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.

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.

I've had several of these set up for a couple of years now, still running strong on the original batteries even with the increased reporting interval I configured. They paired without issue and produce reliable and accurate temperature readings. The humidity readings are also good, much improved, resolving the issues with Sonoff's original square sensors. Another big improvement is the magnetic mount, which will make changing the batteries much easier when they eventually run out. This would be a 5-star item if it wasn't for one thing: the magnetic metal mount plate really should be more discreet. I'm sure sonoff loves how it fits with their orange brand, but it's not what I really want when the sensor should be as invisble as possible.

The latest protocol zigbee temperature and humity sensors from Sonoff work very well and offer better connectivity and battery performance than their predecessors, which these have replaced. I have two of these in freezers, and another two in fridges as the older versions lost connection in the cold after a while - the older ones are fine for other uses! Mine are connected to my Hubitat hub and report every 0.25 degrees Celcius change. I have the humidity function turned off.

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

Working fine, results are reliable and consistent.

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.

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.

Använder dessa överallt i huset från vind till utomhus och har fungerat perfekt

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.

Hatte bisher immer die Sensoren von Aqara verwendet. Jetzt einmal diese hier probiert. Was soll ich sagen .... absolut genial! Nicht mehr direkt auf Möbel oder Wände kleben, sondern einfach mit dem integrierten Magnet befestigen. Wenn irgendwo kein Metall zum anbringen ist, einfach die beiliegende Grundplatte ankleben und das Gerät darauf magnetisch fixieren. Die Anbindung in Home Assistant ist absolut problemlos und ich hatte bisher noch keinen einzigen Ausfall. Auch ist die Genauigkeit der Messungen vergleichbar mit allen anderen Sensoren die ich in Betrieb habe. Volle Empfehlung!!!
