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 using SONOFF RF BRIDGE
|
||||
- publish MQTT data to a different topic related to received 433Mhz signal using SONOFF RF BRIDGE
|
||||
|
||||
This implementation into OpenMQTTGateway is based on Xose Pérez work ESPURNA (https://bitbucket.org/xoseperez/espurna)
