It’s been an odd month for Smart Energy, or at least for the wireless standards that are tackling connectivity around the home. If you were to go back six months, then, at least in the U.S., the general consensus would have been that ZigBee had the market tied up. It had the only profile with “Smart Energy” in its name and was winning the PR battle hands down.
Within the major working groups, things weren’t quite so clear. NIST, which has been trying to herd the wireless cats into some semblance of order started a more thorough analysis of just what existed, which saw an increased emphasis on other members of the IEEE 802 standards family, bolstering the fortunes of Wi-Fi (in its 802.11 incarnation) and Bluetooth (in its 802.15.1-2005 form). And it made its preferences clear about a need for IP support. But the status quo didn’t seem to shift very much as a result.
Then, last month, Bluetooth emerged from its normal mode of PR silence to announce the formation of a Smart Energy Study Group. The fact that Emerson, one of the world’s leading manufacturers of home HVAC devices was one of the sponsors for the group caused some noticeable shivers in the Smart Energy marketplace.
This week, there were more ripples, when Wi-Fi and ZigBee announced their Alliance of Alliances to jointly provide an in-home solution for Smart Energy. The Twitterati thought it significant, but what was behind it? Is it deadly rivals joining forces against a common enemy, or is there more going on?
