Smarthome App

Central heating system and other tools.

Recent changes:

• This repository has now been succeded (sort of) by OpenCentralHeating which focuses just on the central heating features.

Installation:

My setup involves 3 physical machines, a Raspberry Pi 3B, running Ubuntu Server 20.04, as the main server connected to the relay that controls the central heating, a NodeMCU ESP8266 microcontroller running MicroPython that acts as a temperature sensor and serves JSON data, and a separate Raspberry Pi Zero W, running Raspian Lite, as a security camera.

-Full write-up of initial build-

Main server

1. Clone the repository
2. Install requirements: pip install -r requirements.txt
3. run server with uvicorn, eg. uvicorn server:app

N.B. Music over bluetooth (mpv) functionality currently in development. Additional requirement: sudo apt install libmpv-dev or similar depending on your distro.

Temperature sensor (old instructions for Raspberry Pi)

1. copy temp_api.py and network_check.sh to the temperature sensor machine (in my case, the Pi Zero W) and set the SENSOR_IP in heating.py on the main machine to the local IP of this machine.
2. set up BME280 or similar temperature sensor module with GPIO pins according to pins used in temp_api.py (or adjust code to reflect pins you use)
3. pip3 install flask
4. make network_check.sh executable (chmod +x) and add to your cron tab to run every few hours (this will solve the problem of your Pi Zero W shutting off wi-fi to save power, you should also disable power saving in the pi's wi-fi settings, but this was not a complete fix for me, hence the shell script.)
