About this app

The Smart Hygrometer Thermometer is the easiest way to monitor the humidity and temperature conditions affecting the things you are about.
Just quickly pair the app with the humidity-temperature sensor.
Then you can check the current temp and humidity status of the environment.
You can connect more than 100 devices in your app.
If you want to use data, you can export your entire history to CSV for analysis. It records the data every 10 mins.

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.

Just discovered the logger! This app just opened a whole new world! It records the temp and humidity over time and provides the info in simple and easy to understand graphs. Lets you monitor what temp and rh there has been throughout the day, throughout the week, how many cumulative hours in the different temperature / humidity ranges. It's not fiddly (although it took me a while to actually try the logger, don't be like me!), it's easy to pair, and doesn't have a million settings. Recommended!
