You need them! Buy them before the leak or you will after!
Yes, this is one of the devices that most people don't prioritize having or just start to discover their existence after a leak happened. Well, I've learned it the hard way after a pipe burst in attic and there was water damage all the way to the ground floor. And funny point is that in life we all pay sometimes a ridiculous amount of insurances, some compulsory, some by choice but often useless. These flood sensors are your kind of equivalent of insurance or better said prevention from consequences of a heavy flood, just long term and relatively cheap. And if we consider what major leaks can cost - then super cheap. Let me quickly summarize the key points so far: 1. Works and works fast. Either leaks or drips, once the liquid touches the sensor you will know instantly. Just make sure you are positioning it correctly and if possible in such places so you avoid false alarms. What do I mean? Well I've placed one of mines in the bathroom corner, close to the toilet. One of the evenings we all simply jumped up of the loudness of the alarm, which was due to my sons poor aiming in the toilet. I'm under impression that loudness and unexpected scream scared him so much that it made the aiming situation even worse haha. By the way don't worry, you can change the alarm volume and duration and this is exactly what I did after this case. 2. Decent app and good notifications. Well, this one is as important as the device itself, because if leaks happen when you're not home - you want to know about this fast and be able to act fast too. Actually, it's important when you're at home too. Beside reminders and emails - the phone pop-ups are very informative and useful. Just make sure you allow them! Setup was quick and straightforward, there is no rocket science behind it. I've tested it so far with Alexa and it works. I expect it to work with other claimed services from Google and Siri, but I'd personally won't rely on this as number one interaction or communications channel. I hope for my Alexa just to notify me when batteries are low - this will be super helpful, as obviously you want these sensor to be on and running and not dead if a leak happens. Connectivity throughout the house for me is also good, but make sure to test it if you live in castles or spread multiple sensors in separately standing granny flats, garages, etc. Don't just trust the claimed 120 meters as it will depend a lot on build materials, interference, etc. To summarise: This is a device that you hope that you will never need, but trust me you want it to be in your house just in case, for peace of your mind, because if a leak happens, you will thank yourself a lot. And if you knew about such sensors and did not buy one - it will be bitter! Anyway, hope my 5 cents help a bit. Stay well and dry haha! Cheers!

Totalmente funcional y muy recomendable
Tras varios meses de uso he de indicar mi total satisfacción con el producto. Compré un pack de tres tras haber probado el producto individualmente. Los tengo distribuidos por la cocina, baños y lavadero, de tal forma que me permite detectar cualquier fuga de agua antes de que provoque un problema grave. Especial mención cebo hacer del sensor que coloque junto a la toma de agua de la nevera americana, gracias a lo que me di cuenta de una ligera perdida en el conducto plástico, que de haberse rodo habrÃa provocado un escape grande. Indicar que además del pitido que emite el propio sensor, los tengo vinculados con mi aplicación Alexa, que me permite recibir una aviso de alarma a través los altavoces , además de la notificación al móvil que tengo configurado en la propia app de Switchbot. Por todo ello debo indicar que el producto es totalmente recomendable.

Affidabile, completo e facilissimo da configurare – Super consigliato!
Desideravo acquistare un rilevatore di perdite d’acqua e ho colto l’occasione del Black Friday per prendere questa confezione da 3. Sono rimasto davvero soddisfatto: SwitchBot conferma ancora una volta la sua qualità . Qualità costruttiva eccellente I rilevatori sono leggermente più grandi di quanto immaginassi, ma la dimensione è perfettamente adeguata alle funzioni e non crea alcun problema nell’installazione. La struttura è solida e lo scomparto batterie è completamente ermetico, così da evitare infiltrazioni d’acqua. Confezione completa Nella confezione ho trovato: - 3 rilevatori - 3 set da 2 batterie AAA già pronte all’uso - Un pratico utensile rigido per aprire lo scomparto batterie Un kit davvero completo, pronto da installare in pochi minuti. Doppio sensore molto preciso Ogni rilevatore integra: - Sensori superiori per rilevare gocciolamenti - Sensori inferiori per rilevare acqua a terra La sensibilità è ottima e la risposta immediata. Notifiche intelligenti e allarmi indipendenti Una delle funzioni che ho apprezzato di più è la flessibilità nella connessione: - Si collega all’hub SwitchBot se presente - Oppure direttamente al Wi-Fi, senza bisogno di hub In caso di perdita invia: - Notifiche sull’app - emette un suono a 110 db - Email fino a 10 indirizzi contemporaneamente Una sicurezza in più, soprattutto se si è fuori casa. Configurazione semplicissima L’associazione all’app è stata immediata e senza intoppi. Tutto molto intuitivo, come da tradizione SwitchBot. Batterie longeve La durata dichiarata è di circa 2 anni, un ottimo valore per un dispositivo che deve funzionare in continuo. Conclusione Prodotto eccellente, affidabile e completo. SwitchBot continua a offrire soluzioni smart di qualità superiore. Rapporto qualità -prezzo ottimo. Assolutamente consigliato!
