#Need Smallest Clamps and Module for Power Monitoring Mains.

LOOOOOOOOOOONG story short, I have 3 breaker boxes. I have the other two being monitored via Vue3 devices.. MOST of what is in this box is lights and basic outlets. The heavy lifting was moved to the other two boxes (Minisplits, EV Charging, Laundry, Kitchen, Theater, etc).
However, this is the central input for the power, so I need to monitor these mains so that I understand what our total usage is. Excel is saying it is 2x what it was this time last year, and yes we got an EV, but that doesn't account for this MASIVE increase in usage.

As you can see there isn't much room in the box, it's an OLD house and the box is super skinny. Ideally it would just be two small clamps and a board with Wifi that I can velcro in that spot between the two mains. Worst case I could run the wires through the top and I'd carve out a little niche in the wall and it would sit on top of the box. The main Wifi router is about 10' from that box, so even in the box I think it might be able to get a signal out. OR, like the Vue, run a wire up and out the box, if it's just a simple wire I could again cut out a little area to place it.

Thoughts?

Hi, I use a Shelly EM gen 3. It comes with 2 power metering inputs but 1 clamp and you'll have to buy another one with a spare connector to use it. Besides that, works as a charm. Before buying anything, be sure that the device can measure the max current your installation uses and that the clamp do so. Take in account also the diameter of the wire you are using. General ones are thick

The Shelly works locally and via WiFi, no need to install the app in your phone or creating an account

You only need to install the Shelly add on in HA
