As far as I know, we’ve had pretty good luck with model S and X. 3 is still pretty new so we just don’t have enough data to make major advancements on that yet. Have you worked with support at all on detecting your S?
@vespula, I can’t speak to specific models, but the data science team is working very hard on improving overall EV detection. It is a major undertaking however since EV signatures look very different from normal, quick-transient household loads.
