Setup:
- Home Assistant with Z-Wave JS UI
- Recently upgraded to ZWA-2 Z-Wave controller
- Existing Ring security system with Z-Wave door/window sensors
- Previous Controller - Aeotec Z-Stick 7
Problem: After switching to the ZWA-2, my Ring Z-Wave devices began experiencing significant issues:
- Door/window sensors frequently dropping from Ring network
- Sensors showing as “unavailable”
- Missed events (doors reporting closed when actually open)
- Issues began immediately after ZWA-2 installation
Troubleshooting Attempted:
- Waited 1 week for automatic route optimization
- Restarted all Z-Wave devices and services
- Problem persisted throughout testing period
- Reverted to previous controller → Ring system returned to normal operation
Technical Questions:
- Has anyone experienced similar interference between ZWA-2 and other Z-Wave networks?
- Are there configuration settings in Z-Wave JS UI to reduce transmission power or adjust interference mitigation?
Suspected Cause: The ZWA-2 may be transmitting at higher power levels, potentially interfering with the Ring network’s mesh topology or causing communication conflicts.
Looking for:
- Similar experiences with ZWA-2 and multi-network Z-Wave setups
- Recommended configuration changes
- Alternative solutions to run both networks simultaneously
My planned next steps are to separate the two controllers. Today, they are a shelf apart in my home-lab.
Any insights would be greatly appreciated! Thanks.
