TPH forecast with Raspberry Pi and AI.¶
Welcome to TPH forecast with Raspberry Pi and AI’s documentation!
about¶
This project aim at forecasting temperature, pressure and humidity(TPH). And controling air-conditioner. Home-automation with AI on Raspberry Pi and RIp TPH Monitor.
This is integrated your home automation, controling air-conditioner with AI and another infrared controlled devices such as television set or celling light and so on.
TPH forecast with Raspberry Pi and AI.¶
I explain first boot your Raspberry Pi and set up Python environment for developing.
This project is developing now, yet not finish.
Preparing¶
Please get somethings next list.
Raspberry Pi 3B, 3B+
micro SD card, 16GB above(recommended)
USB connected key board
USB connected mouse
HDMI cable and display
use TV instead of display
Python development environment
We supported only Python 3.7 upper version.
Set up Raspberry Pi¶
You must set up your Raspberry Pi.
On your Mac or PC(Linux, MS-Windows), you can install Raspbian to microSD card.
Download newest Raspbian¶
I recommend using official Raspbian which can download from Raspberry Pi Downloads.
You will choose “Raspbian Buster with desktop and recommended software” or “Raspbian Buster with desktop”.
Installing operating system image¶
You must read installation guide for installing operating system image.
And download balenaEtcher.
macOS¶
If you use Apple Mac, you can install via brew.
$ brew cask install balenaetcher
First boot¶
Only first boot time, You must connect USB keyboard, USB mouse, and monitor via HDMI. You must set Wi-Fi network and enable SSH via raspbian-config. Please set fixed IP address, for example 192.168.0.121/24.
Test remote connect¶
On your Mac or PC, remote connecting test via ssh.
$ ssh pi@192.168.0.121
Package upgrade¶
I recommend upgrade your Raspbian.
$ sudo apt update
...
$ sudo apt upgrade
Prepare development environment¶
You can development on your Raspberry Pi.
I recommend preparing development environment on your Mac or PC.
pyenv and pyenv-virtualenv¶
Please install
macOS, Linux¶
Install Python via PyEnv
$ pyenv install 3.8.0
And setup pyenv-virtualenv

MS-Windows¶
If you use MS-Windows, venv instead of pyenv.
Hydrogen¶
Hydrogen is an interactive coding environment that supports Python, R, JavaScript and other Jupyter kernels.
$ python -m ipykernel install --user --name=dj3rpi380 --display-name=dj3rpi380
If you multiple pyenv versions, you may repeat this command.
List your ipkernel.
$ jupyter kernelspec list
Let’s begin development “Home automation application”.

Using SCSS/SASS¶
static/bootstrap.$ cp -r your/bootstrap-4.x.x/scss/* tph/static/bootstrap
Install some Python modules.
pip install django_compressor
pip install django-libsass
Background tasks¶
pip install django-background-tasks.pip install django-background-tasks
Registration background tasks and execute
First step¶
Create your Django Project.
mkdir django-rpi-tph-monitor
cd django-rpi-tph-monitor
django-admin startproject tph
cd tph
python manage.py runserver
Access http://localhost:8000/ on your browser. 
For access from remote computer to Raspberry Pi, on your Raspberry Pi:
python manage.py runserver 192.168.xxx.xxx:8000
You have to get another shell(terminal). Second registration task.
$ curl -X GET http://localhost:8000/monitor/tasks/5/30
Third run process tasks.
$ ./manage.py process_tasks
You can check tasks from your database that default is db.sqlite3. See background_task, background_task_completed_tasks, or monitor_bme280 tables.
