SensorBlue 4+

This is actually a really nice app for viewing real-time data and graphs. Unfortunately when trying to export the data to a .CSV file it gives an Invalid Date Format error. Maybe this is because I am in the UK where we use Day-Month-Year? In any case, this bug renders the data logging function useless. If that was fixed I would give it five stars.

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.

The devices are really good. I have eight of them around the house, the batteries (CR2032) lasted maybe a year, easily replaced.

The user interface is a bit clunky and doesn’t always follow current day standards. So, selecting device setup vs device history vs shrink device display is all a bit hit and miss. Not a huge issue once they are set up.

The alarms could do with adjustment. Once the alarm values are set, I think the app should allow the notifications to be:

- off. Displays go red or green if out or in range. But no other notifications.

- on. As above plus notification messages in app. This is what happens now, the notifications personally drive me nuts. But someone will have a use case.

- push. As above and also push messages to the device, so they appear on the Lock Screen etc.

Keep up the good work, team, your products are really good!
