Eve Door & Window (3rd generation, Matter)

Compiled by SmartHomeWorkflow Research · Eve Systems · Sensors & Detectors · ~$43.95 (at time of research — never treated as a live price)

Compatibility

Protocols: THREAD · MATTER^{[1][3][4][5][11]}

Needs before it works: Thread border router + Matter controller — Eve's own wording: 'this Matter-enabled device requires a hub that supports both Thread and Matter.' For Apple Home: HomePod (2nd gen), HomePod mini, or a Thread-capable Apple TV 4K (the Wi-Fi + Ethernet model); for other ecosystems, that platform's Matter controller with Thread border router.^[1][5]

What it can do^[10]

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[1]

✓ Works without a subscription: Yes.

Vendor account required: No — no vendor account is involved.^[12]

Product page states 'No subscription, no registration' and 'No Eve cloud.'

Maintenance reality^[1]

• Batteries: 1/2 AA (ER14250 3.6V) x1
• Works without the internet: Yes — the core function runs on the device or your home network. A vendor cloud may still be involved in remote access.^[9]
• Battery life not stated in Eve's official specs — left unrecorded rather than estimated. The 1/2 AA (ER14250) lithium cell is replaceable but less common at retail than AA/AAA. Firmware updates via the Eve app; the documented Matter-upgrade flow requires iPhone/iPad; the Android Eve app's firmware-update capability is not clearly stated by Eve — unverified.
• Security updates: No security-update support date is on record for this model yet. We haven't yet checked whether Eve Systems publishes one, so this is a gap in our research — not a statement about the manufacturer.

The catch

It is inert without a Thread border router, open/close history requires the Eve app connected through Apple Home, and the 1/2 AA (ER14250) replacement battery is harder to find than standard cells.

Who it's for

Fits homes that already have a Thread border router and want a local, subscription-free contact sensor for doors and windows; Apple Home users additionally get open/close history and duration records.

Price $43.95 UNCHANGED since 2026-07-16, read from this product's own buy-button attribute rather than from a page-wide price grep. All five ecosystem badges re-verified verbatim: 'Works with Apple Home', 'Works with Alexa', 'Works with Google Home', 'Works with Samsung SmartThings', 'Works with Home Assistant'. Subscription claims re-verified verbatim: 'No subscription, no registration' and 'No Eve cloud'.

4. [4] CSA registry re-read from raw markup 2026-08-09, both certificates live (HTTP 200) with a known-positive control (csa_product/aqara-hub-m2/) answering 200 on the same pass, so the instrument was proven before anything was read from it. https://csa-iot.org/csa_product/eve-door-window-2/ → Certificate ID CSA23277MAT40790-24, Certified Date 03/28/2023, Firmware 3.2.0, Vendor ID 0x130A, Product ID 0x004D, Specification Version 1.0, Primary Device Type ID 0x0015, **Transport Interface: 'Thread, Bluetooth'**. https://csa-iot.org/csa_product/eve-door-window-3/ → Certificate ID CSA22068MAT40068-24, Certified Date 11/01/2022, Firmware 3.1.0, same IDs, same Transport Interface. ⚠ The previous citation paired these two certificate IDs with each other's slugs; corrected here — the underlying protocol claim is unaffected. ⚠ **The Bluetooth in the Transport Interface field is COMMISSIONING transport for a Matter-over-Thread device, not a control path**, and `bluetooth` was removed from this record's protocols on 2026-08-09 — the same call made for the Aqara Door and Window Sensor P2 and the Tapo L535E on 2026-08-08. What makes it stronger here than in those cases is that the MANUFACTURER agrees: Eve's product page specification reads 'Wireless Connection: Thread' and never says Bluetooth, and Eve's own generation table reserves 'Bluetooth/Thread' for the 2020 revision. The raw certificate field is recorded verbatim above so the evidence survives whichever way the catalogue-wide rule lands (the split is documented on 16 #101). — registry lookup, verified 2026-08-09
