb.

What I'd do

I'd update one bulb first, ideally one that isn't in a routine anyone depends on. Confirm it takes 5.1.45, confirm Adaptive Lighting shows up in Apple Home, and check that nothing fell out of SmartThings or Home Assistant. Then do the rest in batches on a weekend, standing next to each light with your phone.

It's a real feature, free, on bulbs you already own. It's also a reminder that Matter's "update once, works everywhere" story still depends on which app you press the button in.
