This is an unauthorized and unoffical firmware for the Emporia View Utility Connect device that reports energy usage to Home Assistant and completely divorces the device from Emporia's servers.

Disclaimer

This software is of generally poor quality and should not be used by anyone. When you install the software on your device, it will no longer report data to Emporia. You should backup the original Emporia firmware before installing this.

Installation

Connect a your USB to serial adapter to the port marked "P3" as follows:

Pin	Description	USB-Serial port
1	IO0	RTS
2	EN	DTR
3	GND	GND
4	TX	RX
5	RX	TX
6	+5v	+5v

Note that pin 6 (the pin just above the text "EmporiaEnergy") is 5 volts, not 3.3v. Use caution not to apply 5V to the wrong pin or the magic smoke may come out. You may want to not connect pin 6 at all and instead plug the device into a usb port to provide power, a portable USB battery pack works well for this.

Instead of connecting IO0 and EN, you can simply short IO0 to ground while connecting power to get the device into bootloader mode.

Download emporia_vue_utility.h and either one of vue-utility.yaml or vue-utility-solar.yaml if you have local energy production.

Execute esphome run vue-utility-*.yaml to build and install
