SONOFF 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.

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.

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

Initially very poor connectivity on a couple of sensors ( a temperature sensor and a door opened sensor), with one needing regular restarts. After a lot of fiddling with repeaters in the same room as the sensors, the temperature sensor is working fine with no drop outs. However whatever I try, the door opened sensor still regularly drops out for an hour or so, and then reconnects. At least it does not need restarting. Now all my 6 temperature sensors are working flawlessly, after very attentive support from the seller, I am upping my review to 4 stars. I guess batery powered zigbee devices are very sensitive to the zigbee signal and this may not just be a Sonoff issue.

These are really good sensors, I have 6 of them currently. The easily bind to a sonoff dongle running zha and connected to home assistant. They never seem to drop out and have a pretty good signal range, I have one in my greenhouse in the garden and it's picked up through the zigbee mesh easily. I do have lots of mains powered zigbee devices that act as routers, so probably have good coverage. On that note being battery powered they are endpoint devices. I have been running some of these for about a year so the battery life is at least that good, but they are still showing 100%, so we will see how that goes. Mounting is easy, being magnetic they can stick to anything metal or you can stick or screw the small metal plate that comes with them up and mount them that way. Happy with them so far.

Work exactly as described and connected to Home Assistant first time. I have a mixture of these and the ones with the display and all give consistent accurate readings.

Running with a Sonoff Zigbee dongle. These devices apparently have 3 modes of operation: Not updating temperature or humidity regardless of changes in environment; updating humidity at 5 min intervals (but not temperature); unavailable. They pair readily enough, but thereafter will probably do nothing. Resetting them doesn't work, nor does removing the battery for a while. This isn't range. They're right beside the dongle for testing. This isn't compatibility (unless Sonoff has managed to produce Zigbee devices that are incompatible with each other). This isn't battery. They're fundamentally unreliable to the point of unusable. It's difficult to assess accuracy when the fundamental communication isn't happening. This is - apparently - well known as an issue with these. I've bought some competing devices and have no problem with them. I would strongly recommend avoiding these.

Sime and easy to use sensors that can be placed pretty much anywhere. I use them with Home Assistant's Zigbee integration and it works really well. I also have a SONOFF smart plug which acts as a Zigbee router to enable the sensorts to be placed quite along way from the Home Assistant server.

These are great at what they do, packing a lot of functionality into a nice small form factor. They connect easily to home assistant (via zigbee2mqtt) and give accurate readings. We’re using them to monitor the temp and humidity in our cellar and find them really helpful for working out what we need to do with heating/ventilation to keep the rooms damp free. Great value for money - would definitely buy more of these

Avec l'app Smartlife (+hub loratap) la connexion était instable et je n'ai jamais pu l'utiliser correctement. Depuis que j'ai Home Assistant, le capteur est parfaitement reconnu et utilisable notamment pour des automatisations de ventilation en fonction de l'humidité. Depuis un an la pile n'a pas encore dû être changée.

I bought 4 of these. Three of them work great, but one cannot keep its connection. It doesn't matter where I place it, it's just unreliable.

Sensori facili da abbinare e con una rilevazione precisa

Die Temperatur- und Feuchtigkeitssensoren machen einen hochwertigen Eindruck. Verarbeitung und Haptik sind deutlich besser als bei vielen vergleichbaren Modellen. Die magnetische Befestigung ist praktisch, und die kleine Wandhalterung zum Aufkleben ist gut durchdacht. Die Einbindung in Home Assistant funktioniert ohne Aufwand. Insgesamt ein zuverlässiges Set, mit dem ich sehr zufrieden bin.

Worked straight in with Ikea diregera smart hub.
