I would like to introduce you my latest Arduino library:
https://github.com/prampec/IotWebConf
It is a little bit similar to WiFiManager, but built with some other goals in mind. E.g.:
- non-blocking operation,
- config portal also available in WiFi mode,
- your custom configuration properties are also handled by the module,
- developers has more control over the config portal and the states.
Now also available form Arduino Library Manager.
I hope you find it useful.
All feedback are welcome!
Cheers,
Balazs
