Captive portal causes WiFi problems on sonoff basics

pjmsullivan commented 1 year ago

The problem

After updating my devices to 2022.9.1, three sonoff basics couldn't connect to WiFi. After manually connecting to the devices over serial, erasing flash, uploading esphome, and checking the logs, I discovered the following:

With my binary_fan and captive portal enabled, the sonoff basic could not find my WiFi network whatsoever: esphome no matching network found
With default esphome sonoff basic config and captive portal enabled, the sonoff basic could see the network, but could not connect esphome Event: Disconnected ssid='[redacted]' reason='Probe Request Unsuccessful'
With my binary_fan enabled and captive portal disabled, the sonoff basic connects to WiFi as expected.

UPDATE: removing captive portal from a different sonoff basic does not resolve the issue, it remains unable to connect to wifi. Configs below.

Which version of ESPHome has the issue?

2022.9.1

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

2022.9.6

What platform are you using?

ESP8266

Board

sonoff basic

Component causing the issue

captive portal (I believe)

Example YAML snippet

two configs that cause WiFi failures after update. The first works when I remove captive_portal, but not the second.

esphome:
  name: bedroomfan
  comment: Controls the bedroom fan
esp8266:
  board: esp8285

  ssid: "[redacted]"
  password: "[redacted]"

  ap:

Second config file that does not work after update to 2022.9.0 (worked before):

    min_idle_time: 0s
    cool_action:

    idle_action:
      - switch.turn_off: relay

status_led:
  pin:

Anything in the logs that might be useful for us?

Did the update to 2022.9.0 increase the compiled size that is causing WiFi to be unreliable? I

Thank you so much for this amazing project.

I’m having this same issue with two sonoff basics.

One has a DHT22 and an SGP30 sensor. The other is fairly basic with just the internal relay.

UPDATE: I can confirm that removing the captive_portal: line from the YAML configuration fixes the issue.

I updated the affected sonoffs to 2022.11.5 and the connectivity issue is gone. Thank you.
