I was working in a system like this some time ago. I thought that you need a sensor for each appliance. I like the idea of AI to detect the electrical signature of appliances and only use one sensor.
Azaras, thank you for your comment! You need only one device per home to detect all major appliances, this is the main feature of our system. Will you be at the CES? It would be great to have a chat there :) Our booth at the CES is 51841 Sands.
