OHS is open Arduino based burglar alarm and automation platform. It can work as new alarm gateway, or it can replace your old alarm panel. OHS can use any wired 12V sensor, PIR, smoke or reed switch. It has Web interface that is used to set it up. OHS has GSM modem that is able to send SMS or page you. It has radio interface for environmental sensors. OHS is self-contained, it does not need any cloud service, only optional SMTP server for emails, or MQTT to publish collected sensor data.
There is small update to code for mainboard. I have added to global setup user and password prompts to allow user do basic authentication. The function is derived from Webduino functionality, and secure all pages provided by system. I guess the added security is fine on home networks, and no one should allow outside world to connect to your private security interface. New code has been pushed to GitHub.
