IKEA has never been subtle about its smart home ambitions, and the new KAJPLATS bulb range — part of a sweeping 21-device Matter-over-Thread rollout — makes a very loud statement: good smart lighting doesn't have to cost a fortune. But there's more going on under that frosted glass than the price tag suggests.

What Actually Changed From TRÅDFRI

If you're upgrading from IKEA's older TRÅDFRI Zigbee lineup, the headline improvements are a brighter output range and full Matter-over-Thread support. Eleven variants cover everything from colour-changing bulbs to white spectrum dimmables, so there's a shape and size for most fixtures. The move to Matter means these bulbs work natively with Apple Home, Google Home, Amazon Alexa, and Home Assistant — no IKEA gateway required for basic setup.

That said, the loss of a dedicated Zigbee line has frustrated longtime users who built entire automations around it. Here's the genuinely exciting twist though: the community has discovered that the KAJPLATS bulbs run on Qorvo chips that support multiple protocols simultaneously. A specific on/off reset cycle (12 times from off) reportedly puts the bulb into Zigbee pairing mode. The BILRESA remote is already confirmed for Zigbee2MQTT support in early 2026. For Zigbee enthusiasts, this line may be more future-friendly than IKEA is letting on publicly.

The Price Point Is the Real Story

Community reaction to the pricing has been almost uniformly positive — and that's rare. At UK prices, remote controls are around £3, temperature/humidity sensors around £5, and motion sensors around £7. Bulb pricing isn't officially confirmed in the source material, but the sensor pricing alone sets a benchmark that competitors like Aqara or Eve routinely charge two to three times more to match.

One r/HomeKit commenter put it simply: "No reason a simple sensor should be over $10." The broader consensus across Reddit communities is that IKEA has undercut the market on sensors and accessories specifically, making the ecosystem compelling even if you just want a few automations without building a serious smart home.

The Ecosystem Around the Bulbs

The KAJPLATS bulbs are the anchor of a surprisingly complete new collection. Paired with the MYGGSPRAY motion sensor (yes, that translates to "mosquito spray"), BILRESA remotes with a scroll-wheel option, and the GRILLPLATS smart plug, you can build a genuinely capable home automation setup at a fraction of what Philips Hue or Lutron would cost. The air quality sensor (ALPSTUGA) even integrates with IKEA's own purifiers and displays CO2, PM2.5, temperature, and humidity — with a clock built in.

What's missing? Wall switches. Multiple users in the HomeKit and Home Assistant communities specifically called this out — there's still no clean, non-touch-panel wall switch in the lineup. If you want proper physical controls beyond the remote, you're still looking at third-party solutions. Blinds were also conspicuously absent, which frustrated users whose old IKEA smart blinds were discontinued, leaving them with an orphaned hub.

Matter: The Platform That Makes This Actually Work

The shift to Matter-over-Thread is genuinely significant. Thread creates a low-power mesh network that's more reliable than Wi-Fi bulbs and faster to respond than Bluetooth. With a Thread Border Router (built into newer Apple TV 4K, HomePod mini, and some Amazon Echo devices), these bulbs can operate without any IKEA hub at all. For Home Assistant users specifically, Thread support means local control with no cloud dependency — which the HA community values highly.

The caveat: if you don't already have Thread infrastructure, you'll need a border router. IKEA's own gateway works too, but part of Matter's appeal is that it shouldn't matter which ecosystem you're in. Early adopters should verify their Thread setup before expecting seamless onboarding.

Who Should Buy These

These bulbs make the most sense for three types of buyers:

• Budget-conscious smart home starters who want Matter compatibility without the Philips Hue tax
• Home Assistant / Zigbee2MQTT users willing to explore the Zigbee pairing workaround for local control
• TRÅDFRI upgraders who want more brightness and modern protocol support while staying in the IKEA ecosystem

If you need dedicated wall switches, smart blinds, or are heavily invested in a non-Matter ecosystem with no plans to migrate, hold off or supplement with other brands.

The One Legitimate Concern

Dropping Zigbee as an official supported protocol stings. IKEA's reasoning is understandable — standardizing on Matter simplifies support — but the community workaround (unofficial Zigbee pairing via reset cycles) is not something IKEA is backing with documentation or guarantees. If Zigbee reliability matters to your setup, you're betting on community reverse-engineering remaining stable across firmware updates. That's a real risk worth naming plainly.

Frequently Asked Questions

Q: Do the IKEA KAJPLATS bulbs require the IKEA hub?

A: No. As Matter-over-Thread devices, they work with any Thread Border Router, including Apple TV 4K, HomePod mini, and select Amazon Echo devices. An IKEA hub is optional.

Q: Do the new IKEA Matter bulbs still support Zigbee?

A: Not officially, but community testing has confirmed the KAJPLATS bulbs can be put into Zigbee pairing mode via a 12-cycle on/off reset. The chips (Qorvo) support both protocols, and Zigbee2MQTT support for the BILRESA remote is confirmed for early 2026. This is unofficial and may change with firmware updates.

Q: How do IKEA KAJPLATS bulbs compare to Philips Hue?

A: Both now use Matter, but IKEA is significantly cheaper across the board. Philips Hue has a more mature ecosystem, better app polish, and a wider accessory range including wall switches. IKEA wins on price-to-feature ratio for casual and budget users.

Q: Are the new IKEA smart bulbs brighter than TRÅDFRI?

A: Yes. IKEA explicitly states improved brightness range compared to the TRÅDFRI series, though exact lumen figures per variant haven't been broadly published in community discussions yet.

Q: What Thread Border Router do I need for IKEA Matter bulbs?

A: Any certified Thread Border Router works — Apple TV 4K (3rd gen), HomePod mini, HomePod (2nd gen), Amazon Echo (4th gen), or the IKEA DIRIGERA hub. Home Assistant with a compatible USB Thread radio also works.
