ESP8266 not receiving packets

[gbhec]

Hi all I am new to ESPHome and Home Assistant but I have been able to follow the brilliant instructions on the site - to a point. Unfortunately it seems I am not getting any response packets on the rx which show as being sent on the tx - this is the same whether in the panel or forming a loopback connection. I also tried amending the config to use pins to 12 and 14 but have the same issue.

I am using a WEMOS D1 Mini V4.0.0 ESP8266 WiFi Development Board with Type-C USB so I am not sure if there is something I am missing in the config as well as changing the MY_BOARD: "d1_mini" statement.

Any support would be greatly appreciated.

First of all I'm not that knowledgeable about ESPHome setup.
However I believe that to work with ESPHome the board has to be known about and be listed on the platforms website here
https://registry.platformio.org/platforms/platformio/espressif32/boards

I do say this in my yaml file example
https://github.com/davesmeghead/visonic/blob/master/custom_components/visonic/visonic_esphome_configuration.yaml

# For the MY_BOARD setting:
#     The list of board types can be found here: https://registry.platformio.org/platforms/platformio/espressif32/boards
#     You need the proper string e.g. "AZ-Delivery ESP-32 Dev Kit C V4" is "az-delivery-devkit-v4" so click on your board type and find the string

I've had a very quick look and all I could find is an ESP32 WEMOS D1 Mini and not an ESP8266.
On that website if you put your mouse next to the name you can copy the board id.

So I'd suggest to either try a different board, probably an ESP32, or to find an equivalent ESP8266 board on that platforms website.

Quick follow up, I realised that there is an ESP8266 platform website as well
https://registry.platformio.org/platforms/platformio/espressif8266/boards

Searching that site (change it to list 1000 items per page)

These 2 make the board id
d1_mini_lite
d1_mini_pro

You could try these

Thanks for the response. Sorry for some reason I do not have those first few lines explaining that in the yaml. I just checked the website as you suggested, and it appears to be listed with the d1 R2 Mini option being the closest match on specs: <img width="911" height="881" alt="Screenshot 2026-02-21 134958" src="https://github.com/user-attachments/assets/0f7106c9-cc91-4eb3-9c3a-59d390ab7bd5" />
