At what point do you just give up on Device Detection?

@oasis Two weeks is a short time for detection to really establish itself as @JustinAtSense points out. You may well have a more difficult home for Sense success. Many users, myself included, have seen significant advances in detection (disaggregation).

My house is non-standard in so far as in the early days I had to inform Sense, via support, that my hot water heater was not being found. It turns out that it was because my supply voltage is 208V and so the phases are at 120deg vs 180deg. I believe Sense has incorporated this type of low-level recognition into the setup sequence. There are many pitfall permutations (the basic physics stuff of many varied electrical networks) that Sense has ironed out, before you even get to the disaggregation layers of the machine learning (RNN).

I recently did an analysis of my hot water heater detection you may find informative and optimistic.
