doorstate-rs

A rewrite with a few more features of this.

Modify our hackspace's door state with a Raspberry Pi and a ridiculously oversized switch. This script writes the spaceapi.json and Site.SiteNav files for the Space API and PmWiki. These files are mounted via sshfs.

Installation instructions

Make sure the root user is able to log in the remote machine by having the ~/.ssh folder prepared. Furthermore, modify the /etc/fstab file to use sshfs as documented here.

Optional, requires feature gpio-support: Connect the switch to a gpio pin and a ground pin. Set this pin as parameter -s PINNUMBER in the environment file (doorstate-rs).

# Install required software
# (Probably only pigpio)
# and have rust installed

# Clone this repository and cd into it
git clone https://github.com/hackspace-marburg/doorstate-rs.git
cd doorstate-rs
sudo cp doorstate-rs.service /etc/systemd/system/

# Drop --features gpio-support if not in use on an Rasberry Pi.
cargo build --features gpio-support --release


sudo mkdir /etc/conf.d/
sudo cp doorstate-rs /etc/conf.d/
# Modify /etc/conf.d/doorstate-rs afterwards

sudo systemctl daemon-reload
sudo systemctl enable doorstate-rs.service
sudo systemctl start doorstate-rs.service

Build instructions

To get a server side service which recieves MQTT messages and changes the spaceapi as well as the door state on the hsmr homepage you can simply

cargo build --release

If you require support for Raspberry Pi GPIO to attach a hardware door switch to it you'll need to:

cargo build --features gpio-support --release

Sadly all this is in dependency hell, as the used mqtt library itself had a ton of dependencies.
