Local Control for Emporia Vue

The Emporia Vue is an excellent piece of hardware for measuring your home's electrical consumption. Critically, it has a UL listing that proves that it has been designed and tested to be safe, something many hobbyist solutions lack.

The goal of this project, and this guide, is to help you get (unofficial) Open Source firmware running on your Emporia Vue so that you can control it locally from Home Assistant. This gets you

  • faster update times
  • fully offline function, with no internet requirement
  • the ability to automate your home based on your power consumption, to, for example, handle time-of-use billing

It is an unofficial project, so you should not expect any support from Emporia on your flashed hardware.

danger

Working with mains electricity is dangerous

You should not attempt flashing the board while it is connected to mains electricity, for both your and your computer's safety.

Electrical panel work should only be done by a qualified person.

Supported Hardware​

This project supports both the Emporia Vue 2 and the Emporia Vue 3.

What you need​

Flashing tools​

All of these are valid options, but different people will have different skill levels and different tools already on hand. Use whichever technique is most convinent for you.

Solder headers (Vue 2)​

Clip technique (Vue 2)​

See clowrey's community post for details.

BDM Frame (Vue 2, Vue 3)​

See digiblur's guide here. It's for different device, but the concept is the same.

Ideally you would want a BDM frame with 6 probes.

Soldering (Vue 3)​

You can carefully solder on jumper wires but note that the pads are fragile!
