SONOFF SNZB-02P ZigBee 3.0 slimme temperatuur- en vochtigheidssensor, voor bewaking op afstand en domotica, ZigBee Hub vereist, compatibel met Alexa/Google Home/Smartthings

Easy to use sensors, but it of course requires a Zigbee gateway. It was very easy to pair with the Sonoff Zigbee dongle through Home Assistant.

I've tried MANY temperature sensors, and this one is my favorite. Because it's a Zigbee device, and not Wi-Fi, connectivity is reliable and has great range. It pairs instantly with Alexa devices that have a built in Zigbee hub. Alexa devices with Zigbee include:Echo 4th generationEcho PlusEcho Show 10 (all models except 1st generation)Other than the Alexa app, you do not need any app to support this device, but setup in Alexa is cumbersome if you're not familiar with it. To complete the setup in Alexa (Screen shots shown in images),1) Open Alexa and select "More"2) Select "Routines"3) Select "Home Automation"4) In Home Automation, select the plus sign (+) to add a routine.5) Build a routine to alert when cold6) Build a routine to alert when hotThe packaged app (eWelink) is lousy, borderline useless, but you can use Alexa or Google instead. The temperature is accurate, mounting hardware is both magnetic and adhesive, battery life (4 years) is unmatched, pairing is simple and reliable, connectivity range is great, and overall hardware quality is fantastic.Great for kennels, coops, freezers, or any area.

Uso questo sensore di temperatura da un po' di tempo in abbinamento con home assistant e devo dire che funziona molto bene e preciso e la batteria dura molto mi sento di consigliarlo

By far the best you can get, and very accurate and reliable temp measurements with 0.1-0.3 accuracy and pretty impressive RH measurements. Putting a bunch of sensors together gives a very consistent testresult. I have them all over the place after pairing and checkup, and some of them are like 15-20m from the last Zigbee router (read lamp) and no problem with connections.Very good brand, use Sonoff for many years without any problems. Everything works and keeps working. Build quality also pretty good. This by the way does not count for all of their products, like the new PIR detector. But the temp/RH sensor is stunning.
