1. Home automation is notoriously complex. This is especially true when it is designed for convenience sake, rather than for practical reasons. For example, home automation systems often allow you to control the lights in your home from your cell phone when in reality, this is often more simply done by flipping a switch, and at much less cost.
2. Home automation can also leave homeowners vulnerable to a different kind of security risk. While automated security systems may reduce the risk of a physical threat from an ordinary burglar, threats from hackers who may want to access control over aspects of your automated system, such as your personal video surveillance systems, are more difficult to prevent.
Home automation can also put homeowners at risk of becoming over-reliant on automated security systems and less likely to be vigilant about security. It still remains important for homeowners to uphold their common-sense when it comes to security and using their automated systems.
3. Automated systems are very expensive. This depends, to an extent, on how complicated and comprehensive you wish your automated systems to be. For homeowners on a budget, these types of systems are often not worth the long-term cost that comes with updating and maintaining home automation.
4. Some smart devices are incompatible with automated systems. Ideally, home automation systems in a home should be controllable from one device. However, this is often not the case as not all smart devices can support all types of automated systems, which means homeowners may need to buy more than one smart device to control an area of the home.
