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 KeyCode derived from GPIO Input
|
|
|
|
This reads up to 4 gpio with latch signal (gpio line) and combines the bits as KeyKode - can be connected
|
|
to EV1527 receiver.
