IntertechnoGateway

Use OOK 443 MHz sender (like FS1000A) to send Intertechno commands initiated by mqtt requests or via web page

Circuit

ESP32	FS1000A
VCC*	VCC
GND	GND
IO16**	DATA

*) 3.3V will, work, but with reduced range
**) most GPIO pins will work, just define PIN_DATA

Build

Prerequisite

• PlatformIO (e.g. as VS Code extension or standalone)
• ESP32 (any with AsyncWebserver support)

Usage

• Edit platformio.ini:
  • change upload and monitor ports to where the ESP is plugged in
  • change default env to what matches your ESP best
• Start build and upload

  pio run --target buildfs
  pio run --target uploadfs
  pio run --target upload
  

• Optional: check serial output to see what's going on on the ESP

  pio device monitor
  

• Connect to AP intertechnogateway-1 and configure wifi via http://192.168.4.1
• Open http://intertechnogateway-1 in a browser
• or publish on mqtt topic intertechnogateway/1/cmd
  • payload has 3 characters:
    1. family (0-f)
    2. device (0-f)
    3. off or on (0 or 1)

Other

• Uses Bootstrap (5.2.3) for flexible layout (served as local files. Size: ~60k)
• Uses JQuery (3.6.1) (Size: ~30k)
• Uses base64 encoded favicon converted by https://www.base64-image.de/ (Size: ~300 bytes)
• Uses Preferences lib to store current family and device for the web page
• Optional: the ESP will contact ntp, syslog and mqtt broker. See platformio.ini for configuration.
