Compatibility
| Ecosystem | Support | The catch |
|---|---|---|
| Amazon Alexa | WorksWorks with this ecosystem | No Alexa-specific listing exists; coverage rests on IKEA's blanket statement of compatibility with smart systems from Amazon, Apple, Google, Homey and Samsung, via standard Matter with a Thread border router on that platform. |
| Google Home | WorksWorks with this ecosystem | Same basis: IKEA's blanket Matter-systems statement naming Google; no Google-specific listing. Thread border router on the Google side required. |
| Apple Home | WorksWorks with this ecosystem | Same basis: IKEA's blanket Matter-systems statement naming Apple; no Apple-specific listing. Thread border router on the Apple side required. |
| SmartThings | WorksWorks with this ecosystem | Same basis: IKEA's blanket Matter-systems statement naming Samsung; no SmartThings-specific listing. Thread border router on the Samsung side required. |
| Home Assistant | WorksWorks with this ecosystem | IKEA does not name Home Assistant. The path is HA's official Matter integration (local push), which supports sensor entities generically; there is no TIMMERFLOTTE-specific listing on either side. |
Protocols: MATTER · THREAD
Needs before it works: For anything beyond the on-device display: a Matter controller plus a Thread border router — IKEA's page says you need a Thread Border Router to control it through your phone, its DIRIGERA hub the stated example. The press-to-read display itself works with no hub at all; CSA's product description confirms it functions as a standalone device or in a Matter network.
Subscription reality
✓ Works without a subscription: Yes.
No subscription referenced on the IKEA US product page, IKEA's smart-product support policy, or the launch press release.
Maintenance reality
- Batteries: 2x AAA (HR03) 1.2V rechargeable — IKEA recommends LADDA; sold separately, not included
- Cloud dependence: No — core function survives without the vendor's cloud
- Matter over Thread runs locally; IKEA's support policy states smart products keep working, including on local networks without internet, after software support ends. Bluetooth is the commissioning radio (CSA cert). The LED display wakes only on button press, showing temperature then humidity. Battery life is not stated on the US page, so none is recorded. Support duration: at least 5 years after purchase per IKEA policy, conditional on pairing with a DIRIGERA hub or TRADFRI gateway; the policy does not address the term for Matter devices used only with a third-party controller.
The catch
The display is the only thing that works hubless: press the button and it shows temperature then humidity, but app readings, automations, and every ecosystem require a Matter controller plus a Thread border router — and the two required AAA batteries are sold separately.
Who it's for
Anyone who wants a glanceable room thermometer that can later join a Matter ecosystem, and Thread-equipped households adding cheap temperature and humidity triggers for automations.
