I’ve been diving into the world of Zigbee lately, and while it’s been a fantastic journey, I’ve hit a bit of a snag. After moving my Home Assistant setup to a different VLAN to get my Google Home integration working, I noticed something odd—my Zigbee network started crashing every few minutes. 
Let me walk you through what I’ve experienced and what I’ve tried so far:
The Problem
After the move, I started seeing these error logs in my Zigbee2MQTT setup:
[2025-07-14 19:25:30] error: zh:ember:uart:ash: Received frame with CRC error
[2025-07-14 19:26:04] error: zh:ember:ezsp: ERROR Transaction failure; status=ASH_ERROR_TIMEOUTS
And it just keeps happening, which is pretty frustrating because I’ve got 32 Zigbee devices that rely on this setup!
What I’ve Tried
- USB Port Changes: I moved the Zigbee stick to different USB ports, used a powered USB hub, and even tried a direct connection. No luck!
- Firmware Updates: I updated the firmware on the stick, but it didn’t make a difference.
- Power Cycles: I restarted everything—my router, the Zigbee stick, and even the host machine. Still nothing.
- Log Analysis: I’ve poured over the logs, and it seems like communication timeouts and CRC errors are the main culprits.
Thoughts and Next Steps
- Interference Check: I’m wondering if there’s some wireless interference now that I’m on a different network. Maybe moving the Zigbee stick closer to the router or away from other devices could help?
- Reset Network: I’m considering resetting the Zigbee network entirely. It’s a bit scary because I’d have to re-pair all my devices, but maybe that’s the only way to get a fresh start.
- Alternative Firmware: I’ve heard about different firmware versions for Zigbee sticks. Maybe trying a different one could stabilize things?
