WiFiManager

WiFiManager is the maintained ESP8266/ESP32 configuration-portal fork used by DeviceFramework. It is a deliberate breaking fork of upstream tzapu/WiFiManager, with a streamed single-page portal and typed JSON APIs rather than upstream’s legacy page/template model.

Why use it

Single-shell portal: one responsive SPA for WiFi, parameters, information, actions, and firmware update flow.
Data-first APIs: portal state and actions are exposed under /api/..., not scraped from HTML.
Controlled portal UI: semantic identity/theme values and structured portal APIs without exposing portal internals.
ESP8266 and ESP32: clean PlatformIO consumers resolve the right asynchronous TCP transport automatically.

Try it

#include <Arduino.h>
#include <WiFiManager.h>

WiFiManager wifi;

void setup() {
    Serial.begin(115200);
    wifi.setConfigPortalTimeout(180);
    if (!wifi.autoConnect("Device Setup", "change-me")) {
        ESP.restart();
    }
}

void loop() {}

For a DeviceFramework device, configure the framework’s shared device password instead. DeviceFramework applies it consistently to the provisioning AP, OTA, HTTP Basic authentication, and WebSerial.

Brand it

const char kTitle[] PROGMEM = "Set up Temperature Monitor";
const char kBrand[] PROGMEM = "Tree";
const char kAccent[] PROGMEM = "#347a45";

const WiFiManagerPortalConfig kPortalUI = {
    WiFiManagerPortalText::progmem(kTitle),
    WiFiManagerPortalText::progmem(kBrand),
    {}, {}, {},
    {
        {}, {}, {}, {}, {},
        WiFiManagerPortalText::progmem(kAccent),
        {}, {}, {}, {}, {},
        10, 0,
    },
};

void setup() {
    wifi.setPortalConfig(kPortalUI);  // before the portal starts
    wifi.autoConnect("Device Setup");
}

The full standalone example, including a static SVG, is BrandedPortal.

The suffix after # is a Git ref. PlatformIO clones the repository and checks out that release tag; GitHub Release assets are unrelated. This repository is supported through PlatformIO. Use a local symlink:// or file:// dependency only while actively changing this fork.

Development and releases

./scripts/test.sh compile --platform esp8266
./scripts/test.sh compile --platform esp32
./scripts/check-docs.sh
./scripts/prepare-release.sh vMAJOR.MINOR.PATCH --tag

Tagging repeats the board-free compile checks, validates the package, and creates a GitHub Release from the corresponding changelog section. It does not publish to the PlatformIO Registry or deploy firmware.
