Does what it says on the label
For BLEThrowie
I bought the BLEThrowie as a way to have a simple to use remote monitor for temperature and especially humidity, and that's exactly what it does. I took it out of the package, installed a battery, downloaded the app to my iPhone and started seeing data points. Once I got done showing it off and explaining how it worked to anyone who looked remotely interested, I put it on a shelf in the basement and it's been happily logging data points ever since. The only feature I'd like to see is the ability to export the saved data points to an external file on my iPhone, ideally to Dropbox since that would be the easiest way to get it off the phone. But that isn't essential for how I'm using it, I just have to remember to look at the data before it ages out. I expect to order a couple more to monitor other places in the house, too.
