WHAT HOUSE TEMP

I purchased a Honeywell thermostat ($150C at Home Depot)that connects to the web via my home network and can be remotely monitored and set. It uses a browser, or an app (Android or IOS). I set the thermostat at 55 and check it while we are away. You can also set threshold temperatures and it will email you if the temperature goes above or below the threshold or if power is lost. I was originally motivated by the ability to turn on the heat or AC several hours before we got home but it is also reassuring to be able to monitor the actual temperature in the house. You can use it for heat, cooling or to turn on the furnace fan for ventilation. There are several other makes of thermostats that can do the same thing.
