Washing Machine App

Installation

Requires git, python3
- curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
- python get-pip.py --user
- pip install --user pipenv
Clone repository: git clone https://github.com/M4a1x/laundrymeter
Enter directory: cd laundrymeter
Install dependencies: pipenv install
Run ./start_development.sh or ./start_production.sh

To run the server on port 80 (or other port < 1024)

Change the script accordingly (i.e. substitute 8000 with 80)
Install authbind (as root)
i.e. add all users to be able to use port 80: touch /etc/authbind/byport/80 and chmod 777 /etc/authbind/byport/80 (also as root)
Start the script: authbind --deep start_production.sh

To be able to logout from ssh after starting the server

Use nohup authbind --deep sh start_production.sh &
or tmux / screen

Configuration

VM IP: 100.117.66.20
Needs the following connections:
- TP-Link Smartplug (for sensor readout), in 192.168.22.3
- LDAP-Server, SSL-Port 192.168.21.10:636, for authentication
- Port 587 to connect to gmail via STARTTLS, to send notifications
- Port 8000 for unencrypted access to REST Api. Reverse proxy for https is recommended.

Washing Machine Stats

Closed door, not running, but on: 2.2W, current: 33mA
Open door, not running, but on: 0W, current: 42mA
Off: 0W, 42mA
Finished: < 50W distinct pattern, sharp spikes with pauses
Heating: > 2000W Temperature can probably be infered from duration

Running Detection

Problem

Machine pauses after heatup. 3min, 2min
- -> Threshold of 50W, delay of 4min (48 ticks)

Other ideas:

Simple Threshold
Signal Energy, AKF
Double Threshold
Timed Threshold
