Open home security - your Arduino burglar alarm

OHS is open source 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 server to publish collected sensor data.

Arduino IDE upgrade

I have just updated instruction in Compiling section on right. This include complete setup of latest Arduino IDE and its environment to compile your own version of gateway firmware.

The move from 1.6.9 to 1.8.5 resulted to around 3KB smaller flash size, but on the other hand increased around 100B in RAM size. RAM size increase might be just result of different calculation of unused stack above NilRTOS environment.
