ESP8266 based bidirectional bridge between MQTT and IR (change MQTT message to IR signal and change received IR signal to MQTT message)
ESP8266 based gateway between MQTT and IR. Code compatible with PlatformIO. Works with ESP-01 (debug mode have to be disabled in globals.h)
GPIO WEMOS | GPIO ESP01 | Usage |
---|---|---|
13 | 0 | IR receiver |
14 | 3 (Uart RX) | IR LED - connected via simple transistor amplifier |
15 (to +3,3V) | 2 (to GND) | Button - used for reset configuration |
2 (Wemos buildin) | not used | LED |
For ESP01 following changes have to take place:
In VS Code press F1 enter ''git: clone'' + Enter and insert link to my repository (https://github.com/piotrC4/mqtt-ir-transceiver)
Edit platformio.ini and setup upload_port variable acording to system settings if PlatofmIO can'd identify proper COM port
In PlatformIO menu choose PROJECT TASKS -> Build
Connect ESP to PC via serial adapter. In PlatformIO menu choose option PROJECT TASKS -> Upload.
During first boot device will act as AP with SSID IRTRANS-XXXXXXXX (password is XXXXXXXX). Connect to this AP and go to http://192.168.4.1. Configure WIFI and MQTT paramters.
If during boot device have is pressed, device will go to configuration mode.
