Not very good since update. It start each time I switch on my phone. Bluetooth no stable.
This review refers to the app combined with the Bluetooth thermometer. The app is not really a master piece and has lots of problems. First of, I couldn't find the thermometer with my Z5c, but luckily, I could with my Z3c tablet. The manual is confusing for something which should be quite simple. However, when I got it to work, it seems like it fulfills my requirements. I have placed it in the attic and can download the measurements to my tablet without having to go up there. I receive hour by hour measurements. The connection is not that great with a floor of concrete in between but I'm not sure what to expect from a BLE device which was really cheap. All in all, I'm still satisfied with the product considering it was really cheap.
No stable Bluetooth connection. Connects and disconnects every minute, and for each connect/disconnect you get a service notification. Sucks!
The connection drops all the time to the sensor. Is it possible to have the current temperature as a notification?
This is probably the ugliest app in the world, but what's worse is its completely unintuitive UI.
