Max-Min Thermometer anyone?

How about a SmartApp that reports max and min temperatures like a thermometer would do using the temperature readings from smartthings with a temperature sensor ?

not really a smart app, but you can export to grovestreams and it can do that for you along with creating some cool dashboard visualizations.

Any luck with this? I’m looking to do something similar.

I already use grovestreams but that requires to log in and check, i’d like to see the info right on the ST app.
