Argon Industria V5 Zigbee Module Setup
This guide covers setting up the Argon Industria V5 Zigbee Module with EAS Station™.
Hardware Overview
| Spec | Value |
|---|---|
| Zigbee Chip | CC2652P |
| USB Bridge | Silicon Labs CP210x |
| Zigbee Standard | Zigbee 3.0 |
| Device Path | /dev/ttyUSB0 |
| Baud Rate | 115200 |
| Case | Argon ONE V5 (Pi 5 only) |
The Zigbee module installs inside the Argon ONE V5 enclosure and connects to the Raspberry Pi 5 via an internal USB hub. It does not use the GPIO header or the UART pins — it's entirely USB-based.
Step 1 — Raspberry Pi 5 Boot Configuration
The Argon ONE V5's internal USB hub is not powered by default on Raspberry Pi 5.
You must add two lines to /boot/firmware/config.txt under the [all] section:
[all]
dtoverlay=dwc2,dr_mode=host
usb_max_current_enable=1
Important: These lines must be under
[all]. Anything placed under[cm4]or[pi5]is ignored on Pi 5 and the Zigbee module will not appear.
After editing config.txt, reboot:
sudo reboot
Step 2 — Install Argon Utilities
The Argon daemon manages fan control and powers up the internal USB hub on boot:
curl https://download.argon40.com/argon1v5.sh | bash
sudo systemctl enable --now argononed.service
Reboot again after installation:
sudo reboot
Step 3 — Verify the Device Appears
After rebooting, confirm the Zigbee coordinator is detected:
# Should list a Silicon Labs CP210x device
lsusb | grep -i "silicon"
# Should show /dev/ttyUSB0
ls -l /dev/ttyUSB*
Expected output:
Bus 001 Device 003: ID 10c4:ea60 Silicon Labs CP210x UART Bridge
crw-rw---- 1 root dialout 188, 0 ... /dev/ttyUSB0
If /dev/ttyUSB0 does not appear, check:
config.txtedits are under[all](not[cm4])- Argon daemon is running:
systemctl status argononed.service - The Zigbee module is fully seated in its connector inside the case
Step 4 — Configure EAS Station™
Add User to dialout Group
The eas-station service user must be in the dialout group to access serial ports:
sudo usermod -aG dialout eas-station
Configure Zigbee in the Web UI
- Navigate to Admin → Hardware Settings → Zigbee tab
- Check Enable Zigbee Coordinator
- Set Port to
/dev/ttyUSB0 - Set Baud Rate to
115200 - Leave Channel at
15(good default, avoid channels 11/25/26 to minimize Wi-Fi 2.4GHz interference) - Leave PAN ID at
0x1A62(or choose any unique hex value) - Click Save Changes
- Restart the hardware service when prompted
Verify in EAS Station™
- Navigate to Admin → Zigbee to view the coordinator status page
- The coordinator status should show
configuredwith your port settings - Check Logs → Hardware Service for:
✅ Zigbee coordinator configured on /dev/ttyUSB0 (channel 15, PAN ID 0x1A62)
Troubleshooting
/dev/ttyUSB0 not appearing
| Symptom | Cause | Fix |
|---|---|---|
No /dev/ttyUSB* devices |
USB hub not powered | Add dtoverlay=dwc2,dr_mode=host to config.txt under [all] |
| USB hub present but no CP210x | Module not seated | Check physical connector inside the case |
| Device appears then disappears | Power issue | Add usb_max_current_enable=1 to config.txt |
Permission denied on /dev/ttyUSB0
# Add user to dialout group
sudo usermod -aG dialout eas-station
# Restart hardware service
sudo systemctl restart eas-station-hardware.target
Zigbee status shows "port_open_failed"
Another process may be holding the port open. Check:
# Find what is using the port
sudo fuser /dev/ttyUSB0
# Check if another service (e.g. VFD) is using ttyUSB0
sudo systemctl status eas-station-hardware.target
If the VFD display is also configured to use /dev/ttyUSB0, move one device
to a different port or use a USB hub to assign stable device paths.
Zigbee coordinator shows as disabled in the UI
Zigbee is disabled by default. Enable it at Admin → Hardware Settings → Zigbee.
Checking hardware service logs
sudo journalctl -u eas-station-hardware.target -f
Look for:
✅ Zigbee coordinator configured— working⚠️ Zigbee serial port /dev/ttyUSB0 does not exist— USB not detectedZigbee serial port exists but cannot be opened— permission issue
Channel Selection Guide
The Zigbee radio operates in the 2.4 GHz band, the same as Wi-Fi. Choosing a channel that avoids Wi-Fi overlap reduces interference:
| Zigbee Channel | Frequency | Wi-Fi Overlap |
|---|---|---|
| 11 | 2405 MHz | Wi-Fi ch 1 — avoid |
| 15 | 2425 MHz | Between ch 1 and 6 — good |
| 20 | 2450 MHz | Wi-Fi ch 6 — avoid |
| 25 | 2475 MHz | Near Wi-Fi ch 11 — use with care |
| 26 | 2480 MHz | Wi-Fi ch 11 — avoid |
Recommended: Channel 15 or 20 in most home/office environments.
Hardware Compatibility Notes
The Argon Industria V5 Zigbee module is only compatible with Argon ONE V5 (Pi 5). It does not fit into earlier Argon cases (ONE V2, ONE M.2).
If you are using a Raspberry Pi 4 or earlier, consider a USB Zigbee dongle instead:
- SONOFF Zigbee 3.0 USB Dongle Plus (CC2652P,
/dev/ttyUSB0, 115200 baud) - SMLIGHT SLZB-06 (network or USB, CC2652P)
- ConBee II (Deconz,
/dev/ttyACM0, 38400 baud)
