Your Philips Hue
Zigbee network becomes unstable during Z-Wave network healing because both
protocols generate high RF traffic and may overlap in the 2.4 GHz band,
causing interference. Additionally, Z-Wave healing can create temporary routing
congestion that affects nearby Zigbee coordinators. Adjusting channel
allocation, distancing hubs, and limiting simultaneous mesh rebuilds typically
resolves the issue.
Preliminary
Diagnostic Steps
Before applying any
fix, run these technical diagnostic checks to confirm the cause of the
instability:
1. Check Zigbee
Channel Overlap
Verify that your Hue
Bridge Zigbee channel (usually 11, 15, 20, or 25) does not overlap with your
Wi-Fi or Z-Wave activity. Use a Wi-Fi analyzer to inspect 2.4 GHz congestion.
2. Review Z-Wave
Heal Logs
On your Aeotec or
Z-Wave JS interface, inspect logs during the network heal process. Look
for spikes in routing attempts, failed node responses, or dense packet
retransmissions.
3. Measure RSSI
& LQI on Zigbee Devices
In Home Assistant →
Zigbee integration → Device info, observe sudden drops in Link Quality (LQI)
or rising RSSI noise levels during Z-Wave healing.
4. Check Physical
Placement
Ensure your Hue Bridge
and Z-Wave hub are not positioned within 1 meter of each other, as RF
interference increases dramatically at close distances.
5. Inspect Router
Activity
If using a Wi-Fi 6/6E
router near both hubs, check whether beamforming or transmit power
boosts occur during the mesh rebuild.
Step-by-Step
Technical Fix
Follow these precise
technical actions to stabilize your Zigbee network:
1. Change the
Zigbee Channel
If your Hue Bridge
uses channel 20 or 25, switch to channel 15 or 11 to reduce Channel Overlap
with Wi-Fi.
Steps: Hue App → Settings → Zigbee Channel Change.
2. Schedule Z-Wave
Network Heals Manually
Disable automatic
healing and run it during low-traffic hours.
Home Assistant → Z-Wave JS → Settings → Disable nightly heal.
3. Increase
Physical Separation
Move your hubs at
least 1–2 meters apart to minimize RF saturation in the 2.4 GHz band.
4. Reduce Power on
Zigbee Router Devices
Some bulbs default to
maximum transmit power. Lower power levels can reduce interference.
Zigbee2MQTT → Devices → Power Settings.
5. Update Firmware
on Both Hubs
Install the latest
firmware on your Hue Bridge and Aeotec Hub to improve Mesh Network Health
and radio coexistence algorithms.
6. Reduce Z-Wave
Polling Frequency
Polling overload can
saturate the airwaves.
Home Assistant → Z-Wave JS → Node → Reduce polling interval to 30–60 seconds.
7. Enable Static
Routing in Z-Wave
Assign manual routes
for frequently used nodes to reduce traffic during heal sessions.
Preventing
Future Conflict
1. Assign Static IP
Addresses
Set Static IP
for both Hue Bridge and Aeotec Hub to avoid routing delays across your LAN.
2. Use a Dedicated
IoT Wi-Fi SSID
Separating your IoT
devices reduces multicast storms that may affect Zigbee’s performance.
3. Set Up a RF-Free
Buffer Zone
Keep all hubs,
repeaters, and bridges at least 1–2 meters apart to avoid RF noise overlap.
4. Reduce Network
Heal Frequency
Run Z-Wave healing
only when adding/removing devices—not daily.
5. Maintain
Balanced Mesh Density
Avoid overloading one
mesh (Zigbee or Z-Wave) with too many repeating devices in the same location.
