This is one of those things that's really cool and could be very useful but probably not worth the effort.

I'm not saying everyone should own one of these but if you are going to be in your home long term I think it's a worth while add.This winter I had some small part go bad in our heat pump system which caused it to switch to the aux heat. It was maintaining temp fine so a month went by and never noticed. Having this or something similar would have allowed me to catch the jump in usage immediately. Our bill was high enough that month that it would have paid for this and then some.

If your power company has installed a smart meter outside, a simple home energy monitor like this https://rainforestautomation.com/...ng-unit-2/ would work. No wires to run, just send your power company the ID off of the device, power it up, and it will sync with your meter outside.

A completely different product than what this deal is for but will accomplish 75% of what most people would need.

The value of the Meross and similar products is that it helps identify power consumption by circuit. That way triaging issues is narrowed down to a limited number of devices, rather than the holistic house utilization.

Yes that is the value of it.
For those who are lazy, can't install this product themselves, or cheap, you can just utilize a energy monitor linked to your smart meter and turn off circuit breakers 1 by 1 to find the phantom draw.
