2 Pack SNZB-02P Zigbee Temperature and Humidity Sensor, Smart Temperature Sensor with Comfort Alarm, Zigbee Hygrometer Compatible with Alexa/Google Home/HA/IFTTT, Zigbee Hub Required.

I bought the SONOFF SNZB-02P Zigbee Temperature and Humidity Sensor (2-pack) for monitoring rooms in my smart home, and they’ve been excellent. Both sensors paired instantly with my Zigbee hub and were recognised straight away no messing around, no resets, just add and go. Readings update quickly and appear accurate when compared against other thermometers and hygrometers in the house. They’re small, discreet, and easy to place on shelves or mount. Battery-powered, low profile, and ideal for bedrooms, living spaces, or server/tech areas where you want reliable environmental monitoring. I’m using them with SONOFF Zigbee devices and Home Assistant, and they integrate perfectly. Automations based on temperature and humidity work exactly as expected. Great value for money, reliable, and do exactly what they’re supposed to. Highly recommended.

Simple and do their job well. Small discrete pucks, binds directly into Home Assistant via ZBT2 no hub needed. Great for tracking room temps small and cheap enough to scatter all over the house.

Really easy to connect to my Pi with ezsp controller. I've put one in every room in the house. Reports battery level, temperature and humidity. Neat small and rugged design, like a little disk. They come with a choice of mounting options, a magnet in the back of the sensor and a metal bracket you can screw or double sided sticky to a wall or cabinet.

So plus points, easy to pair with hub, compact, great fixing it. However, variable accuracy , bought 3 of these to replace my non-networked fridge sensors. 1 out by 2c above the actual temperature. I have verified this with a thermocouple and the old sensors that agree, so 2 reference points. Same unit took about 8 hours to reach it's stable temp reading Instruction leaflet unusable, unless you use a microscope to read 😆 Only other point, the app required, limits alarm temps to those above useable freezer temps

I’ve been using these SONOFF SNZB-02P sensors for about 6 weeks (bought 4 total) to monitor multiple rooms plus my loft space and server cabinet, feeding data into Home Assistant for temperature-spike logic/automations. They paired cleanly with my Home Assistant setup via ZHA and have been reliable so far - readings update consistently and they’ve been “fit and forget”. The only minor gotcha was firmware updating: like many battery-powered Zigbee devices, you need to physically wake the sensor (press the button) to keep it awake long enough for the update to complete. That’s not really a fault with the product, just how these devices behave. Battery is still showing 100% after ~6 weeks. Overall, excellent little sensors for the money.

Great little sensors at a really good price. I’ve used SONOFF devices before and they work really well in Home Assistant, and these temperature and humidity sensors are no different. They were easy to set up using Zigbee2MQTT with Home Assistant, have been reliable so far, and do exactly what I need them to do. Overall, really happy with them and would definitely recommend them to anyone using Zigbee2MQTT and Home Assistant.

Used with home assistant to monitor room temperature and humidity seem accurate, quick to setup and connect. Also small form factor means they can easily be hidden away

Great little sensors. Super easy to set up with multiple mounting options. Perfect for use with home assistant which recognises and onboards them in seconds. They have the ability to calibrate them using a secondary proven device but were pretty much spot on straight out the box. They have been reliable providing readings for over a month now with no issues or signal drops* (*it is important to build out a reliable ZigBee mesh using bulbs/plugs etc). I will update if anything changes but initial reaction - 10/10

Ich habe einen Temperatursensor gesucht, der sich unproblematisch mit mein Home Assistant auf Raspberry integrieren lässt. Ich betreibe zwei Zigbee Netzwerke, Philips Hue zur Lampensteuerung und ein zweites über ein universal ConBee II Stick um diverse Geräte zu steuern. Der Sonoff Sensor lies sich ohne Schwierigkeiten sofort mit dem ConBee verbinden. Alle wichtigen Entitäten werden in Homassistant angezeigt und können so genutzt werden. Der Sensor hat eine sehr hohe Genauigkeit und sehr gute Reichweite. Bisher keinerlei Ausfälle. Für die Integration in HA wurde keine App gebraucht ging alles im normalen Kopplungsmodus. Das Anbringen/befestigen über eine kleine Magnetplatte ist gelungen gelöst und sehr einfach. Der Sensor ist außerdem relativ klein, gut verarbeitet und fällt nach Installation kaum auf. Von mir fünf Sterne, da sich der Sensor auch ohne einen Sonoff Hub aufgezwungen zu bekommen sofort mit meinem ConBee pairen ließ. Das ist heute nicht selbstverständlich. Von mir klare Empfehlung vor allem in der Anwendung mit Home Assistant.

La qualité ou les fonctionnalités sont très variables d'une marque à l'autre. Celui-ci est le meilleur de ceux que j'ai testé (sous Zigbee2MQTT): 1. inertie assez faible. 2. Mesure au 0,1° 3. possibilité de modifier la fréquence des rapports vers la centrale. 4. Possibilité de calibration. 5. Mesure de la batterie restante en % NB: la version avec écran est un peu moins performante : inertie plus grande et mesure en 0,2°. Le reste est identique.

Worked straight in with Ikea diregera smart hub.

He adquirido este pack de dos sensores de temperatura y humedad SNZB-02P para monitorizar las dos estancias clave de mi casa: el baño y el dormitorio principal, y la experiencia tras integrarlos en mi sistema domótico ha sido impecable. El acabado circular es mucho más estético y moderno que el modelo anterior. Además, la base magnética y el adhesivo 3M facilitan mucho su colocación en cualquier rincón sin que desentone. Los he emparejado mediante Zigbee2MQTT (también funcionan perfecto con ZHA) y la integración es nativa. Te reporta temperatura, humedad y el nivel de batería de forma muy estable. Al ser Zigbee 3.0, no saturan mi red Wi-Fi y actúan de forma local y privada. Si usas Home Assistant, no busques más. Por este precio, tener dos sensores con tecnología Zigbee 3.0, buena autonomía de batería y una tasa de refresco tan fiable es una compra maestra. Ideales tanto para confort climático como para prevenir humedades.

Perfetti, affidabili e facili da configurare.
