Zenitech Beewi BBW200 Smart Temperature & Humidity Sensor

First unit was broken and the second unit got so hot that I could not hold it in my hand for more that 2-3 sec. Worst crap I ever bought.

Quite neat. Palm sized unit. Takes 2x AAA batteries. It has a faint blue glow when actively paired. This unit will record temp and humidty every two hours, ongoing. I don't think it tells you what it happening right now, just the last recorded data. When you connect via the app it syncs all history to the app to display. I bought it to monitor an inaccessible sub-floor void for temp and humidty, which it is perfect for. It got chucked-in through an airbrick, probably never to return. I can connect from within the room above the suspended floor.Only criticism would be that the screws to open battery compartment are very very small and will require a precision screwdriver to access.

The item itself is fine. Well made and light, but a little bulkier than expected.Pairing is easy enough (Android) but that is where the praise ends.The app itself is horrible, and doesn't offer many functions or settings to fine tune how this device is used.It only logs data on the hour, so don't expect regular updates for accurate temperature keeping.As for viewing the data, that is another dreadful experience. Despite only having one sensor visible in the app, you have to select it in order to view the info, and it fails to connect and load the info far too often.I put a video on YouTube showing it failing to connect despite being sat right next to the device, and if the sensor is across the room (2-3 metres away) it fails to connect at all (I tried 15 times and then gave up).You can't reach out to support on the Beewi page because this product isn't available on the drop-down option in order to select the product with the problem. That speaks volumes about this product.I'm going to try the WeatherHawk sensor instead.https://www.youtube.com/watch?v=8DIgYor06FQ
