ESP Bin patcher (+ Web Install)

Patch an already compiled ESPHome / ESP-IDF software image and upload the resulting file to your ESP device from within the browser.

The source YAML can be modified to contain special placeholders. Those placeholders can be auto-detected and give you the most options for modification.

Patching already compiled software also works without the need for special placeholders, with the limitation that the replacement string cannot be longer than the original value.
