Before you buy

What do you need to make it work?

No hub for the device alone

Choose a platform above for its connection. A hub can be optional for the device itself and required for a platform or automation.

Not to use it from an iPhone or iPad, and yes for anything automatic or away from home. Eve says 'This device does not require a hub for control right from your iPhone or iPad.' and that a hub unlocks remote access, automations, notifications and Thread, naming 'HomePod (2nd gen), HomePod mini or Apple TV 4K (2nd gen/3rd gen 128 GB)'. Its requirements add 'Notifications away from home require a home hub'. Setup needs an iPhone or iPad; there is no Android path.[3][29][33][42][49][51][53][55][61][66]

Equipment that adds features

Check which features need it

Apple hub or bridge

A HomePod (2nd gen), HomePod mini or Apple TV 4K (2nd gen, or the 3rd gen 128 GB model), in Eve's words. Eve says the sensor needs no hub for control from an iPhone or iPad, and that a hub adds remote access, automations, notifications and Thread; its requirements add that notifications away from home need one.[3][29][33][42][49][51][53][55][61][66]

Check which features need it

Thread border router

Eve says the only other thing the sensor needs for Thread is 'a home hub (Thread border router)', so in an Apple home the HomePod or Apple TV above is also what puts it on Thread. Without one it talks to your iPhone or iPad over Bluetooth.[3][29][33][42][49][51][53][55][61][66]

One device can provide more than one role. These are setup requirements, not a shopping list of separate purchases.

What could you do with this?

Put its functions to use.

Research, not hands-on testing

Start with a documented control or event. The selected connection shows what is confirmed for that platform.

Setup and sources

Apple Home

The one ecosystem this device serves, and it serves it fully — but the useful half needs hardware beyond the box. Remote notifications, away-from-home alerts and automations all require a HomePod or Apple TV, so the real entry cost is above the sticker for anyone who does not already own one. It is a Full Thread Device and, being mains-powered, acts as a router that extends the Thread mesh rather than leaning on it. Siren muting is missing from the Apple Home app and lives only in the Eve app.[1][14][42][50][55][62]

Google Home

Eve publishes the control path for this leak sensor as a closed set: 'Eve Water Guard can be controlled using the Eve app, the Home app and Siri.' The feature table under that sentence has exactly three columns — Eve app, Home app, Siri — and every capability is ticked under those three. Google Home is in neither. The sensor speaks Apple's HomeKit language over Thread and Eve offers no Matter upgrade for it, so there is no route from Google Home to reach it.[26][42][55]

Alexa

Eve publishes the control path for this leak sensor as a closed set: 'Eve Water Guard can be controlled using the Eve app, the Home app and Siri.' The feature table under that sentence has exactly three columns, Eve app, Home app and Siri. Alexa is in neither. The sensor speaks Apple's HomeKit language over Thread and Eve offers no Matter upgrade for it, so Eve gives no route from Alexa to it.[5][18][54]

SmartThings

Not established. Neither Eve nor SmartThings publishes anything about this leak sensor that settles it either way. What is known: the sensor speaks Apple's HomeKit language over Thread, Eve offers no Matter upgrade for it, and SmartThings does not speak HomeKit — so a working SmartThings path is unlikely, and we have no statement from either company saying so. If you run SmartThings, plan on Apple Home for this sensor and check with Eve before you buy.[32]

Home Assistant

Home Assistant's HomeKit Device integration adds it locally, and Apple lists Eve Water Guard among the accessories that work with its Home app. Home Assistant's page does not list leak sensors among what that integration shows, so the leak alert is unconfirmed. Thread needs a border router, and Home Assistant can hold it only after you remove it from the Apple Home app, because a HomeKit accessory pairs with one controller at a time. Home Assistant's Eve integration covers Eve's Matter products and does not list Water Guard.[7][36][39][40][41][48][49][50][53][62][65][66]

? Inconclusive means we researched that ecosystem and the evidence doesn’t settle it — the catch says why, and the sources are listed below. It is a statement about the available evidence, never a verdict on the product. A Setup Check researches your exact setup where the official sources don’t answer.

Plans and ongoing costs[8][28][45][52][58]

✓ Works without a subscription: Yes.

Vendor account required: No — no vendor account is involved.[8][28][45][52][58]

No subscription and no vendor account at all — Eve states there is no Eve cloud or bridge, and settings sync through the buyer's own iCloud rather than an Eve server. This is verified from Eve's privacy and product pages, not assumed from silence.

Maintenance and offline use[3]

Who it's for

Apple Home households that already own a HomePod or Apple TV and need to watch a long linear run — behind a washer, along a water heater drip pan, down a length of exposed pipe — rather than one point on a floor, and that specifically want a device with no vendor account or cloud behind it. It is the wrong product for Android households, for anyone mixing ecosystems, and for anyone who needs the sensor somewhere far from an outlet.

Supported by a csa-iot.org certified-products search that returned six other Eve devices and no Water Guard entry, and by Home Assistant's Eve integration page, which is Matter-only and does not list it. VERIFICATION NOTE: a search snippet asserting 'Eve Water Guard is Matter-enabled' was traced to generic Eve marketing boilerplate conflated with Water Guard content by the search engine, and is contradicted by four Eve-owned pages — treat that claim as a known false positive if it resurfaces. — Read on the maker's own site, verified 2026-07-19

  14. [14] evehome.com/en-us/eve-water-guard, read 2026-08-12. THE PRICE IS STILL NOT PUBLISHED, and that is the finding rather than a gap in the research: the page carries an add-to-cart flow and the line 'Only available at the Eve Store', with no figure anywhere on it. So the recorded $99.95 remains what it has always been — the February 2022 launch figure, the last price Eve itself published for this model — and it is NOT re-stamped as a current price, because nothing current was observed. A confirmed absence is a real outcome of re-checking — we record why a value is what it is — and this one has now held across two consecutive checks a month apart. Compatibility re-read on the same page: the 'Works with Apple Home' badge is present and no other ecosystem appears, which is why Alexa, Google and SmartThings stay recorded as not supported rather than unknown — Eve names one platform and only one. Thread is stated ('Alongside Bluetooth, Eve Water Guard supports Thread') and Matter readiness is described, both matching the recorded protocols.
