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.
I've been a little busy at work and with family recently. This led into
an unintended testing period of the software and hardware. I'm happy to
say that the system is working now for 25 day without any problems.
Groups, zones, sensors are doing what they should. The communication
with wired and wireless modules is working. GSM modem is sending SMS,
LAN is responding and sending data through MQTT. All is just working.
Big success for me!
This brings me to an idea, does anyone want
to have PCB for this project? Let me know, I have some spare ones, and
will send them to you for 6-8 EUR (10$), depending on your location.
