Looking for the best ways to monitor ongoing electric use in residential mining?

Hello everyone,

I’m starting a small home mining farm and I’m trying to determine the best way to document the electric costs. I have an LLC and I’d obviously like to write off the electric bill each month, but I need to separate the mining electric use from my personal home electric use.

I have a combo of GPU miners, Goldshell box miners and full sized Asics as well.

Any input, tips or ideas are welcome! Thank you

Dont have to have your house electric bills for the last 2 years? Example is like December 2020 was $300 and December 2021 was $600. Then if you have December 2019 to compare that is even better.

I did a watt test also on the main inbound leads and depending on how many miners are online it went up 6000 watts for what was running. So you remove all the miners and do the test with only the typical house stuff running… including the AC or the heater for this test. Mine was 4500 watts there about. Then add the miners and take the readings again.

You can also buy all kinds of watt monitoring devices that log to a excel type log file and download that from each device and figure on the watts used per month on ASIC and call the rest off the electric bill personal.

Thank you for the input. Im having a difficult time finding a watt monitoring device that will track numerous circuits (minimum 4 circuits)…any recommendations?

a good old analog watt hour meter is what you want. cost you about $100 for meter & the base
pretty easy to add if you already have a sub panel installed for your mining operation

I also have some box miners but I just run them off atx supplies that allow for a 220v input so I can keep everything on 220. I really like this system, easy setup, good price.

Its on amazon, “Emporia Smart Home Energy Monitor w/8 50a Circuit Sesors” (the link was super long so I didn’t link it)

I’m in the same situation, I’m using residential electricity for mining under an LLC and I have chosen to go the simple route. I’m using the manufactures electric estimate (i.e. 660 watts for a Goldshell X5 low setting) and adding up all my miners’ wattages per hour. I also have an amp meter on one of my 240v C19 power distribution units where I can check the approximate watts through conversion. My electric bill has 3 time-of-use rates throughout the day, so I just average it out for a 24-hour period. Then at the end of the month, I bill the LLC for the total Kw times the (electric rate per Kw) and get reimbursed by the LLC.
