Smart Thermostats help us regulate temperatures if we are home and want to keep things consistent also while we are away and not using the system. They are also especially helpful for when we have tenants, and we are paying the utility bill. Smart thermostats can set a temperature not to exceed in addition to sensing when someone is not home so they can turn off the system.
A few utility companies including LADWP reimburse for the cost of the thermostat up to a certain amount.
