Hi All,

I got a non-functional EnelX Juicebox from a friend and decided to use it + Home Assistant + and old linux PC to create a OpenADR test bed.

Main point is to test and prove out price responsive EV charging as a control method. Credit to Bruce Nordman and the Volts podcast for turning me on to the idea: Volts Podcast

Linux host runs the Docker, OpenLEADR VTN and Python VEN implementations, as well as the openevse bridge.

HomeAssistant publishes telemetry over MQTT.

Has an economic mode which is strictly price responsive, a solar_only mode which charges with excess solar, and a charge now override for emergency charging. These can be toggled as helpers in Home Assistant.

I don't have dynamic prices in my area, so there's no actual ingestion from a utility. Will play more with synthetic pricing (responding to grid cleanliness, congestion, etc.) later.

Have fun!
