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.

W5500 test PCB progress

PCB arrived on Monday and Tuesday I put it together. Say it short, it works. Happy again, I can continue with testing of new gateway. The differential pairs design worked, and the 33R dumping resistors are not required. Moving 3V3 power line out of RX and TX pairs probably also. Results is having a nice 2,5x5 cm breadboard friendly W5500 board. I will put PCB and finished version also to BUY section on right side. Maybe someone is interested.
