Nanoleaf Ultra Slim 4″ Recessed Downlight
Matter Protocol
The Nanoleaf Ultra Slim 4″ Recessed Downlight from Nanoleaf uses Matter over Thread to connect to your smart home. Thread is a low-power mesh network built for devices like a Ceiling Light. Devices pass messages to each other, so the mesh gets stronger and reaches further with every router you add.
In a Thread network, the Nanoleaf Ultra Slim 4″ Recessed Downlight works as a Router (FTD).
Border Router (TBR)
A Thread Border Router connects your Thread devices to your home network, so no extra hub is needed.
Router (FTD)
A Thread Router stays powered on and relays messages for other devices, extending the range of your network.
End Device (MTD)
A Thread End Device talks to nearby routers and does not relay messages, which saves power and battery life.
Every Thread router you add makes your mesh stronger and extends its range. See all Thread devices →

Frequently Asked Questions
Does the Nanoleaf Ultra Slim 4″ Recessed Downlight need a smart hub?
Yes. The Nanoleaf Ultra Slim 4″ Recessed Downlight needs a Thread Border Router to reach your home network, plus a Matter controller from your platform. Most devices handle both, like a HomePod mini, Google Nest Hub (2nd gen) or Amazon Echo (4th gen). See all border routers
Does the Nanoleaf Ultra Slim 4″ Recessed Downlight work without internet?
Yes. Matter runs on your local network, so the Nanoleaf Ultra Slim 4″ Recessed Downlight keeps working when your internet goes down. Remote access, voice assistants and some Nanoleaf cloud features may still need a working connection.
Does the Nanoleaf Ultra Slim 4″ Recessed Downlight work with Apple Home, Google Home, Alexa and Home Assistant?
Yes. The Nanoleaf Ultra Slim 4″ Recessed Downlight is Matter certified, so it works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, as long as the platform supports Ceiling Light devices. Support for newer device types can differ per platform.
Do I need the Nanoleaf app to use the Nanoleaf Ultra Slim 4″ Recessed Downlight?
No. Any Matter hub can set up and control the Nanoleaf Ultra Slim 4″ Recessed Downlight without the Nanoleaf app. Some advanced features may not be part of Matter yet, so settings like firmware updates or special modes can still require the Nanoleaf app.
How do I set up the Nanoleaf Ultra Slim 4″ Recessed Downlight?
Open your smart home app, choose to add a device and scan the Matter QR code on the Nanoleaf Ultra Slim 4″ Recessed Downlight or its packaging. You can also type in the 11-digit Matter code instead. The app guides you through the rest. Keep the code safe, you need it again after a reset.
