"Bought security through ADT mainly for the automation options that come with the system. My spouse loves being able to turn on and off our lights in different areas of the house while we are gone. We travel often, so giving the illusion that we are home is a good deterrent."

"The Smart Home features they installed, such as thermostat and door locks, etc. do not always work. For example, the Honeywell thermostat can no longer be operated from our phones and is difficult to install. Remote door locks are also unpredictable."
