JINOU Bluetooth Low Energy 4.0/4.1 Beacon/iBeacon with Sensor, Wireless Humidity and Temperature Sensor. For Android/iOS

(so far - I've only just started testing)- Temperature is slow to react, but settles down to something reasonably accurate.- Battery reading fluctuates a lot (>30%) - not sure how reliable that value is.- Seems only 1 device can read from the sensor at a time (i.e. once one device is connected, no others can connect)- Worked fine with apps: nRF Connect (iOS/Android), Light Blue (iOS/Android), JINOU Inductor (Android only - supplied as an APK on a USB stick that comes with the sensor)- Documentation (on supplied USB stick) didn't cover all of the configurable service values - tells you enough to use the main features (sensore readings & controlling measurement frequency/stop start measurements)- connection seems stable - haven't tested range yetThere's a desktop app "nRF Connect" from the chip maker that I'm going to try, which is free (scratch that, it requires a specific dongle to work).Overall this version of the sensor seems to be working. Not sure how good battery life will be, but it's functional.

When I first got this delivered I clearly hadn't seen that it didn't come with any batteries, so after ordering and having these delivered, I tried to test the app that came with it but it wouldn't work correctly on my Pixel XL3 so I contacted the company and they have sent me a newer version which works fine.Any questions I've had regarding the product have been very quickly answered - the email service has been first rate and I can not say enough good things about them.With regards of the quality of the product, it does what it says but the quality of the plastic doesn't seem great but everything works which is all I need!
