I have 3 projects in everyday use around the house that are based ESP8266 Basic. It is great that I can just log in to my device make some changes and not have to worry about recompiling and reflashing the firmware every time I want to change something simple.
1. A simple lamp relay that I can control with Amazon Alexa or on board web interface
2. A clock with time date and temperature based on a 2 line cash register POS display
3. A centrally located multi relay controller that turns various stuff on and off interfaces with local wall mounted push buttons. It interfaces with Amazon Alexa as it's own local web interface. I am working to extend this to control a pool pump relay and include some on/off scheduling as well.
