arduino_access_control

• Use arduino to control access to electrically actuated devices

Components

• Electronically actuated device (garage door/door/or anything you want to access)
• WiFi in range
• Arduino as node/client (communicates to network using ESP8266 and WIFIESP arduino lib)
• Arduino runs this MQTT lib
• A master/server that runs mosquitto and a webserver

How it works

1. Pincode gets sent to topic for door requests (either by pinpad, mqttclient, web interface, rfid device etc)
2. Pincode checked against database of allowed users
3. Response is sent to the node (allow or deny)
4. Relay is actuated and DB is updated

User managment

Users added, modified and deleted via webpage in webserver (https://<servername/URL>)

Maintenace

Initial setup

• Update doorsetup.py to reflect doors you want to control
• run python views.py <admin username> <admin password> You get to choose what they are!
• Stop script then run via systemd (or whaterever process manager you use)
• Populate db via web interface (login usng credentials supplied above above)

ssl certs

Letsencrypt cert needs to be renewed periodically:

1. Open port 80 on router to webserver (need to enable ipv6 for fritzbox to allow this then disable as ISP falls apart with IPv6 used)
2. run sudo certbot renew
3. Disable access via port 80

Troubleshooting

My uwsgi won't work (upstream timeout errors in /var/log/nginx/error.log)

• # systemclt stop door
• running (from python dir) $ uwsgi --ini uwsgi.py
• Ctrl+C that process after testing api is delivering
• # systemctl start door This seems to work
