I'm using some ESP8266 "D1 mini" modules, mostly for retrocomputing :)

I've built one that acts as a WiFi modem, it uses the "esp_modem" firmware  
that I've changed slightly to fit my needs. It emulates a modem (so it  
understands AT commands) and is connected to one of my RC2014 Z80  
computers running CP/M and a terminal program.

Another nice option is the "ESPterm" firmware, it acts as a terminal: It  
features a webserver that you can connect to via a webbrowser. On this  
webpage, you then see a "terminal window" that is talking via the serial  
port of the ESP8266 to the attached machine, eg. a Z80 CP/M computer :)

And I'm experimenting (I guess, the next time slot for this is during the  
christmas holiday period) with an "IR blaster" firmware, so that I can  
attach an IR diode and IR receiver to the ESP8266 and then can receive and  
send IR codes to control (in my case:) a ceiling light that normally uses  
an IR remote control. (So I can integrate it into HomeAssistant *g*).

The biggest project I'm a little part of is the "VT132" terminal module  
for RC2014 compatible computers. It uses an ESP32 to feature a VT100- 
compatible terminal (with VGA and PS/2 or USB connectors) and also a WiFi  
modem. I'm part of the beta testing team and this is a really nice module  
for my CP/M machines, to make them stand-alone computers :)

So, I'm not that much into real developing of software/firmware for the  
ESPs, but more into using and tweaking existing software :)

Greetings from Germany,
Anna
