Emporia Vue energy monitor

Emporia. All the way. Installed a ton of them, they work like a charm. Also have a decent plugin for HA through HACS that correctly enters CT sensors under the “Energy” section in HA.

For example, I know that my living room breaker is all LED bulbs and a TV, so I put a Shelly plug on the TV and track it's usage from the EM plug. Now I know the TV uses X and the sum is Z, so the bulbs use Y. All of this goes into a Sankey chart in my home assistant. I also have a server rack with a Unifi PDU so I can track the usage of each of my servers and remove that from the basement power …

Emporia Vue Has a cloud based integration updates every minute. But is flashable to ESPHome. Priced low to high. Im using the SEM-Meter currently and tracks as well as the Emporia Vue 2 I had installed that is now in use at my parents house so mom can track her usage. I ordered the Refoss before I had the SEM and is well outside the return date so Im gonna see, hoping, if the WiFi reaches the remote meter base to install out there.
