SensorBlue 4+

I have used these devices for several years and generally they work OK. The time setting seems to be fixed and varies quite a bit between individual sensors. It would nice to be able to reset it to correct synchronicity. Today the App seems to have stopped working and is giving garbage readouts. I have deleted it and reinstalled it but it still seems to no longer work.

My thermometer worked until the battery ran out, when replaced absolutely no way of re-pairing with the app. Things like this are great until the app doesn’t work and then instantly become junk. Sooner or later your funky plastic thermometer/hydrometer thing will suddenly and unexpectedly become completely useless, you’ll have to throw it away and it will spend the next 200 years slowly disintegrating in a landfill site somewhere, or worse break up into tiny pieces sooner, flush into a river, disperse in the sea, the bits eaten up by fish made into fish fingers you or your grandkids feed to their children. The vast majority of the time all the things this app connects to will be spent as junk, a brief few months they’ll actually work. Don’t do it. Don’t buy in to this evil rubbish.

Nice App, great to have calibration and I also like the way you can reset the readings, which then go into history, great feature.

Note: This App does not update the read out on your hygrometers display when calibration is needed. Although this does not matter as you can still use your hygrometer as a kind of dumb terminal and use this App and your iPhone for the read outs while ignoring the display on your hygrometer (this is irrelevant if your hygrometer does not need calibration)

Thanks to the Dev for adding calibration 5 stars.
