I’ve had a Sense installed in my 100% electric, new house for 1.5 years. In that time it’s found devices, lost them, found them again, and lost them again. And…repeat endlessly. It has proven itself to be remarkably unreliable regarding device detection. It finds things that are 100% correct and then loses them within a few weeks. It CANNOT find Mitsubishi Mini-split HVAC units at all, and I have two of them. They represent approximately 75-80% of my total energy consumption, but they can’t detect them. Really? They run nearly every day of the year, but Sense can’t see them? They run on completely different circuits from everything else, but Sense still can’t find them. And machine learning is supposed to be better than a clamp sensor because… what? I know commitment to an idea is a good thing, but there’s been no noticeable improvement in my Sense in 1.5 years. That is NOT an impressive accomplishment.
In Sense’s defense, I will add that it’s been very good at detecting “always on” load. And the solar measurement seems quite stable. But it should since there’s nothing to detect but current flow. The App is pretty nice, but no matter how good it is, the lack of data detection is crippling.
I’ve already chosen a replacement monitoring system. It won’t be using machine learning. Just simple circuit level power flow measurement. The day may come when machine learning trumps all, but as of now that day is still below the horizon.
