My homegrown solution is Home Assistant talking to the Lennox API for my system. If my phone moves more than a mile away from the house for more than 30 minutes, then it switches to Away Mode (62℉–82℉), and when I get back within a mile of the house it switches to Home Mode (70℉–78℉). It works flawlessly. It's been months since I manually tweaked the thermostat. When I do need to override it, it keeps that override in place until the next leave/return event.
