Nice. I would recommend measuring the usage not from what the device reports but from actually measuring at the wall socket. The conversion is likely meaningfully under the 95% efficiency of some tools and that waste is felt as heat. If you convert to 24V from 120V you will have a significant amount of heat as waste which is unreported in home assistant. If you have the option to use a relay it can actually turn the thing all the way off, allowing almost zero usage when not on, but it can be a little slower to respond.
Yea, my guess is just based on what the strip says (12+12 watts per meter)
Only wattmeter I have is an Ikea ZigBee plug, which does draw reporting. Could use that and measure it's wattage
