Recent announcements by Google that it is developing the Weave communication protocol are expected to make waves in the building automation ecosystem, possibly to the chagrin of incumbent equipment manufactures for commercial and home equipment. Weave is centered on Brillo, the Google-developed lightweight operating system, essentially a minimalist version of Android. With Weave, Google may be trying to quickly capture the mind-share of end consumers who want and answer to the question, “how can I quickly connect all of my home systems?”
With Weave, all Brillo devices (and Nest) are self-discoverable, making them, in theory, plug-and-play. A consumer could connect the new wireless door lock with the wireless lights, all through an Android phone. The proposed ease of connecting devices was introduced in Navigant Research’s recent Home Energy Management report, as being a challenge for consumers. This integration is contingent on the wireless protocols being interoperable, as mentioned in a recent blog.
For equipment manufacturers that sell into the commercial markets, Weave poses a threat in two ways. First, this is yet another communication protocol to incorporate into equipment, adding a step to the integration. On the commercial side, integration firms have been stepping up to manage that issue. Weave is not the first extensible system to be developed with an easy user interface (e.g., Android) in mind (see Apple’s Homekit). Weave’s approach is not anchored on iOS, of course, and is therefore more open.
More significantly, the entrance of Google and Weave are expected to force the small and medium commercial market suppliers into a quandary. The small and medium commercial market is vast, and is in need of energy and cost-saving solutions. These customers do not have the funds to invest in large solutions, and in some ways are like residential consumers; HVAC does not keep them up at night. In this light, do original equipment manufacturers (OEMs) keep selling single end-to-end building automation system solutions, focusing on the value of a single integrated system, or do they appeal to the ease of integration with a solution like Weave? Most small or medium-sized commercial building owners or tenants have heard of Nest. But how many have heard of BACnet or LonTalk?
During a recent Lightfair panel discussing the promise of convergence of the Internet of Things (IoT) and automated building controls, it was reiterated that IoT-based building integration solutions exist, and are being deployed. The linchpin in wide-scale deployment will be people wanting easy solutions. Weave is certainly going to push the adoption wave; it will be interesting to see how integration solution providers and OEMs respond.
