Save my rear already
Update – 11-29-2023:Added temperature sensor info below and attached image.Original Review:Bought these since they were on sale and wanted something to integrate to Home Assistant. Wasn’t super on board with the idea of a “coin” style water detector (would prefer the cable type), but went with this to give it a shot. I put it next to the drain and water heater downstairs.Fast forward three months. We had a small backup in our drain downstairs and the alarm in Home Assistant went off. Saved me a lot of damage I’m sure. You will 100% want to make sure you set up multiple critical notifications in your automation and consider choosing a custom obnoxious sound. If you’re sleeping, you want to make sure you don’t sleep through it.The Good:– Paid for itself already– Integrated very nicely with my Sonoff receiver in Home Assistant.– Fairly non-descript and small. Hard to notice on the floor.– Fast. This thing went off immediately when water had reached it.– Inexpensive! I’ll be honest, I really wish there was a cable type Zigbee detector that wasn’t $100. But this thing is just so darn inexpensive that you can get six of these for the cost of one of those plus an extension cable.The Cromulent:– It’s battery-powered. As mentioned above, I the cable type is preferred, but I’m guessing there’s zero chance of a cable type without having to be plugged into an outlet. Plus you can put these wherever you need without having to worry about an outlet.– TBD on battery life so far. I’ve been tracking this since I installed it in mid-July. Started at 88% with the factory-supplied battery (constant problem with Aqara) and within ten days it had dropped to 70%. It has been sitting there at 70% for three months now. I’ll update this when I have to change batteries.– The LQI shows a fairly weak connection, which is surprising given that it’s only 10-15 feet away through two interior walls. Kind of surprising given that other devices that are much further away are significantly better.The Bad:– The temperature sensors in these are utter garbage. They’re the internal temperature of the device, not the room they’re in. They’re off by 10+ degF and should NOT be relied upon in any capacity.Overall:There really are no major primary weaknesses to this device. I’ll be grabbing a couple more when they go on sale to scatter around the house. I’d like to get the Eve Water Guard but at $100 + $20/6 ft, it’s really hard to justify it.The temperature sensors are useless cost adders and Aqara would be better off just removing them.

Works great, nearly instant alarm when wet, Aqara quality
I am using 3 of these with an Aqara M3 Hub. The M3 (which I would highly recommend) has a built in speaker for alarms.Adding the leak sensor to the Hub was easy and took only seconds. The Aqara phone app offered to automatically create an alarm for them.I tested them by wetting my hand and pressing them into my hand, they each immediately notified of a leak via the M3 Hub’s audio alarm. They have two exposed metal screws on the back whihc sense water using an electrical signal between the screws. I beieve they would signal a leak if you had aproximately 1 mm of water, so not much. They do need to be placed flat on the surface you want to monitor. I put them in some corners of my basement where water has got in previously.I used these under Home Assitant as well (they work great with Zigbee2MQTT), but decided I liked the Aqara ecosystem features better. Either method of control works well, depending on your preference.Note that you compress the dome of the sensor to push the pairing “button”. And a blue LED will blink through the dome. It’s not totally obvious to do this.

Splish, Splash, and No Crash
Water mishaps in a home can be like uninvited guests at a party – they show up unexpectedly and can be a real downer. That’s where these nifty water sensors come into play. I picked up a pair, one for my heat pump water heater and the other for my washing machine. I must say, they’re like the silent, watchful guardians of my appliances.Imagine this: you’re sitting down for your favorite TV show, and suddenly your phone pings with a notification that could rival any cliffhanger – water detected! That’s what happened to me. Within seconds, I was able to avert a mini flood from my washing machine. The sensor’s responsiveness and the immediate alert to my phone were impressively efficient. It was like having a personal home guard without the need for treats or belly rubs.The setup? A breeze. Even for someone who often gets baffled by tech gadgets, I found the installation process to be straightforward. The design is compact and unobtrusive, blending in seamlessly with my home decor – a small but mighty presence.The second sensor, stationed like a silent guardian angle next to my water heater, hasn’t had its moment of glory yet, but I sleep better knowing it’s there. It’s like insurance; you hope you never need it, but you’re grateful for its existence.Sure, water sensors might not be the most thrilling topic at your next dinner party, but they’re definitely a conversation starter. “Did I ever tell you about the time I nearly had an indoor pool?” is a great icebreaker.Overall, these sensors have brought a sense of security and peace of mind to my home. They’re the unsung heroes in the world of home appliances, quietly guarding against potential disasters. No capes needed, just a reliable alert system and a little bit of tech magic.

J’ai fait l’acquisition de ce détecteur de fuite car j’en possède déjà un depuis un peu plus de 6 ans, il fait très bien son travail, placé en dessous de l’évacuation de la machine à laver où il y a parfois des débordements nous sommes tout de suite prévenus via sirène sur le hub et notifications push. Nécessite au minimum un hub aqara, la pile sur le premier est toujours celle d’origine.

Ich wollte meine Homekit basierte smarthome Landschaft um die sinnvolle Funktion „Wasserpfützen entdecken und melden“ ergänzen. Der aqara Sensor in Verbindung mit dem aqara M2 Hub ist für mich die beste Lösung. Allerdings mit Umgehung des vom Hersteller empfohlenen Installationsverfahrens 😉Meine Bedingungen waren- zuverlässige Meldung direkt in der apple home app- kein account/Cloudspeicher beim Hersteller (der icloud vertraue ich meine Daten an, den unzähligen Herstellern, die kommen und gehen nicht 🤨)- möglichst keine weitere App- kein automatischer akkustischer Signalton (Horrorszenario: bei Alarm in Abwesenheit alarmieren die Nachbarn die Feuerwehr, Türöffnung, … nein danke 🫣)Auswahlverfahren:Es gibt einen schicken Sensor von eve, der darauf ausgelegt ist, ausschließlich über homekit installiert und betrieben zu werden. Design und Konzept überzeugen, aber der Sensor hat eine interne 100db laute Sirene, die sich nicht dauerhaft stumm schalten lässt. Fällt leider weg, sonst wäre das mein Favorit geworden.Weitere Melder benötigen zwingend eine Bridge/Hub des jeweiligen Herstellers und wollen dazu zwingend eine eigene App, die wiederum ein Benutzerkonto und eine Cloudlösung des Herstellers erfordern. Will ich nicht.Die Lösung mit aqara benötigt ebenfalls eine bridge von aqara, aber die Installation ist auch direkt (!) über die apple home App möglich. Bridge und Sensoren sind bei aqara zudem sehr günstig! aqara gewinnt: aqara M2 hub (=bridge) und 3 Sensoren gekauft!Der Trick mit der Installation 😎(nicht von mir sondern von freundlichen Internetbloggern entdeckt)M2 hub am Strom anschließen, eine blecherne Stimme informiert nach einigen Sekunden, dass das Gerät im Kopplungsmodus ist. Home app öffnen und mit + Gerät hinzufügen (QR code scannen). Damit ist der M2 eingebunden.Knopf am M2 drei Mal drücken. Blechmadame informiert, dass nun Sensoren an den M2 angebunden werden können. Sensor auf stabile Unterlage stellen und 5 Sekunden auf das Symbol des Wassertropfens drücken (darunter versteckt sich ein Druckschalter). Fertig 🤗Mit dieser Lösung verzichtet man auf die vielen weiteren Möglichkeiten des M2. Der kann weit mehr als Sensordaten an apple Home weiterzuleiten, das geht dann aber wirklich nur mit der aqara App.Jetzt zum Sensor selbst:Das Teil ist winzig!!! Passt aber damit wirklich unter so ziemlich alles, was Wasser verlieren kann. Strom kommt aus einer handelsüblichen CR2032 Knopfzelle, die 2 Jahre halten soll und die einfach wechselbar ist.Der Sensor fühlt sich sehr gut verarbeitet an, sieht mit der leicht glänzenden Oberfläche gut aus und ist darüber hinaus nach IP67 wasserresistent.Der Test:macht Spaß 😄kleine Wasserpfütze produzieren, Sensor rein und keine 5 Sekunden später schlägt die home App Alarm und auch nur diese!Die Reichweite des genutzten Funkstandards Sensor – M2 Hub hat Grenzen: 1 Stockwerk und normale Zimmertür dazwischen geht, Metalltür geht nicht. Gemäß aqara soll der M2 Hub zudem nicht mehr als ca. 5m vom Router entfernt stehen, ich denke dass abhängig von Router und Repeater/Mesh-Zusammenstellung mehr geht.Mein Fazit:Zwar lässt sich das zusätzliche Zwischengerät M2 Hub nicht vermeiden, aber die so erstellte Lösung funktioniert zuverlässig, ist sehr günstig in der Anschaffung und verteilt meine Daten nicht im Netz. Und die Komponenten sehen hochwertig aus.Ich kann den Sensor und den M2 mit gutem Gewissen empfehlen ☺️
