Arlec Device not picking up new SSID

ESPHome
1

I have been mucking around with migrating my Arlec PC191HA devices into Home Assisting using ESPHome and mostly it has been going well, however I just noticed that one of the plugs has decided that it really likes the SSID I was using for the setup and not picking up the SSID for the WiFi I have at the back of the house!

No matter what I do (!secret or direct values) it doesn’t pick up the new SSID.

I figure I could possibly get around it by doing a full reset but that is probably going to be a pain for these things.

So any hints on how I can get it to pick up the correct SSID?

I have tried
Clean & Compile on 2 different systems
Turning off the Offending WiFi
Manually inputting the WiFi Name
Manually putting in a different WiFi Name
Unplugging from the wall and plugging it back in again

An example of what I mean is that I have configured an SSID of “My WiFi” but it is using “Configurator WiFi” and no matter what I do I cannot get it to drop “Configurator WiFi”

Below is the start of my config for this device (although it is basically one of 2 for all my PC191HA switches)

substitutions:
  device_name: "arlec_pc191ha_5"
  name: "ARLEC PC191HA 5"

esphome:
  name: ${device_name}
#  comment: ${name}

bk72xx:
  board: wb2s
  framework:
    version: dev

wifi:
  ssid: !secret back_wifi_ssid
  password: !secret back_wifi_password
  ap:
    ssid: "${name} Fallback Hotspot"
    password: "Password"
  domain: .lan

Putting this here so that people know.
It seems that I just had to do the update and if the update didn’t look to “Take” then unplug the device for a while (5-10 mins) and it would then pick up the updated Firmware (with the new SSID)
I didn’t relise this because the other Arlec Switches didn’t have the same problem

Yes, I found and reported that some time ago in another thread. A real pain, and not what you expect :frowning:
I learnt to check the date/time on the ESPHome version reported by the PC191HA when it boots. Occasionally they do update to new firmware straight away.

I have also come across forum threads about the ESPHome Wi-fi not doing roaming properly - specifically if the WAP goes offline the ESP correctly swaps to another WAP … but never swaps back to WAP with stronger signal. At least my testing indicates that ESPHome is no longer picking the WAP with lowest channel number :wink:

Are you using PC191HA version 2 or version 3 ?
If version 3 are you now able to update them OTA ? I gave up on PC191HA with version 3 … too much hassle and too short a product life.
