PFL12 Red/Blue Flash - offline now

[Node815]

This is my ESPhome YAML file for this plug:

---
substitutions:
  name: dishwasher
  friendly_name: Dishwasher
  disable_entities: "false"
packages:
  Kauf.PLF12: github://KaufHA/PLF12/kauf-plf12.yaml
esphome:
  name: ${name}
  name_add_mac_suffix: false
wifi:
  ssid: wifi_ssid
  password: wifi_password
  
# Optional manual IP
  manual_ip:
    static_ip: 192.168.1.209
    gateway: 192.168.1.254
    subnet: 255.255.255.0

I had changed the names and wanted to disable entities then add the manual IP. It seemed to flash okay, but now not online anymore. I checked the light and it is alternating between red/blue. Is there a hard reset which I can do to factory reset by holding the power button down? I tried this and it only turned off red flashing or turning on and doing the same thing red/blue - I can't find it in the phone's SSID list now.

EDIT - Rocky start - but I think I got it, held down the power button for 30 seconds, got a 2 blue pulse 1 red pulse repeating, I was then able to find the device on wifi SSID "dishwasher v (version of firmware can't recall). I could then reconnect to the Wifi and it took about 2 or 3 tries, but it finally is back online where it should be. ***

I bought a 4 pack from Amazon and dropped a fresh one on and I renamed it to dishwasher and saw that the YAML output "dishwasher' in quotes, so maybe that's where I went wrong? I'm not going to try setting a static IP until I can confirm from an authority here (Dev?) if that is what 'soft bricked' it?

I would greatly appreciate the proper formatting for this so I don't end up repeating this same mistake twice. ;)

So you got the one plug back that you were having trouble with?

Well, the issue I see with your yaml is that the wifi credentials aren't substitutions. So the plug is probably trying to connect to a wifi network called "wifi_ssid" that I'm guessing doesn't exist.

Needs to be like:

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

I got the primary plug I was having issues back by doing the reset by holding down the power button for 30 seconds. I guess it disassociated itself with the WiFi and kept the rename to "dishwasher" so when I found it in the SSID lists to connect my phone to, it was under the "dishwasher" hostname which was fine.

I think we can close this issue though it's up to you. :) I really love how your plugs work so far! Easy as pie to install in Home Assistant!
