OpenMQTTGateway Addon - ESP8266 or Arduino program for home automation
|
|
Act as a wifi or ethernet gateway between your 433mhz/infrared IR signal and a MQTT broker
|
|
Send and receiving command by MQTT
|
|
|
|
GPIO Input derived from HC SR-501 reading Addon and https://www.arduino.cc/en/Tutorial/Debounce
|
|
|
|
This reads a high (open) or low (closed) through a circuit (switch, float sensor, etc.) connected to ground.
