SONOFF SNZB-03P Zigbee Motion Sensor 1-Pack, 3-Year Battery Life, for Alert System and Automations Wireless Motion Detector, SONOFF Zigbee Bridge Required, Batteries Included

I have been using them for a year now and they have never failed me. Just occasional hubernations to save energy when not in use for extended periods. But they usually spring back to life as soon as motion or presence is detected

I ordered these Sonoff Sensors to implement into my home assistant setup. The sensors were immediately recognised by the sonoff zigbee 3.0 plus dongle and added to my HA setup. The sensors work great with Alarmo. The sensors were much smaller than I anticipated. They work very well and the sensitivity is high, so much so that my robot vacuum cleaner set these off in the middle of the night. They are also not pet friendly, my dogs were easily detected by each of these sensors. I have had to angle these up towards the ceiling in order that they do not catch the floor area, thus moving them out of the range of my dogs and vacuum. Even though they are pointed upwards they do still detect a human presence which is great, the issue is the range is just not as good now. The sensors can be attached by magnet to a metal base or by the included 3m sticker, or with plain old wall screws. In summary for a home without pets or robots these would work great, either as an alarm sensor or as a PIR for lighting ect. ZHA does not allow the changing of the cooldown time, so you are stuck with 60 seconds. There is a workaround available however this did not work for me, and no matter how much i tried to reprogramme the cooldown time in ZHA the controller failed to write the new parameters. One other thing of note is that the motion sensor sensor in ZHA is always 'detected' so you can not use this, however the 2nd entity exposed is occupancy, this is what you use when implementing to ZHA. I hope you found this review helpful

Brilliant for the bathroom to trigger my Aurora lights on HA automations - works perfectly, have also set up a "bypass" so I can keep the lights on longer than 2 minutes if having a bath / extended bathroom visit. Cant complain at all, superb.

Great motion sensor, easy to setup using the eWeLink app and a Zigbee hub. Comes complete with screws and self adhesive mounting, you choose your preferred method. The magnetic sensor to base mounting makes it easy to position or to access the battery. I found it difficult to access the battery compartment (old hands), it is tight to turn - but easier once I realised you turn slightly and then pull 🤦‍♂️ Great little sensor - I have two of them and like the Sonoff products generally.

Using these motion sensors with Home Assistant. Work very well. Using them for human presence detection.

Works with Alexa, but couldn't get it to work with home assistant.

Great for motion activated lights in hallways, kitchens etc. But not ideal for bedrooms as it cannot detect a still person. So it should only be used in rooms where you're not going to be sitting down, as if youre still for more than 60 seconds it will not know you're still in the room. Still very easy to intergrate into home assistant. It doesn't turn lights off after leaving a room as fast as a mmwave sensor as it needs the longer 60 second cool down to be effective, but perfectly usable. I'd like it if I could control the cool down manually.

Integrated one of these with home assistant (since I already had other zigbee devices, I already had a hub connected to it). I really like that it connects to the base magnetically, that makes it easier for when you have to change the battery. The detection works nicely, and once it was paired with the hub that home-assistant was using, integrating the sensor with the lights I wanted it to control was a snap.

Took less than 5 minutes to setup on my Zigbee with Home Assistant and Z2MQTT. I setup the SNZB-03P motion sensor on my freezer in the garage and now I control my light whenever I get near it. I have no issues and appears to work each time. A simple, smart, and great product. CON: The sensor is magnetically attached to it mount so it can be knocked off or moved out of position if place in a reachable location. Now we'll see how long the battery will truly last.

This is a great, responsive motion sensor that also has an ambient light sensor built in (though not in the best implementation). This makes it perfect for use in automations where you want a light to turn on, only when a specified darkness level is reached. I was able to pair this up and incorporate it into my Home Assistant setup via zigbee2mqtt with no issues. It has performed exactly as expected and I've had no issues with the motion sensing. The ambient light sensor is nice to have (my previous motion sensors did not have one), but unfortunately the device only seems to report either "dim", or "bright". It would be much more preferable to have a numerical value reported so that you can customize your automations with more flexibility (e.g. the reported "dim" value might not be as dim as I would like). While better than not having a sensor at all, it's still a disappointing implementation.

Ils sont faciles à installer avec Home Assistant, et configurables. Ils font parfaitement leur travail, mieux que ceux de Hue je trouve. À noter que ça ne remplacera jamais un détecteur de présence, mais ceux-ci sont parfaits pour les couloirs, escaliers, ou pièces où l'on est en mouvement comme une cuisine.

Works very good 👍

Dopo aver utilizzato il SONOFF SNZB-03P, sono pronto a condividere la mia esperienza con questo sensore di movimento ZigBee, un prodotto che si integra facilmente nel mondo della domotica. 🔹 Pregi: 1. Rilevamento Veloce e Affidabile: Il sensore è in grado di rilevare i movimenti in meno di 5 secondi, garantendo un'alta reattività nelle automazioni. Ho testato questo aspetto con successo in scenari diversi, come l'attivazione delle luci al mio passaggio. 2. Compatibilità con Ecosistemi Domotici: Grazie al supporto per Alexa, Google Home e Home Assistant, l'integrazione con i principali assistenti vocali e piattaforme domotiche è fluida e semplice. Una volta configurato, il sensore risponde perfettamente agli ordini vocali e alle automazioni, rendendo l'esperienza utente senza soluzione di continuità. 3. Design e Facilità di Installazione: Il dispositivo è compatto e discreto, perfetto per essere posizionato in vari angoli senza impattare sull’estetica dell’ambiente. L'installazione è rapida, con batterie incluse, e non è necessario l'intervento di un esperto per avviare il sensore. 4. Ecosistema ZigBee: Il supporto per ZigBee 3.0 consente un'integrazione robusta con altri dispositivi compatibili, rendendolo un'ottima scelta per chi ha già un impianto domotico basato su ZigBee. 🔻 Difetti: 1. Richiesta del SONOFF Zigbee Bridge: Per utilizzare il sensore, è necessario possedere il SONOFF Zigbee Bridge, che non è incluso nel pacchetto. Questo può essere un ostacolo per chi non ha già investito in un bridge ZigBee. 2. Portata Limitata: Sebbene il sensore funzioni correttamente in ambienti non troppo grandi, la portata potrebbe risultare limitata in spazi molto ampi. È importante fare attenzione alla posizione in cui si installa per garantire una copertura adeguata. 3. Integrazione con Pochi Sistemi: Sebbene funzioni bene con Alexa, Google Home e Home Assistant, potrebbe non essere altrettanto compatibile con tutti i sistemi domotici sul mercato, limitando un po’ la versatilità per gli utenti che utilizzano altre piattaforme. 🔧 Collegamento a Home Assistant: Per integrare il SONOFF SNZB-03P con Home Assistant, è necessario un ZigBee Gateway, come il SONOFF Zigbee Bridge, o un altro coordinatore ZigBee compatibile con Home Assistant (ad esempio, il ConBee II o l’Zigbee2MQTT). Una volta configurato il coordinatore, puoi aggiungere il sensore tramite l'interfaccia di Home Assistant. La procedura prevede: 1. Aggiungere il coordinatore ZigBee in Home Assistant. 2. Avviare la modalità di accoppiamento sul sensore SONOFF. 3. Aggiungere il dispositivo ZigBee rilevato in Home Assistant per configurarlo nelle tue automazioni. 🔚 Conclusioni: Il SONOFF SNZB-03P è un sensore di movimento affidabile e reattivo, ideale per chi cerca di integrare la domotica in modo semplice ed efficace. Se già possiedi un ecosistema ZigBee, o sei disposto ad acquistare il bridge necessario, rappresenta una scelta molto valida per automatizzare la tua casa. La compatibilità con Home Assistant amplia ulteriormente le opzioni di automazione, permettendo di sfruttare appieno il potenziale del sensore. I punti deboli sono minori e facilmente risolvibili, facendo di questo sensore un prodotto consigliato per gli appassionati di smart home.
