Most accurate energy monitoring plugs ?

December power bills always feel a little higher in my place, so I finally started paying attention to what’s actually pulling power day to day. I picked up a couple of smart plugs just to get a rough idea, but the readings feel inconsistent depending on the app or device.

I’m mostly plugging in heaters, a few kitchen appliances, and some always on electronics. I like the idea of seeing real time usage instead of guessing at the end of the month. The problem is I’m not sure which monitoring plug is actually accurate enough to trust.

For anyone using smart plugs to track energy use in December, which ones have been reliable for real time monitoring and which ones felt more like estimates?
 
I went down this rabbit hole last winter. From what I’ve seen, most smart plugs are better at trends than exact numbers. I use them to compare devices against each other instead of trusting the dollar amount. If one heater suddenly looks way higher than the others, that’s usually enough info for me to act.
 
One easy way to sanity check your plug is to test it against something predictable. Like a basic incandescent bulb or a resistive load with known wattage, then see if the plug reads close. If it’s off on that, it’s definitely not going to be accurate on cycling loads like some heaters and kitchen gear.
