Not gonna try to represent Sense here, but though there are seemingly a huge number of smart devices for the home out there (switches, hubs, etc) that Sense could integrate with, there are only a small number that have characteristics that are useful for supplying “ground truth”:
- devices that provide actual measured power usage. Most smart switches only tell if something is on or off, not the power flowing through.
- speedy and non-laggy communication with the Sense monitor so Sense can get a once every two second power reading. Most smart devices communicate via zigbee/zwave and would have bottlenecks and latency if a dozen or so smart devices were trying to communicate to the Sense via a hub.
And if you look here, you’ll see how each different smart device system has their own unique integration approach, making it expensive to add and support each new flavor:
