Thermostaat is a little app that shows the current temperature and humidity. If you have a (PIR) motion sensor, it can show if there's some movement too.
clone this repo and run: npm install
You need to be root to run an application on a port under 1024 but because I didn't like the fact of running the frontend app as root we run the app on port 3000 (as usual) and forward port 80 to 3000
=> sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3000
