Utility usage says I used more than my forecast when everything was off, how?
So I joined Ohmconnect and have been trying really hard to gain a streak. I was up to a total of 17 streak and at platinum level before the Ohm Hour 2 days ago on 05/28 from 8pm to 9pm. All lights, my fridge, and my thermostat are all smart devices and shut off automatically before 8pm and turned on after 9pm (verified via history on those apps). I wasn't even home during that hour, and my security camera shows everything off. But even still, the data from Smart Meter Texas says I used 0.499 kWh during the hour (mainly at the end of the hour). This makes no sense, there was literally nothing running in my apartment. I'm so bummed because I've lost my long streak and I don't know why. On Smart Meter Texas, the values all say "actual" so it's not even an estimation thing.
Looking at the data, it looks like my "ambient" usage was around 0.2 kWh per hour until around 8:30pm where it jumped to about 0.7kWh per hour. What would cause a jump in "ambient" usage if everything is off and I'm not home?? I've been doing the same things for all my Ohm Hours and my usage has been approximately 0.15 kWh every single time. How could it jump to over triple that amount when I'm not home?
