Fallback AP not working ESP8266

[autox86]

Hi,

I intended to have the ap enabled with the capative_portal enabled.
Unfortunetly I only found the issue and the implementation of it, but no documentation.
Reference feature request: https://github.com/esphome/feature-requests/issues/86
Reference implementation: #624

Issue:
When connecting to the accesspoint "p3gosund_Fallback_AP" it is often not getting connected and when it connects, the IP: 192.168.4.1 is not accessible.
After some seconds the connection to the AP is lost and I have to reconnect.

1.) Is the documentation about "captive portal" already somewhere?
2.) Does this work with the ESP8266 or is it only for ESP32?
3.) Unfortunately I am not aware how to get the logs, I have a serial connector here for the plug, but how can I get the logs of it?

I use ESPHome (dev) in HASS: Version 1.13.6

Here is my test config for the Gosund SP111 Tuya Plug:

> 
esphome:
  name: p3gosund
  platform: ESP8266
  board: esp8285

wifi:
  ssid: "pidri"
  password: "12345678"

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "p3gosund_Fallback_AP"
    password: "12345678"

captive_portal:

# Enable logging
logger: 
  level: DEBUG

# Enable Home Assistant API
api:
  password: "Update"

ota:
  password: "Update"
> 

Any help is highly appreciated.

Many thanks! 👍
