# Spacebucket
Building a fully automated spacebucket using a Raspberry Pi 2 and Raspberry Pi Zero W.
Have a look at the [wiki](https://github.com/NilsDeckert/Spacebucket/wiki) for a more detailed insight into the idea
For this project I'm using two Raspberry Pis, a Zero W (publisher) to capture sensor data and to pass it to the Pi 2 (subscriber). The Raspberry Pi 2 then processes the received data, controls fans and light accordingly and uploads the data to a database for later use (e.g. visualizing it in a graph).

# Getting started
**Note: As of right now, the following part is not complete by any means and will be updated every now and then. How ever, I am listing useful ressources I used in the wiki for anyone who wants to try or has a similar project. Cheers!**
## Prerequisites / Setup
---
## Publisher:
#### Temperature and humidity sensor:
The DHT11-sensor uses the **Adafruit_Python_DHT** library. To use it you have to install the python-dev module first:
```shell
sudo apt-get install build-essential python-dev
```
then download the library and install it
```shell
git clone https://github.com/adafruit/Adafruit_Python_DHT.git
cd Adafruit_Python_DHT/
sudo python setup.py install
```
#### mqtt:
```shell
sudo pip3 install paho-mqtt
```
#### MySQL:
```shell
python3 -m pip install mysql-connector
```
---
## Subscriber:
#### 433MHz transmitter
To use the 433MHz transmitter install [433Utils by Ninjablocks](https://github.com/ninjablocks/433Utils):
```shell
git clone --recursive https://github.com/ninjablocks/433Utils.git
cd 433Utils/RPi_utils
make all
```
and then compile the outlet.cpp:
```shell
cd ../../
sudo g++ -DRPI /433Utils/rc-switch/RCSwitch.cpp outlet.cpp -o outlet -lwiringPi
```
#### mqtt:
```shell
sudo pip3 install paho-mqtt
```
#### MySQL:
```shell
python3 -m pip install mysql-connector
```
### Files on the publisher:
* mqtt_publisher.py
* pw.py
### Files on the subscriber:
* mqtt_subscriber.py
* outlet.cpp
* emailinfo.py
* pw.py
### pw.py
Change the `pw.py` on both devices to fit your database
## Usage
If you've set up the software and the hardware correctly, start the software on both devices:
### Subscriber:
```shell
sudo python3 mqtt_subscriber.py
```
### Publisher:
```shell
sudo python3 mqtt_publisher.py
```
### Command line arguments:
When starting the scripts you can use command line arguments:
```
sudo python3 mqtt_subscriber.py -h
```
```
usage: mqtt_subscriber.py [-h] [-d]
optional arguments:
-h, --help show this help message and exit
-d, --debug Toggle debug output
```
### Commands:
With the publisher program running, you can also use commands to interven in the program:
To list all available commands type:
```
help
```
To read the current sensor data and send it to the subscriber, use
```
force measure
```
The cycle in which the software measures the data will not be shifted by this
You can manually adjust the fanspeed using:
```
fanspeed
```
followed by a number between 0 and 1000 in the next line.
With debug mode enabled, you can use
```
simulate temperature
```
and
```
simulate humidity
```
followed by a number of choice to simulate the corresponding value and send it to the subscriber
