Works well, graphs need improvement


I like the app. It works well and after a few hiccups and having to contact support to reset my account things are working well. Reliability and alerts are what make this worth while. It currently takes about 2-3 days for support to respond to an issue, but the quality of support is very good. I would like to see the app add a dashboard that allows user selected temperature and humidity values to be displayed on the homepage instead of having to select each sensor individually. The only real annoyance is the graphs, which have taken a very large decline in usefulness from the web based app that came before; the intervals are much to big at over two hours instead of the user defined interval (used to be as accurate as one minute).

Still a beta quality app after a year

Touchy guy

Seriously, this came out almost a year ago and they promised it would get better with time. He replaced a website that was fully functional with the kludgy app. Now it's time to tell them what to fix.

Responsiveness. As soon as I start to screw with my finger the screen locks up for a couple seconds before it starts to respond again, then jumping much farther than I intended. Almost unusable.

On the panel screen, the left side really doesn't need to scroll, but it does anyhow which only serves to accomplish making the back button in accessible.

On the charts, for rain, the one hour 24 hour in one week data are all showing at the same scale. That's squishes the most interesting one hour data down to nearly a flat line, while the weekly data, which actually is a flatline, goes across the top of the scale. An easy fix would just be to leave off the weekly line.

The table data could be improved by locking the Row and Column headings, so they don't scroll. Then one could see the identifiers and date/time of the data samples when looking at the things at the bottom of the table and scrolling right to earlier data.

Number one suggestion to the app developer: hey, try using the app yourself!

Decent but laggy


The temperatures do not refresh on the app. You need to exit and restart. I have also found that starting to add a sensor, but canceling can also refresh data. I had mine set for every 5 minutes initially. Over 30 minutes went by. I have relocated the internet bridge to about 20 feet from the sensor. It still shows the data about 5 minutes late.

It is a good price for this, but I don’t see why there is no way to ping the device and have it poll the sensors. I don’t need logs of data for home monitoring. What I want is to be alerted if the temp is out of range and be able to check the temp anytime.

Really don’t understand why the app does not at the very least poll the server to get updated values
