Just something to think about if your already planning on spending in the near future.
from wikipedia:
The nothing to hide argument is a logical fallacy which states that individuals have no reason to fear or oppose surveillance programs unless they are afraid it will uncover their own illicit activities. An individual using this argument may claim that an average person should not worry about government surveillance, as they would have "nothing to hide"

Thr Meross unit was great! No huge bells and whistles. But it just works... (i'd say even more reliably than MyQ, had it for 3-4 yrs before the switch!)
If you know very little about a topic, maybe just read and learn first.
Different class of product but I'd consider them again for something else.

Completly local and private, no monthly cost, no cloud server, etc.
The only issue is with only 14 CT clamps I didnt have enough to monitor my entire panel, this item has a few more connections so that has my interest but not worth changing my setup for.
I simplty did some configuration in the app that basically said (total power - (sum of all connected circutes)) = Unmonitored Energy.
So for the not so important circuits I know how much they are, just not individually.

I have used it to check if I left a heater on or not when I left the house for a trip. It can save you some time in running back to the house to check.
Yes it can, but I felt more uncomfortable in breaking the tamper seal on my electric meter and unplugging the meter.
