DIY home automation lighting has been around since about 1980 and while the advantages homeowners hoped to gain such as convenience, energy savings and security were at times outweighed by the fact that these early systems were not always reliable. These early devices relied on a communication protocol known as X-10 where one light switch or receptacle would talk to the others over an existing household electrical system. As it turned out, X-10 relied on a weak signal that was subject to interference from everyday appliances that would create electrical line noise.
Turn the clock ahead 20 years. Many of those early X-10 systems are still in use today but the technology has advanced tremendously. Enter UPB. UPB or Universal Powerline Bus has proven to be 100 to 1000 times more reliable than the best X-10 systems in existence due to its signal strength and speed, approaching that of hard wired systems.
Many times we’ve been asked “how can I automate the lighting in my home?”. While the answer requires knowledge of some specifics involved, it is well within the ability of those who can safely replace a light switch or a receptacle outlet to accomplish. The next obvious question…
