Security System
In my smart home automation system I've built a security system with the node-red build in nodes, it works but I wanted to simplify the flow + subflow. Here is a solution based on the dynamic state machine:
- start or set all dsm's
- arm the security system
- try the sensor input simulation (magnet contact, button click)
- try disarm, reset
