I don't understand why would you want to invest a lot of money doing something that might might "unnecessary" , it's not like the gears will consume different power everyday , unless I am missing something!
here is the missing part...
I was going to install it in my mom's apartment (back once per 2 months +-) and the building has some regulations about the electricity. Because of safety in all aspect, I will place it in my friends warehouse that it's in another city.
My safety concern is the installation, fire, comfort. I saw some news that some people burned the building, got fined because of regulation, etc....
Like I said above, smart plug are not industrial and some people reported burned, so imagine if I plug it to an Asic miner.
Or you could get a metered PDU to test the miners on - https://www.geistglobal.com/products/power-distribution/metered-pdus
Yea I was looking on some PDU but... too expensive and not really sure if will be suitable for me, too many options with upgrades and it's used on servers.
After all research I saw something really interesting...

That's what I'm looking for but the price is little too high, if I can get it with the shipping fee, it will be like a PDU price. I didn't have time to check the other 2 models, it might be the answer...
