Remote light switch with Blynk, Node-RED and MQTT #IoT #NodeRED #MQTT
Mike Diamond’s voice-controlled lightswitches suddenly stopped working due to a security concern between Blynk, Google, and IFTTT. As a result, their significant other could no longer control their reading light.
Using an ESP8266, a push-button, and two AA batteries, they built a physical switch to replace the voice-controlled switch. They built a new NODE-RED workflow to integrate their previous workflow with the light switch.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
