433toMQTTto433 - ESP8266 program for home automation
|
||||
|
||||
Act as a wifi gateway between your nodes and a MQTT broker
|
||||
Send and receiving command by MQTT
|
||||
|
||||
This program enables to:
|
||||
- receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data
|
||||
- publish MQTT data to a different topic related to received 433Mhz signal
