[Question] How to dynamically update Wi-Fi credentials without re-flashing?

[Runninginsilence1]

Description

Hi there,

I am a beginner in ESP32 development. I will continue to research this topic on my own while waiting for a response; if I find a solution or realize the answer is documented elsewhere, I will close this issue myself.

I have successfully flashed espectre onto my ESP32 by following the "Development Setup" steps in SETUP.md. One of the steps involves creating a secrets file to define the SSID and password before building and flashing.

My question is: Is it possible to dynamically modify the SSID and password on the ESP32 without having to edit the config file and re-build/re-flash the device every time?

I would appreciate any guidance or suggestions on this. Thank you for your help!

Hi @Runninginsilence1 ESPectre already supports dynamic WiFi configuration without re-flashing.
The example configuration files (e.g., espectre-c6.yaml, espectre-s3.yaml) include:

• Captive Portal: If the ESP32 can't connect to WiFi, it creates a "ESPectre Fallback" hotspot. Connect to it and configure WiFi from the web page.
• Bluetooth (Improv): Use the ESPHome app or Home Assistant Companion app to configure WiFi via BLE.
• USB (Improv Serial): Use web.esphome.io → Connect → Configure WiFi.

The secrets.yaml file is only required for development configurations (espectre-c6-dev.yaml). For regular use, just flash any production file (without secrets.yaml) and configure WiFi dynamically using one of the methods above.

See SETUP.md - Configure WiFi for details.
