Sadly, the app is fundamental and poorly translated, it’s a must to dry the detector to cease the alarm, and it took too lengthy to warn me when it went offline (weirdly, the offline detector is toggled off by default within the app settings, so I needed to change it on). You will get this a bit cheaper by shopping for straight from Monoprice.
