esphome
Custom component for ESPHome to add support for the Emporia Vue 2 energy monitor (by emporia-vue-local)
I've had great success using home assistant's built in energy monitor dashboard and a ESP32 based power monitor from CircuitSetup. Home assistant supports exporting metrics via Prometheus which I then graph using grafana for fancier dashboarding.

Not Tasmotized--ESPHome!
Instructions are at https://gist.github.com/flaviut/93a1212c7b165c7674693a45ad52..., and I'm around in the discussion forums at https://github.com/emporia-vue-local/esphome/discussions to help out with getting this set up.
And I agree--it's really a great deal, and it's the only one of these products that comes with UL listing and can run open-source firmware.
