That’s the Alarm.com Energy Assistant feature. When you have a new account with thermostats or add thermostats to an existing account it will eventually prompt you and ask whether you want to enroll in Energy Assistant (or Energy Efficiency Modeling) which does exactly that. Do you recall getting asked about this and saying yes?
Unfortunately, at this time, once you’re enrolled in Energy Assistant the only way to cancel it is to remove the thermostats from your 2GIG panel and then add them again. I’m told Alarm.com is planning to add more explicit controls of this feature to the user interface in the near future but they’re not there yet.
The good news is it won’t change your settings. It will just temporarily change the target temperature for an hour or two a day and gauge how quickly your home heats up and cools down in response to that. Alarm.com can use this energy model to make recommendations for you in the future. You probably won’t even notice and it’s only temporary. Once it’s completed the Energy Efficiency Model it won’t do that anymore.
