Ho acquistato il rilevatore di perdite d’acqua SwitchBot a gennaio 2025 per installarlo vicino alla caldaia, così da prevenire eventuali perdite o gocciolamenti. Dopo diversi mesi di utilizzo si è dimostrato un prodotto affidabile e molto utile. L’installazione è semplicissima: si configura in pochi minuti tramite l’app SwitchBot, senza bisogno di hub, e può essere posizionato facilmente anche in spazi ristretti. Il sensore rileva immediatamente la presenza di acqua e invia notifiche istantanee sullo smartphone, oltre ad attivare un allarme sonoro ben udibile. Ottima anche l’affidabilità nel tempo: nessun falso allarme e batteria ancora in ottime condizioni. Per chi ha una caldaia in casa o in un locale tecnico, è una soluzione pratica ed efficace per aumentare la sicurezza e prevenire danni. Rapporto qualità-prezzo eccellente. Consigliato senza dubbi.

This is a great little piece of kit that has helped me whilst away. It actually activated whilst I was travelling so I could send somebody around to have a look. Turned out to be a false alarm but thankful for it letting me know rather than coming home to a water leak. It’s easy to use and set up. The iPhone app is straightforward and uses notification alerts. I’ve had this for a few months and the battery seems to be OK. I have recommended this sensor to others and will be buying more in the future. A quick, easy, and cost effective way to protect yourself and your home!

"installé" ( juste posé) dans ma cave sous la tuyauterie de la maison.. il m'a déjà sauvé une fois de gros dégâts en m'alertant pendant que j'étais au travail d'une fuite d'eau d'un raccord qu'il a capté de part le premier niveau du capteur ( humidité) (au delà de qq mm l'autre capteur un peu plus haut alerte aussi de fuite plus importante ) j'ai crée une automatisation pour une alerte claire qui est relayée par wifi. j'ai fait aussi un essais sur place avec l'alarme qui en position forte réveille bien... enfin je "l'emprunte" parfois lorsque je pompe les cuves l'été pour être averti quand plein ( déborde) . très pratique !

観賞魚水槽でインラインヒーターやCO2ユニットを使っており万一に備えて深めのトレイを敷いているがトラブルがあった際に携帯へすぐにアラートが飛んできてほしいので設置しました。また、半地下潜った場所にあるピットで冠水した際の警報としても使えるように追加設置しました。感度良好で良い製品です。
