It would be useful for seeing trends in humidity, temperature, battery usage, power usage, motion and so on. Adding it as a general feature of devices that emit ‘graphable’ numbers would be really useful! I use it with my leeo device a lot.
People do this a number of different ways. You can use the quick browse lists in the community – created wiki and look in the smartapps section under “logging.”
I think Simple Event Logger, which can log to Google sheets, is one of the most popular, but there are several different options you can look at.
The following thread also goes into more detail on several different options, including ones that require a paid subscription:
If you’re willing to write your own custom device handler, you can actually include a graph directly within the SmartThings application by means of a
htmlTile and querying the device’s history from the servers.
The DTH I wrote for my solar system does this:
Thanks for the suggestions guys. I ended up using the google sheets one.
A in app 1-7 day history of graphable items inside the app would be pretty cool as a standard feature
I just cannot understand why this is not standard functionality of Samsung Smarthings. It totally evades all reason. What could be more simple than to show a graph of the latest 10 or 100 readings from a numerical sensor?
Every other competitor does this. E.g. Zipato and Fibaro. For free.
Agree 1,000%. When Smartthings was an independent company back about 6 years ago, the app had a lot more features than it does now. I find that in general, Samsung’s software is stodgy and limited. I get the feeling that Samsung’s developers are either writing in FORTRAN, or else they are in some ivory tower somewhere and don’t get out and talk to people much. It’s a common theme among all their products.
