Wyze Outdoor Plug Power Usage Accuracy

I received my outdoor smart plug today. It’s up and running and connected to my home LAN. The reason I purchased this plug was to track the power consumption of my plugin hybrid vehicle that I recently purchased. I’m using the L1, OEM charger by Ford and it is the only device plugged in, on its own electrical circuit. It’s rated at 12 amps. charged the vehicle while connected to the Wyze outdoor smart plug for the first time. It charged for 3 hours and 4 minutes. According to the usage graph on the Wyze app, it consumed 7.26 Kwh of energy to charge to full. The daily graphs are inconsistent from hour to hour. It shows 2.77 kWh at 2pm and 1.7 kWh at 3pm. They should be within a few tenths difference. Prior to using the smart plug I was using a “Kill a Watt” power meter and it showed consistent results over the past month. For the milage that I drove, I normally get below 5 kWh to charge to full. so I’m reasonably convinced that the charging adapter is functional properly. For those that got their Wyze outdoor plug, what are your usage results? Are they consistent? Is it what you expected?

I have mentioned it twice to Wyze support, but they just keep sending back canned responses that completely misunderstand or ignore my concern. In fact, I believe my outdoor plugs are WRONG by a factor of x2. That is, it seems to show TWICE the actual KWh usage. They are rated at 15 Amps. I also have it on a 15-Amp breaker. I’m running a 1500W immersion water heater for an outdoor stock tank. At most, that should be 1.5KWh, but recently my plug peaked at 3KWh for several hours. That would translate to drawing 25 Amps @ 120V. So, I don’t see how it is mathematically possible for it to EVER pull 3KWh. Am I confused on my math? I mentioned this to Wyze support, and after a week or two (I know they have been terribly backlogged), the basic response was, “I understand that you want to check and change the usage scale” (I don’t – I just want it to be correct). The tech went on to give a canned response, explaining the purpose of the Energy Monitoring feature. They completely missed my point. I’m hoping someone at Wyze will see this and at least consider looking into the possibility that their code is incorrect. Again, if I’m mistaken, I will happily recant, but I don’t see how it’s physically possible to ever pull 3KWh on an Outdoor Plug.
