I purchased the sensor and downloaded the app to monitor indoor temperature to stay compliant for Cal OSHA regulation. The one feature I was hoping the app would have would be a notification if a set temperature threshold was exceeded. This is not the case The only time I get a notification is when I open the app making it useless to me. Getting notifications would be such a great asset if you can get them while the phone screen is off.

Plots temperatures and downloads them and humidity OK (slowly) from the hardware but only when you open the app - no auto download. Allows swapping of view between sensor charts and creates CSV file of data for spreadsheet use. Charts are inflexible and default to the wrong time view. e.g. you've just loaded new data and it shows a view half way along a 100 day series EVERY time, so you have to scroll to now EVERY time. Stable.

I like the presentation and how you can add images. I have 5 Bluetooth thermometers. However, when I click through to see the graph and I haven't opened the graph in a long time it takes a very long time to retrieve the data. There should be an option in settings to set the amount of data to be retrieved to less than all, for example 7 days, 30 days etc.
