Got two of these Tapo P110 plugs and neither seem to be accurate at all on energy monitoring, I have a plug with a screen that has been quite consistent when being compared to electricity counter on the wall (I done daily then hourly readings from one day to next testing with and without PC running) but both off these plugs don't seem to be either reporting or recording properly.

Today for instance I turned on PC and after 1h of idling the energy plug with screen was reading 0.126kwh usage but on the tapo app it was showing less than 0.1 and using the WATT app it was showing 67wh of usage so far, also in the Tapo app it was recording current power draw as 61w but upon going into the graph it was reading the peak as 47w being the highest draw.

Anybody else got any wider case studies of their own?

Edit

3h Gaming PC been on now,

big plug shows 0.427kwh

Tapo App 0.3kwh

WATT App 262wh

Edit 2

Big plug 0.684

Tapo App 0.4

WATT App 430

The gap is getting bigger as time goes on, I have been playing world of tanks for an hour there is no way the spike should be that short, there should be a nice levelfor that hours period.  World of Tanks consumes at a minimum 80w on GPU alone sitting in garage based on hwinfo for PC and the big plug registers sitting in the garage ~160w draw so there is no way it should look just like a spike on the graph it should be at a consistent level throughout shouldnt it?

Also, really, I cannot use the proper spelling for something?
