If you're looking to install open-source, cloud-free ESPHome firmware on your Emporia Vue 2, you can find those instructions here.

This is a companion repo to my post, "Reverse-engineering the Emporia Vue 2". If you haven't already seen that, it may provide useful background.

It contains no flash dumps, ELF files, or any other Emporia proprietary material.
