OpenMQTTGateway - 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
|
|
|
|
This gateway enables to:
|
|
- receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data based on ESPilight library
|
|
- publish MQTT data to a different topic related to received 433Mhz signal based on ESPilight library
|
|
