Homewhiz integration + Bluetooth via ESPHome BT Proxy + Beko washing machine

I used to have this working, but my ESP32 device was unstable som I upgraded it to one newer. In the meantime something has happened, and now I cannot by any means get HA to connect with it.

The Beko washing machine connects fine using BT and the Homewhiz app on my phone.

The Beko washing machine is discovered using BT Proxy, but all the messages contain connectable: false.

A typical message dump from the washing machine in BT Proxy:

{"name":"HwZ_fb053c2749002bxxxx","address":"xx:xx:xx:xx:xx:xx","rssi":-58,"manufacturer_data":{},"service_data":{},"service_uuids":[],"source":"xx:xx:xx:xx:xx:xx","connectable":false,"time":1750179944.5011907,"tx_power":null}

My BT Proxy config:

  friendly_name: esp32-btproxy

  board: esp32-s3-devkitc-1

When installing the Homewhiz integration, I am asked to use my Homewhiz credentials, and it seems like it tries to use whatever data it retrieves from Homewhiz to connect with the washing machine, but so far no success.

Does anyone have a step-by-step guide that might help me get it back in HA?

I added our Beko the HomeWhiz and ESP Proxy with Webpage/UI only without any manual yaml writing and it worked out of the box:

  1. installed home-assistant-HomeWhiz as described using Option 1. Using HACS as described.
  2. Installed ESPHome Bluetooth proxy via WebPage (flashed via Webpage).
  3. After that, HA offered me to integrate both BT devices, Beko & ESPHome Proxy (wants the Wifi credentials)

I have not made any other manual configurations.
