Good point @joeciarcia - if you have additional automation requirements, you might choose to deploy a smartplug or commit an entire HS300, beyond the measurement benefits. I did the same - I put a doorbell with a Ring camera on a Traveler Kasa EP25, but eventually kept it on the doorbell, because it seemed to need a power cycle every once to keep online. So I do an auto power cycle ever 7AM.
Based on my experiment with another Traveler, it looked like my OLED TV usage was more driven by video processor usage than screen luminosity. A static image occasionally had massive dips in usage.
