I’m new to this but making good progress. Acquired the DigiXstick yesterday and getting good ZigBee connections across my RaspberryPi 4 throughout the house. I played with the ufw firewall and found pretty quickly I could break the service connection by over-constraining a firewall. Any suggestions for firewall settings that minimize risk while still allowing functionality?
For background, I intend to use this system for basic home security, water leak detection and controlling the timing of my hot water re-circulation pump. Additionally I’ll be monitoring connected smoke alarms and triggering their “unbearable whine” via the Rpi GPIO when an intruder enters the abode. Initial efforts make me very optimistic this will work.
Any suggestions/input would be appreciated.
