RaPi-Smarthome

Some private work to create a web-app that can communicate with 433 MHz devices and the Bose SoundTouch speakers.

app.js is the main backend and is handling communication to 433 MHz devices and frontend and DB related actions
wecker.js is the backend for most SoundTouch related actions such as setting an alarm and sleeptimers

Interesting

Added a BOSE SoundTouch Alarm system, as these devices are not able to do that themselves.
Added Device discovery via MDNS
Added a sleeptimer system for the BOSE SoundTouch devices
Added some responsive features to make the app work with most iOS devices

Download the latest NodeJS file with wget http://nodejs.org/dist/latest-v4.x/node-v4.4.0-linux-armv7l.tar.gz (It depends on your Raspberry PI if you need a version for ARM6, ARM7 or ARM8)
Unpack the file with tar -xvf node-v4.4.0-linux-armv7l.tar.gz
Change to the directory with cd node-v4.4.0-linux-armv7l
Copy the files to "/usr/local" with sudo cp -R * /usr/local/
Check the version & installation of NodeJS with node -v, for me it`s "v4.4.5"
Check the version & installation of NPM with npm -v, for me it`s "2.15.5"

Use the command sudo apt-get install couchdb to install CouchDB 1.4 on the Raspberry Pi (this version is quite old, but enough for our purpose)
Check the version & installation of CouchDB with couchdb -V
Try to start CouchDB with sudo couchdb, it should say something like "Apache CouchDB is running as process , time to relax."
If not present anyway, install "curl" on on the Raspberry PI with sudo apt-get install curl
Try to access CouchDB with curl on the PI via: curl -X GET http://127.0.0.1:5984, you should get a response like: {"couchdb":"Welcome","uuid":"10b710bc5d2fa2ed078edc29c30ca4c6","version":"1.4.0","vendor":{"version":"1.4.0","name":"The Apache Software Foundation"}}
CouchDB should now be working on your local machine
ADDITIONAL: If you like to be able to access your database from outside the PI (e.g. dev/test on local machine), use the following steps:
- Use sudo nano /etc/couchdb/default.ini and change [httpd] port = 5984 bind_address = 127.0.0.1 to bind_address = 0.0.0.0
- Restart CouchDB via /etc/init.d/couchdb restart, it should say something like [ ok ] Restarting couchdb (via systemctl): couchdb.service.
- Try netstat -an | grep 5984, it should say tcp 0 0 0.0.0.0:5984 0.0.0.0:* LISTEN, instead of tcp 0 0 127.0.0.1:5984 0.0.0.0:* LISTEN
- Now try to access the database on your Rascurl -xpberry PI from a local machine with curl -X GET http://<PI-IP>:5984

To use the MSDN discovery you need the Package "Development headers for the Avahi Apple Bonjour compatibility library", use sudo apt-get install libavahi-compat-libdnssd-dev

Use sudo apt-get install git to install Git on the Raspberry Pi
Use sudo npm install forever -g to install Forever (https://github.com/foreverjs/forever) on the Raspberry Pi (Keeps scripts running)

Use git clone https://github.com/DeMoehn/RaPi-Smarthome.git to clone this Git to your Raspberry Pi
Change to the repo directory with cd RaPi-Smarthome
Use sudo npm install to install all needed packages
Try node app.js and check if the application is running
Try node wecker.js and check if the timer app is running

Go to the file config.json and look for "couchDB" and then "ip": "192.168.1.220"," on line 4
Change ip": "192.168.1.220" to your couchDB IP address
In the "RaPi-Smarthome" Folder, use sudo chmod +x ./dbsetup/dbsetup.sh to make the file executable
Run ./dbsetup/dbsetup.sh and follow the installation process

To make the scrips start on reboot I use crontab, to be sure they're restart when crashing I use forever
Move the files alarm-starter.sh and app-starter.sh from the Folder startup-scripts to your root folder (where RaPi-Smarthome is located)
Make sure the scripts alarm-starter.shandapp-starter.share executable (otherwise usesudo chmod +x alarm-starter.sh&sudo chmod +x app-starter.sh`)
Use crontab -e
Now add the lines @reboot /home/pi/app-starter.sh & and @reboot /home/pi/alarm-starter.sh &
Now reboot your Raspberry Pi and see if everything works (use: sudo reboot -n)
