Hello everyone,
I'm a beginner and I've been struggling for over 6 hours to get my Zigbee network stable. I have a problem that I can't solve, and I might be missing something fundamental.
My Setup:
- Dongle: Sonoff Zigbee 3.0 USB Dongle Plus V2 (Model E).
- Connection: Connected via a USB extension cable.
- Environment: Small apartment (28 sqm).
- System: Home Assistant OS with ZHA integration.
- Wi-Fi: 2.4GHz channels are configured to avoid interference.
The Problem: I have a motion sensor and a light switch in the bathroom.
- In the Home Assistant UI, I can see the sensor state changing (it correctly shows "Detected" when there is motion).
- However, the automation often fails to turn on the light. It works for a few minutes after a reboot, then stops, even though the sensor status is still updating in HA.
Firmware Issue: I tried to update the dongle firmware using the "Silicon Labs Flasher" add-on (v0.5.0), but:
- The logs say:
WARNING: No firmware found for the selected device, assuming firmware is installed. - If I try to manually add
firmware_version: "7.4.3.0"in the add-on configuration, the system automatically deletes this line as soon as I click "Save". I cannot force the update.
What I've tried:
- Re-paired devices multiple times.
- Moved the dongle away from the server using a cable.
- Checked and fixed Wi-Fi channels.
- Re-enabled ZHA after it accidentally got disabled.
Why does Home Assistant see the motion, but the light doesn't respond? Is this a firmware issue with the V2 dongle, or a bug in the Flasher add-on that doesn't allow manual overrides?
Please help, I'm completely stuck!
