* factoring of the publishing function * integration of json publishing to MQTT * receiving and transcode json messages from mqtt * replace the TRACE runtime condition by a buildtime one so as to decrease program size * remove retainFlag parameter not necessary for the moment * Increase the scope of tests for arduino mega and esp32 * Update arduinojson library to 5.13.3 * add macros to choose between simple or json publishing or both * differentiate build test for ATmega2560 * correct wrong sprintf definition * change IDE version for continuous integration * let default warning level in arduino ide * correct pins for ESP32 * reorganize user_config

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.
