"It's too cold" app not working on Android

Hopefully, this is the right forum. I’m a complete newbie, and I just installed my Smartthing kit in our vacation home. I’d like to us the “It’s too cold” app to be my freeze warning, however the app requires that I fill in the “Turn on a heater” field, but I don’t have any connected heater to select. What gives?

Not sure if this will work, but you can


a) install the app through the IDE and use a virtual device for the heater


b) modify the app to make the heater field not required and publish it for your personal use (also requires the IDE)
