Honest impression
Hi folks, a few points that I am sure you have heard before. My system has been up since mid March. It regularly mis assigns roughly 50% of the dryers usage, the electric oven is also missed by about 50%. As I understand, the algorithms look for a sharp rise and an equal fall to identity devices and this makes sense. More difficult items to identify must drive you nutzzz. I don't suspect my inverter driven heat pump will ever be identified.
In spite of the things it will never get correct, I think it is still light years ahead a device with ct's on each breaker that will never identify individual users of current. All in all it does what I need, shows the PV output, household use and grid in and out.
Keep on trucking!
