Anyone working on getting esphome on emporia Ev chargers. I saw they have beeen succesful with energy management device but that are not same
The Ev charger has esp32
Well, for anyone curious the basics are this.
The energy managment wasnt a large rewrite of the code but it seems to be a task. I belive there may be a simple (not so simple" way.
The Home device was looking to connect to a default wifi network
SSID: emporia
PASSWORD: emporia123
Not sure why that was but they used this and found it was passing messages to a mqtt server.
They decomplied the firmware and figured out the memory location for the SSID, PASSWORD, MQTT server IP and credentials. They then simply rewrote those memory locations.
I read several writeups about evse and home equipment so I am not sure if this is what is used on the home items but I am certain this method was successful to access MQTT message data from this or home unit and likely works for EVSE.
As a noob approach it may be possible to setup this network and setup a MQTT server with the default credentials. not prefered but could work. I dont have defaulted unit and believe this stops functioning after unit is no longer defaulted. Also realized that these thngs cannot be factory reset so curious if anyone who gets one of these in future can verify if wifi credentials above work on NEW device?
