I looked over the measurements and they were actually correct. I just read the amps incorrectly at a certain point. I verified with the meter I have attached to the wall.

As far as Crypto Mining in the house you have to be careful and understand how much power consumption the mining rigs use and to spread the load around the house initially. I used the Emporia to analyze the usage and found my self lowering my electric bill even after running a mining rig for a few months. Pretty amazing.

The next phase was to use an old basement abandoned dryer 250v electrical box I had in my basement. I wanted to see if it was used over time by anything in the house. The installation on the Emporia made me get motivated and document all my circuits and backup generator links. I now have a detailed picture of all my circuits and back up leads most of them are monitored.

Once I felt I the dryer circuit was not used anymore, put a new socket NEMA L6-30 and a  DROK 80-300V in an attached box to see the voltage locally in front of the mining rig as most miners do. I found the PDU meter, the DROK and the Emporia all gave me good readings however I noticed that in the charting on the Emporia I could see some of the miners components behaving badly from an electrical standpoint. This was not picked up by the mining software. I would lose a video card and the voltage would drop dramatically. This lead to adding alerts so I could modify my configs. Usually this is because you are pushing these video cards too hard or undervolting them too much etc. Mining is about power to performance ratios as well as power/performance  to reliability.

That being said I love having the ability to know when a miner goes offline of a period of time or the wattage drops and I can tell there is an issue. This is important if Im away from home as I cannot always reboot the rig if the software locks up and I have been able to catch this with voltage drops. On one rig that runs on 120v I use my Insteon wall socket to remotely powercycle that circuit. On the 240v mining rigs I think I have now tuned them to the point where the rig itself can respond to issues and reboot itself.  I then use the Emporia to alert me and is a great back up to know rigs are having issues.

This product is so sensitive I can actually see in a multi GPU mining rig that the wattage fluctuating means trouble is coming and a card is behaving badly.

My plans are to use another  Emporia at my shop as Im building a larger production mining rig and feel I could not live without this visibility. I work with a lot of network monitoring products in my day job and we always say “you cant fix what you cant see”.

As a bonus I use the monthly measurements by dollar to charge back my business for my specific electrical usage. The miners in my house and at my shop are in shared environments and pealing off usage that is specific to the mining business is nice for accounting proposes. My shop is a separate business with separate partner.

Emporia is  the best internet IOT/OT product I have used in a long time and could spend hours talking about uses cases.

Thanks.
