SONOFF Zigbee Indoor Temperature Humidity Sensor, SNZB-02D LCD Zigbee Thermometer Hygrometer, Works with Alexa & Google Home for Remote Monitoring and Home Automation, ZigBee 3.0 Hub Required, 1-Pack

The SONOFF Zigbee Indoor Temperature Humidity Sensor (SNZB-02D) is an excellent, versatile device with reliable performance. Despite being marketed as an indoor sensor, I installed it outdoors, and it has held up well. It integrates seamlessly with Hubitat, making it an ideal choice for smart home enthusiasts. In my setup, I use it to monitor outdoor temperatures to automate switching between my heat pump and oil heating system. The sensor provides accurate and consistent readings, enabling efficient control of my heating system based on temperature thresholds. Overall, this sensor is a great value, offering flexibility and reliability for various use cases.

Worked perfectly with my Samsung Smarthings! Connected to Smarthings, created a routine to turn on a smart plug for my garage heater, and it worked effortlessly. Now, it turns it on and off per my temperature requirements. Couldn’t get Alexa with the built in temperature sensor to do this consistently. But this thing works great!

The most important thing to me was how easy it is to hook up to SmartThings. I got this because someone on forums had recommended it because it is a Zigbee protocol device. Most time Zigbee devices can just be scanned for within SmartThings and you don't need to download any other special app. That was the case here although it was a bit of a puzzle on how to initiate pairing. It didn't actually say how in the little user booklet that has absolutely tiny writing in it in many languages. I had to find the manual online. It's such a simple thing why don't they just put that in large letters right in the front of the manual. All you really need to know on this thing is that you pull off the film so that the battery inside engages, then press the tiny little button on the back for about 5 seconds until the little broadcast icon starts flashing on the display. Then initiate a scan in SmartThings and it should pair pretty quickly and start showing the temperature and humidity within SmartThings. The other use of the button which is also not in the manual is that if you click it once it will change from C to F. Again basic basic stuff and it's not in the stupid little booklet they send, which really only tells you to go download their app which you don't really need. So that's why I'm deducting one star. I like the fact that this has a clear LCD display that's always on. A lot of these little units are just blank white plastic boxes. Accuracy is okay. It reads maybe 1° higher than my trusty mercury thermometer. I think it's more accurate than the little black thermometer unit shown in the photo. In SmartThings it responds perfectly and you can use it as a condition for actions. You can also see a nice graph of the temperature over hours and days. Nice. So what I really wanted to do with this was put it in my living room and have it turn on the air conditioning which is on a smart plug, during a certain portion of the afternoon, only if the temperature gets above for example 77F. My AC unit is perfectly safe to use turning it on and off with the main supply power. So: create a new SmartThings routine, as an IF precondition, set this sensor as equal to or greater than 77F. Then set the second IF main condition as a time range say 1pm to 6pm. THEN: turn on AC smart switch. If it never reaches 77F the AC won't come on. If it doesn't reach 77 until 3:30pm, it will only come on at that point. It works well, very very simple but effective. One could also set it to turn off in an evening time range as well if it reaches a certain temperature. But I have not needed to do that yet here in summer, since I always turn it off at sundown regardless and open the windows. This AC has a heat pump so I plan to use it in the winter too with a low limit temperature using the sensor. So this is maybe not as fancy as using something like a nest thermostat, but on the other hand it's very versatile, simple, cheap, and I can just use Smartthings alone, but also still turn it on and off with a Google home command.

Received my temp sensor last night. It works as intended. However, it was either preused or it sat on a shelf for a very, very long time. I removed the plastic tab that keeps the battery disconnected until purchase and the battery is almost dead. The screen randomly dims (its not backlit) so i assume a poor connection internally.

Lovely display, very clear with light. This doesn't have a backlight so no night reading. The reporting to the zigbee network is timely. I would love that the display also had a clock. It is the only thing that I miss on this device.

Item works in Celsius mode only. Instructions direct you to scan the QR code, however, QR code shows to be invalid.

My roommate is always worried about the temperature in the basement. He's afraid that the pipes are going to freeze some day. I bought this sensor to appease him. I set up a routine in SmartThings that sends me an alert if the temperature drops below 37. It's never even come close. I like that this sensor has a display, most don't. It also measures humidity, which not all sensors do; this is particularly useful in a basement.

Impeccable. Fait le taff, bonne taille et facile à intégrer. Je vais en commander plusieurs, c'est sûr.

Descripción del producto para su venta dice: 2 paquetes y solo viene 1. Pero si es buen producto

Jag gillar verkligen de här. Stor och tydlig display. Bra batteri cr 2450 som håller betydligt längre än cr3230.

Çok küçük, şık ve kaliteli hissettiren bir sensör. OEM Zigbee usb hub ile sorunsuz eşleştirdim. Kablosuz mesafesi oldukça iyi, arada 2-3 oda olmasına rağmen kesintisiz bağlanıyor. Tavsiye ederim.
