I have 2 suggestions for product improvement.
1. I’d like to see a notification based upon frequency of use. For example, I have a livestock water pump circuit that I monitor. Occasionally, the water valve assembly gets stuck slightly open resulting in a slow tank overflow and the pump kicks on every few minutes. For this situation an alert based upon the pump kicking on more than 20 times within an hour, would get this noticed. Of course the frequency number and the length of time would want to be user settable values.
2. I’d like to see a filter on the graph page to select a date&time range for the graph. When looking at the graph by minutes and you need to go back in time a day or two, it takes a lot of scrolling.
