433 MHz Fan MQTT (HomeKit) Server

This is similar to the 433 Mhz Light Server but with signals that are just recorded and replayed.

Uses:

• rpitx + rtl-sdr for capturing the signal and writing it to an iq file
• rpitx for transmitting the captured signal

Capturing

./rtlmenu.sh from rpitx folder. Place these recordings in the fan-recordings folder and match them up to the action you want to perform in the server index.js

Docker

Web server is run in docker, though to increase reliability of rpitx, the /boot/config.txt will need to be modified outside of docker

The docker image is hosted on docker hub, but this is my specific version with specific recordings. If there is a demand for it, this can be refactored to reflect a more generic version

This repo includes a workflow to build it and push it to docker hub. I would recommend changing the settings to match your info as this makes building the image much easier

Raspberry Pi Modification

Set the GPU frequency as done in the install.sh
