We have worked very hard past few weeks to bring you a new app mode called "Trends": 

It is available in web and Android interface right now by clicking the "Temperatures" button on the upper right corner, and on iPhone/iPad app (version 3.0.0, expected to appear in App Store sometime later today), by swiping to the left, or pressing the "Trends" button on the tag list screen. 

The mode summarizes each sensor's temperature, humidity and ambient light, along with recent trend in a carefully designed layout. If monitoring is enabled, the too hot/cold regions are displayed on graph with red shadows, too wet/dry region by green shadows and too bright/dark region by blue shadows to show how much margin there is to abnormal conditions.

If event history was viewed (loaded), motion events such as "opened", "detected" are overlaid on the recent temperature graph, to help visualize possible causes of temperature spikes (iOS only).

Special server side data structure was designed such that recent data points used for this screen is always readily available, to ensure very fast screen load speed. 

We have overhauled much of our iOS app, so that it loads faster and supports iOS 12. On iPads, the split screen width now automatically adjusts to an optimal value, depending on what is displayed. App will automatically resume updating screen as sensor data comes in, when network connectivity is interrupted and later restored (the Web/Android version was already behaving this way). 

We are all ears for your feedback, and any ideas to make the app work even better for you.
