Hi Jack,
While I prefer the suggested visible reminders, just last night my sister-in-law showed me the “Reminders” app on the iPhone, probably something similar exists on non-iPhones, as well. 

Just stumbled through the app (trying to remember what she demonstrated just 8 hours earlier). You can set a reminder based on geographical location (i.e., the reminder goes off when you phone’s gps reaches a location). So, you set a reminder every time you arrive home that reads, “shut your top vent so it doesn’t cost you another $100”, that sort of thing. 

Good luck!
