I've bough about 10 Need them to keep 2 online

More than frustrated. Bought the ZB model and they will not stay online. Also bought some of the button switches. The too drop offline. Pain in the butt.

The only Sonoff sensor that works every time is the RF Motion Sensor. Works all the time. Wow.


Well, I'd like to leave a good review but this is the first device from Sonoff I honestly can't. I bought 8 of them all at once since all the minir2,19 of them, and the basics,3, worked fine. The problem is I never know which one will actually work. On the first day, every one of them connected and set up fine. Today less than a month later one doesn't work at all, I suspect a bad battery and the rest are not reliable. I have ordered some new batteries even though they read fine in the ewelink app. I'm using with the sonoff zigbee hub.
I suggest buying several from different companies and doing a longer test with them and buying the most reliable after some time, maybe 6 months to a year.

Sorry for the inconvenience, our customer service will contact you to help you solve this issue.

Great product and fast delivery from ITEAD

Sonoff products are reliable, effective and get the job done. Very glad ITEAD carried them and was able to deliver them very quickly - saved a lot compared to buying it from Amazon.

Ugly but worth every cent

It is an ugly looking sensor, but despite its looks one of the best on the market. I have been using the Sonoff products for many years and have installed hundreds of their units. Their Zigbee products are great, easy to set up and are a breeze to integrate with Home Assistant. Over time they have proven to be reliable and value for money. The choice to go for larger batteries and that offer a longer installation life makes maintenance a pleasure. Of course, because it reports the battery life, you can easily setup routines to pre-advise you about the need for battery replacement. They did a great job with the ZigBee motion sensor.
