Whole home energy monitor (infosec.pub)

What is the best, money is no factor solution for monitoring home energy. The goal is no cloud. I was using a zwave solution however it keeps falling off the network and now I cant get it back on. Looking to upgrade.

Edit: I live in the states.

If you live somewhere where the electricity company supports it, you can use the Emporia Vue Utility Connect, which is a $40 device that wirelessly connects to the electricity meter. https://www.amazon.com/Connects-Electric-Metering-Burlington-Mountain/dp/B084T6HGNR. Your electrical meter must be a "smart" one that supports Zigbee SEP and your electricity company must allow customers to connect their own Zigbee SEP devices to the meter. I'm in Northern California using PG&E and it works great.

This just measures whole-house usage rather than individual circuits, but it's still useful.

To measure individual circuits, you can use the regular Emporia Vue. This is a device you install inside your electrical breaker panel, so you may want to get an electrician to do it if you're not comfortable in there. They're releasing a new version of it at some point though, so the current version should go on sale at some point too.

Since you mentioned "money is no factor"... Several solar systems allow you to monitor power consumption. I use an Enphase IQ8+ system and it allows monitoring of both production (how much solar power is being produced, both overall and per panel) and consumption (how much power the house is using, either via solar or from the grid).
