-| Distribution | Group for serial access |

-| Debian, Ubuntu, Raspberry Pi OS | `dialout` |
-| Arch Linux, CachyOS | `uucp` |
+**Recommended — udev rules (one-time, works in Cursor without re-login):**
 
 ```bash
-# Debian / Ubuntu / Pi
-sudo usermod -aG dialout $USER
+sudo ./scripts/install-udev-rules.sh
+# unplug and replug the Arduino
+```
 
+This installs PlatformIO’s `99-platformio-udev.rules` (covers CH340 clone Nanos and other common adapters).
+
+**Alternative — group membership:**
+
+```bash
 # Arch / CachyOS
 sudo usermod -aG uucp $USER
 ```
 
-Log out and back in after adding your user to the group.
+You must **fully log out of the desktop** (not just reboot or open a new terminal) so `id` shows the new group. Cursor’s terminal often keeps the old group list until you restart Cursor after logging out.
+
+**Immediate workaround** (no sudo, current terminal only):
+
+```bash
+sg uucp -c "$HOME/.platformio/penv/bin/pio run -t upload"
+```
+
+Verify access: `test -w /dev/ttyUSB0 && echo ok`

-Optional CSV capture over USB is documented in [pi-instructions.md](pi-instructions.md).
+On the Pi, use the curses TUI to set targets and monitor the chamber (SSH with a TTY: `ssh -t`):

+```bash
+python3 scripts/capture_csv.py tui

+Keys: `0` idle · `t` target · `p` material presets · `f`/`F` fan · `l` CSV log · `a` autotune · `:` command · `q` quit

+Headless CSV-only logging (e.g. systemd) is documented in [pi-instructions.md](pi-instructions.md).
