My Eyedro device came with 200A CTs that were kind of huge.. My house has 50A service, and these were just right!! very small, reasonably priced, super easy to install, and very long wires! Extremely happy with these!

Using ESPHome in Home Assistant for power monitoring. This worked great for 200A main wires.

This product is a waste of money. In order to use it I would need to buy a second Eyedro EYEFI-2 for $159 and not use the sensors that came with it or buy one without sensors for $250. The Eyedro EYEFI-2 should have come with 2 sensors but have a place to connect additional sensors. It would cost very little more to make the Eyedro EYEFI-2 so that these sensors could be used. I have to settle for using a clamp meter in my breaker box.

Very happy with this product. The web page is awesome as well. If your goal is to monitor power usage on independent circuits, this is your product.
