I've had the Sense Solar for about six months now, and really appreciate the product. I have an older solar system that is not networked, and with the Sense, I can now see up to the second energy production from my phone. It's great! It's also educational to see the power production in comparison to our power consumption in the same graph. The home device discovery continues to identify products within our home, and teach us how they use power. Seeing our power consumption has changed our behavior a little bit, and we're using less power now than before Sense. Overall, the device does what it says, and the experience gets better as the Sense team improves the visualizations in the app and online.
Bottom Line: Yes, I would recommend this to a friend
