They have a pretty stupid implementation of the thermostat. You can either hold the temp or run the schedule with a scene. You can't just set a temp. LIke you I wish I could set an away scene that sets a temp but does not change my schedule. I have a away temp that sets via the schedule at 8:00AM. The wife and I are both out the house by then on most days. Some days, however, we will leave early and I would like to just go ahead and set that 8:00AM temp, but I want my schedule to keep running so it will change to the coming home temp in my schedule at 4:30PM. I posted a feature request for it back in January of 2017, but it only got two KUDOs so not a very important feature for many people. That being said this is one device that I have kept on Iris because it's been reliable. Also the Alexa integration works well so I can just tell Alexa to change it before I go out the door.
