Temperature and Humidity Sensor, REQUIRES AQARA HUB, Zigbee, for Remote Monitoring and Home Automation, Wireless Thermometer Hygrometer, Compatible with Apple HomeKit, Alexa, Works with IFTTT

I used to use Sonoff products for my home automations in Home Assistant, and I still use their Zigbee hub, but unfortunately the reliability of sensor connection was very poor. I had to restart it at least once every one or two weeks. Obviously, there's no automations to be had if you can't rely on your sensors being available. The battery life was also quite poor for Sonoff products. So I've started looking for something I can rely on. I knew about Aqara, but their products always looked so much pricier than Sonoff. But I had to try something or give up on home automations in my house altogether. So I've got myself a temperature and a motion sensor from Aqara. Connected them and waited for at least half a year to see how it fares. I can't remember having any signal loss in that time! I then got a couple more sensors and moved them to most inaccessible places such as attic. Had maybe 1 or 2 signal losses in 2 or more years! On top of that, the battery life is amazing! I think I only need to change the battery once in 2 years. I'm do to get my last 3 sensors from Aqara and because of their reliability I will be finally able to create some automations I can rely on. Speaking about the downsides of Aqara - besides the price, I find that the battery cover is made of very soft plastic and the groove meant for opening it simply brushes away trying to change the battery. For that reason you may find that your sensor may not last more than 2 battery changes unless you glue something extra on it. For something this expensive I think Aqara should come up with some more user friendly ways of changing batteries of their products.

Have one of these in my freezer after an incident where the door didn't close properly. Works with Home Assistant using a SonOff Zigbee usb stick and no issues. Working down to -18c as shown in the images. Reported battery dropped like a stone (probably due to temperature) but it's been in the freezer since 1st August 2025 and hasn't moved significantly since. As long as it reports I'm happy. Simple to set up. No need for the Aqara hub if you have a 3rd party zigbee dongle.

I now have eight of these temperature and humidity sensors scattered around our house, they were simple to set up along with the M2 hub and integrated easily onto my home assistant. They appear to be accurate and responsive to change in temperature so very pleased with them. The only negative is the battery which is included in each sensor is either very poor quality or old because they only lasted for two weeks! I have replaced 3 of them with Duracell batteries and so far so good.

IT is simple to set up and easy to set up.

Nice and small so easy to hide out the way. Seems to be fairly accurate. Delivered on time would recommend.

Works really well and the double sided tape is perfect, very strong. I don’t know how accurate the sensitivity is, but integrates well with aqara and HomeKit. I had issues with one room being damp, so this allows me to keep an eye on the humidity level when running the dehumidifier. Battery has been holding well for the last 6 months, it does go down quite quickly to begin with, then settles. It is a bit in the expensive side, but honestly all the aqara gadgets we have are well built and I know it will last long.

I've purchased two of these last week and their battery life has dropped faster than Eddie the Eagle (yeah I'm that old :). One is showing 44% battery and the other 56% and both dropping about 4% every few hours (as per Home Assistants graph). So I guess I might get two weeks out of a battery and not the two years advertised. On a positive note they look smart, are compact and their readings are the most accurate of all my zigbee devices. They also have a pressure sensor which is not often mentioned. However, two weeks battery life...

Another Aqara product for my home. These are a great little sensor and always work and never let me down.

Once the m3 hub was installed. The temp and humidity sensors were a breeze to setup. Using in three rooms and have been more reliable and accurate than HomePod mini’s built in sensors.

Czujnik NIBY do wewnątrz ALE stosuje go na zewnątrz. Bateria jest bardzo dobra. Odczyty bardzo dobre. Polecam

klein preisDer Aqara Temperatursensor ist wirklich super kompakt und fällt im Raum kaum auf. Die Einbindung über Zigbee lief absolut schnell und problemlos.

Ho avuto l'opportunità di testare l'Aqara Sensore di Temperatura e sono rimasto molto soddisfatto delle sue prestazioni e della sua affidabilità. Questo piccolo dispositivo ha dimostrato di essere un'aggiunta essenziale alla mia casa intelligente, fornendomi informazioni precise sulla temperatura dell'ambiente. La cosa che mi ha colpito immediatamente è stata la facilità d'installazione. Basta posizionare il sensore nella stanza desiderata, utilizzando l'adesivo incluso o un supporto magnetico opzionale, e connetterlo alla mia rete Zigbee tramite il gateway Aqara. La connessione è stata stabile e senza problemi, consentendomi di monitorare la temperatura in tempo reale attraverso l'app Aqara sul mio smartphone. La precisione delle letture di temperatura è stata impressionante. Ho confrontato i dati forniti dall'Aqara Sensore di Temperatura con altri termometri affidabili e ho riscontrato solo minime differenze, confermando l'alta precisione del dispositivo. È in grado di rilevare anche variazioni di temperatura minime, il che è particolarmente utile per garantire un comfort ottimale in casa. Una delle caratteristiche che ho apprezzato di più è la possibilità di impostare notifiche personalizzate. Tramite l'app Aqara, ho potuto stabilire dei limiti di temperatura e ricevere avvisi direttamente sul mio smartphone quando la temperatura raggiungeva valori critici. Questo mi ha aiutato a mantenere un controllo costante sulla climatizzazione della mia casa e ad adottare le misure necessarie per mantenerla confortevole. Un altro aspetto positivo dell'Aqara Sensore di Temperatura è la sua compatibilità con altri dispositivi smart. Grazie all'integrazione con la mia piattaforma domotica, ho potuto automatizzare diverse azioni in base alle letture di temperatura. Ad esempio, ho creato una regola per attivare il mio sistema di riscaldamento o di raffrescamento quando la temperatura arriva ad un determinato valore. Nel mio caso ho utilizzato l'hub personale HOMEY PRO. Da un punto di vista estetico, il sensore ha un design pulito e discreto, che si adatta facilmente a qualsiasi ambiente. La sua batteria a lunga durata è un altro vantaggio, poiché non devo preoccuparmi di sostituirla frequentemente. In conclusione, l'Aqara Sensore di Temperatura si è rivelato un dispositivo affidabile, preciso e altamente funzionale per il monitoraggio delle temperature in casa. Con la sua facilità d'installazione, la connettività stabile e la possibilità di personalizzare notifiche e automazioni, rappresenta un'aggiunta di valore al mio sistema smart home. Consiglio vivamente questo sensore a chiunque desideri tenere sotto controllo la temperatura dell'ambiente in modo pratico ed EFFICIENTE senza spendere troppo

I wanted to know the temperature and humidity on our lanai. I already had some Aqara devices so this seemed like the perfect fit. Super easy to connect. I have a big thermometer out on the lanai already. It seems to display the same temperature. So I’d say it probably more accurate than my thermometer. It is pretty far from the hub, plus it has to go through cinder block walls and it works with no issues. It’s nice and small. To be honest, I forgot where I put it out there. I’m going to have to find it eventually. I would purchase this again without a doubt.
