Nodemcu 4 relay. This LED can be replaced by a Relay and an AC appliance to build a Home Automation Application. I programmed the ESP to start a portal through which I can derive the relay by triggering GPIO-0 & GPIO-2. This article is a simple and easy to follow reference guide for the ESP8266 NodeMCU GPIOs. Circuit + step-by-step guide to make Tasmota NodeMCU ESP8266 Home Automation project to control 4 relays with Alexa and switches. Yet, there is a more straightforward option: a 4-channel relay module. The relay is powered by a 5V DC source, and the ESP8266 is used to switch the relay on and off via its D1 pin, allowing for remote or automated control of the AC light. Latched switches or Push buttons Circuit of the ESP8266 NodeMCU project In the circuit, I have used D1 (GPIO-5), D2 (GPIO-4), D5 (GPIO-14), and D6 (GPIO-12) GPIO pins to control the 4-channel relay module. 14 US $9.
