My integration doesn’t use ESPHome, but esplink

Just hook it up by serial port and follow the link mentioned here.

Once the esp32 has been flashed with esplink, it will start up as a wifi hotspot, which enables you to connect it to your wifi network.

Esp-link Wifi configuration
===========================

For proper operation the end state that esp-link needs to arrive at is to have it
join your pre-existing wifi network as a pure station.
However, in order to get there esp-link will start out as an access point and you'll have
to join its network to configure it. The short version is:

 1. esp-link creates a wifi access point with an SSID of the form `ESP_012ABC` (some modules
    use a different SSID form, such as `ai-thinker-012ABC`)
 2. you join your laptop or phone to esp-link's network as a station and you configure
    esp-link wifi with your network info by pointing your browser at `http://192.168.4.1/`
 3. you set a hostname for esp-link on the "home" page, or leave the default ("esp-link")
 4. esp-link starts to connect to your network while continuing to also be an access point
    ("AP+STA"), the esp-link may show up with a `${hostname}.local` hostname
    (depends on your DHCP/DNS config)
 4. esp-link succeeds in connecting and shuts down its own access point after 15 seconds,
    you reconnect your laptop/phone to your normal network and access esp-link via its hostname
    or IP address

After it is connected, you can set the correct pins
assignments (in your casr TXDO and RXDO)

Here some info on how I set it up on my esp01 module:

Unfortunately, then I get this.

maybe this will work

I’ll just give it a try, thanks for your help

Yes, it works.

Great you got it working…

And yes, you were correct ESP-Link doesn’t work on ESP32; it is ESP8266 only.

But…if every you want to try again, you can use this on ESP32:

For me it wasn’t very stable; but that was probably because the ESP8266 isn’t powerfull enough (the ESP32 is a lot better in that way)
