Aqara hub or bridge

An Aqara hub is mandatory, and Aqara states it plainly in three places including the printed quick start guide: 'Aqara Hub is required to enable Aqara Water Leak Sensor to work with HomeKit technology.' Hubs reported compatible include the M2, M1S, M1S Gen 2, E1, G2H, G2H Pro, Camera Hub G3, M3 and M100 — indicative rather than authoritative, since no first-party hub-by-hub compatibility matrix could be located and Aqara's own support page for this product renders 'No content yet'. Critically, the hub you choose determines which ecosystems you get: only a Matter-bridging hub (M2 on post-2023 firmware, M3, M100, G5 Pro) can republish this sensor into SmartThings, Google Home or Home Assistant. A Home Assistant user running their own Zigbee coordinator can skip the Aqara hub entirely, but that is a community path Aqara does not endorse.[2][3][9][32][34][35][40][41][42][43][63][68][70][72][81][85][89][92]

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?

Setup and sources

Apple Home

The most thoroughly documented and longest-supported path for this device — it is stated on the printed manual, not just a web page, and Apple Home surfaces leak sensors well. Requires iOS 10.3 or later and, as with every path here, an Aqara hub. No hub, no HomeKit.[16][32][34][40][42][63][72][81][89]

Google Home

Aqara contradicts itself on its own product page. The prose description says the sensor is 'Compatible with the Aqara Hub, Apple HomeKit, Google Assistant, and Amazon Alexa', but the structured 'Compatible with' badges immediately alongside list only Aqara, Apple Home, Alexa and IFTTT — Google is absent. Aqara's separate compatible-platforms page shows the products it calls compatible with Google Home, and this sensor is not among them, though it is among those shown for IFTTT. Recorded as partial rather than full precisely because the vendor will not commit on the page selling the product. Separately, Google Home has historically been weak at surfacing sensor state, so 'works' may mean it can trigger a routine rather than that you can ask about it.[5][16][32][35][40][41][47][70][74]

Alexa

Works via account-linking the Aqara Home skill, and Alexa carries Aqara's own compatibility badge on the product page. Two limits: the sensor must be joined to an Aqara hub first, and because the link is cloud-to-cloud, an Alexa routine triggered by a leak depends on the internet being up.[16][32][40]

SmartThings

Not confirmed either way. Aqara does not name SmartThings for this sensor: its product page lists Aqara, Apple Home, Alexa and IFTTT. Samsung's own list of Aqara devices that work with SmartThings names the newer Water Leak Sensor T1, not this one. Aqara's Hub M3 page says the hub passes existing Aqara Zigbee devices on to Matter apps and names SmartThings, but it does not say which sensors.[6][36][45][57][58][59][64][65]

Home Assistant

Home Assistant's own Xiaomi Gateway (Aqara) integration names this sensor, model SJCGQ11LM, and reports leaks from it over your home network. It reads the sensor through a Xiaomi Mijia gateway (lumi.gateway.v2 or v3), not through an Aqara hub: Home Assistant lists the Aqara-branded gateway as unsupported, and says switching on the v2 gateway's local access can be hard, even needing the gateway opened up. A community route also exists: Zigbee2MQTT supports this sensor on a generic Zigbee radio, with no Xiaomi or Aqara hub.[7][30][46][66][73][78][86][87][93]

? 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[16][32][40]

✓ Works without a subscription: Yes.

Vendor account required: Yes — you must create a vendor account to use it. (established from the vendor's own setup steps, where signing in is mandatory before the device can be added)[21][43][68][85][92]

No subscription, and leak alerts are not gated. Aqara's paid cloud tiers cover camera and doorbell video storage only and have no bearing on sensors. Recorded with the honesty caveat that this rests partly on absence: no Aqara statement creating a sensor subscription was found across every page researched, but neither was an explicit pledge that sensors stay free.

Maintenance and offline use[1][2][8]

Where Aqara's own pages disagree

whether the sensor has a sounder of its own

On whether the sensor has a sounder of its own, this page shows no sounder on the sensor; the hub sounds the alarm. Aqara's US store description says this sensor has a built-in buzzer, while its product page and quick start guide say the hub sounds the alarm, so this page says the sensor itself is silent.

Who it's for

Households already inside the Aqara ecosystem with a hub in place, where this is among the cheapest ways to add leak coverage and the fourth and fifth sensor cost almost nothing. Apple Home households get the most thoroughly documented and longest-supported path. Home Assistant users can skip the Aqara hub: Home Assistant's own integration reads it through a Xiaomi Mijia gateway, and users running their own Zigbee radio get a cheap, well-supported Zigbee device. It is the wrong buy for someone purchasing a single leak sensor with no hub — the all-in cost is wrong and the alarm will not be where the water is — for anyone who needs a noise at the leak itself, for anyone shopping specifically for Matter-native hardware, and for SmartThings-first households, because neither Aqara nor Samsung names SmartThings for this sensor.

  4. [4] A csa-iot.org certified-products search filtered to manufacturer Lumi United returned no Aqara water-leak product, while returning Eltako, Grimsholm, Heiman, IKEA KLIPPBOK and Shelly Flood Gen4 for the same device type — so the absence is a filtered negative, not a failed search.

  9. [9] Aqara's Valve Controller T1 pages describe a battery-powered actuator that clamps onto an existing lever or butterfly valve (DN15/20/25) without plumbing work, stating 'Pair it with water leak sensors for automatic shutdown when leaks are detected'; aqara.com/us/product/water-sensor/ separately documents 'Automatically Turns the Water Off When Used with Solenoid Water Valve', and the sensor's probes can be unscrewed and wired to extension cables. The valve controller is a separate purchase and itself requires an Aqara hub, so automatic shutoff is a sensor-plus-valve-plus-hub system, not a $19 fix. ⊕ Upgraded 2026-07-31: this entry previously ended 'The Valve Controller pages were reached via search snippets rather than direct fetch.' Those pages have since been read at first hand and the Valve Controller T1 is now its own record (aqara-valve-controller-t1, $69.99, VC-X01E) — every claim above is confirmed at first-party source, and the caveat is retired rather than left standing after it stopped being true., verified 2026-07-19

  12. [12] Aqara's own materials disagree in several places: Google appears in prose but not in the compatibility badges; IP67 is on the global product page but absent from the US spec sheet; and the T1 spec page prints an operating range of '0 °C ~ 55 °C (14 °F ~ 131 °F)' where 0 °C is 32 °F, a straight conversion error.

The visible page agreed at $18.99 with an add-to-cart flow.

The compliance index separately lists this model's PSTI statement as Active and an EU Data Act statement issued 2025-10-23. RECORDED BECAUSE THE STRONGEST AVAILABLE SOURCE CLASS STILL DID NOT PRODUCE A DATE: a per-product regulatory declaration outranks a general policy table, and this one is signed and model-specific — yet its period is anchored to 'launch day' for a product launched in 2018, so it cannot be turned into a forward date.

The vendor's self-contradiction recorded on 2026-07-19 therefore persists unchanged: Google appears in Aqara's prose and on its platform-overview page (us.aqara.com/pages/explorecompatible-platforms, which lists Google Home among compatible platforms under the caveat 'Hub may be required for certain ecosystems or functionalities') while being absent from the badges on the page that sells the product. That is why the Google cell stays partial rather than full — re-verified, not merely carried forward. On subscription: the product page shows no plan, no gated capability and no upsell of any kind, and the page's own feature list presents app alerts and hub-siren triggering as included.

Outcome: no integration level moved, no protocol moved, and the price figure is unchanged. What changed is why the price is that figure (the discount is gone, so $18.99 is now list), and the security-support axis went from empty to a sourced explanation of why no date exists. — Re-checked this against its sources, verified 2026-08-12

Where sources disagree

Where two sources we consider reliable say different things, we publish both positions and what we recorded, rather than quietly picking one.

Google Home compatibility

We publish: partial

Aqara contradicts itself on its own page, so neither statement can be treated as more authoritative than the other. We published "partial" because it is the only answer both sources support: Aqara's platforms page does describe a Google route, while the compatibility badges on the page selling the product leave Google out.

Compatibility and lifecycle information reflects the last-verified date above and can change without notice (firmware updates, cloud-service changes, discontinuations). It is provided as-is, for information — verify with the manufacturer before purchasing. Spot an error? Tell us and we'll fix it. Full terms: Terms of Service.
