The big decision facing anyone looking to venture into home automation for the first time is, “Which technology is the best?” The choices can seem overwhelming. X10, A10, UPB, Z-Wave, and ZigBee are some of the most popular technologies. A novice user may be inclined to lean toward X-10 because it’s been around the longest. Although it was useful in its day, it was slowly replaced by more reliable protocols.
Wired Technology at the Beginning
X-10 led the way with power line communication and was considered the father of modern home automation. Plagued with problems of poor performance, distance limitations, power phase limitations, and sporadic reliability, several manufacturers picked up the gauntlet and worked to improve power line communication reliability. Some manufacturers, like Advanced Control Technologies’ A10, sought to improve the X-10 signal while others developed their own proprietary power line protocols, like Powerline Control Systems’ UPB protocol.
Wireless Technology Emerges
The easiest way to overcome the inherent problems associated with powerline systems was to go wireless. Protocols like Z-Wave and ZigBee challenged X-10 systems with higher reliability. As the popularity of wireless technologies increased, third-party manufacturers rushed to join the expanding market. X-10 powerline systems faded further into the background.
Hybrid Systems Also Developed
Although few pure X-10 systems are in use anymore, hybrid systems consisting of X-10 devices used with wireless Z-Wave or ZigBee products are still popular. The reason is simply that many X-10 devices still exist and few home automation enthusiasts are ready to toss them out yet.Anyone following the release of new home automation products are quick to notice that the bulk of new product development is in the area of wireless devices. It won’t be many more years before X-10 devices join 8-track players as the newer wireless technologies replace these aging devices through attrition and system upgrading.
