Changelog

v1.4.0

✨ New Features

CPU voltage on non-Pi hosts

• voltage now reads CPU core voltage from hwmon (lm-sensors) when vcgencmd is not available, so the sensor works on x86 / Ubuntu hosts with a supported Super-I/O driver exposing a Vcore rail (e.g. via sensors-detect).
• When neither vcgencmd nor an hwmon Vcore sensor is present (typical on x86 mini-PCs with no Super-I/O voltage chip), the sensor no longer reports a misleading 0 V — it reports no value (shown as unavailable in Home Assistant when use_availability is enabled).

Interactive configurator

• New rpi-mqtt-monitor --config (-c) launches a terminal UI for editing config.py.
• Navigate settings with the ↑/↓ arrows; each setting shows its description and default value.
• Press Enter to edit — booleans toggle; numbers and strings open an inline editor pre-filled with the current value (Esc cancels). Press s to save, q to quit.
• Edits are written back preserving comments, ordering, formatting, inline comments and the existing quote style; complex settings (lists, the output function) are shown read-only with a note to edit them in the file.

IP address sensors

• New opt-in sensors expose the device's network addresses: Local IPv4, Local IPv6, External IPv4, and External IPv6.
• Local addresses are detected via a UDP socket (no traffic sent); external addresses are resolved through an outbound HTTPS call to api.ipify.org / api6.ipify.org.
• All four are disabled by default; the installer now prompts to enable the local and/or external IP sensors.

SSD health monitoring

• New per-drive SSD health sensors gathered from smartctl (smartmontools): SMART overall status, wear / life used (%), power-on hours, and data written (TB).
• Works with both NVMe and SATA SSDs — NVMe values come from the uniform SMART health log; SATA wear and data-written are best-effort from the vendor attribute table.
• Installer autodetects non-rotating drives and prompts to install smartmontools and enable the sensors.
• smartctl needs root: the installer also adds a passwordless sudoers drop-in so the sensors populate under cron as well as the systemd service.

v1.3.3 (2026-06-13)

✨ New Features

NVIDIA & AMD GPU monitoring

• GPU monitoring now supports NVIDIA and AMD alongside Intel.
• NVIDIA sensors via the native pynvml library (nvidia-ml-py): Utilization %, Memory %, Frequency (MHz), Power (W), Temperature (°C).
• AMD sensors read straight from sysfs (/sys/class/drm, in-kernel amdgpu driver) with no external tools: Utilization %, Memory %, Frequency (MHz), Power (W), Temperature (°C).
• Unlike Intel (intel_gpu_top, root-only), NVIDIA and AMD reads do not require root, so they also populate under cron.
• Installer now autodetects the GPU vendor (lspci / nvidia-smi / amdgpu) and prompts to enable the matching sensors, installing only what each vendor needs.

🛠 Improvements

• Intel GPU sensor now works with older intel-gpu-tools builds that don't support the -m flag.

🐛 Bug Fixes

• Fixed on-screen display (-d) rendering: the model name carried a trailing NUL byte on Raspberry Pi (pulling the box border left) and a leading space on other platforms (shifting the Model/Manufacturer rows one character right). Both values are now cleaned at the source, which also tidies the MQTT payloads.

v1.3.2 (2026-06-13)

✨ New Features

• Track free space on multiple paths/drives via the new used_space_paths option — each entry ({'name': ..., 'path': ...}) becomes its own "used space" sensor.

🛠 Improvements

• Disk usage is now measured with df, improving support for multiple mounts.

v1.3.1 (2026-06-12)

🛠 Improvements

• Improved display / monitor on-off control.
• Published the documentation site under docs/.

v1.3.0 (2026-06-12)

A feature-packed release focused on display control, secure/flexible MQTT connectivity, Intel GPU monitoring, and a substantially improved installer & on-screen display.

✨ New Features

Display / monitor on-off control

• Turn attached displays on/off from Home Assistant via new Monitor On / Monitor Off buttons.
• Auto-detecting backend that works across environments: X11 (xset DPMS), wlroots Wayland (wlr-randr), Raspberry Pi (vcgencmd), and GNOME / generic Wayland (ddcutil over DDC/CI).
• Optional display_on_command / display_off_command config overrides for custom setups.
• Installer now detects your display backend and offers to install the required tool and permissions (including ddcutil + i2c-dev + i2c group setup).

MQTT over TLS/SSL

• New mqtt_tls option to connect to brokers over SSL (port 8883), with mqtt_tls_ca_certs (self-signed CA) and mqtt_tls_insecure options.
• Installer prompts for SSL and auto-suggests port 8883.

MQTT over WebSockets

• New mqtt_websockets + mqtt_websocket_path options to connect via MQTT-over-WebSockets (ws/wss).
• Installer prompts for WebSockets and path, with WebSocket-aware port defaults (9001 for ws, 8084 for wss).

Intel GPU monitoring

• Four new sensors from intel_gpu_top: Render/3D busy %, Video busy %, Frequency (MHz), and Power (W).
• Installer can install intel-gpu-tools and enable the sensors on request.
• Note: requires running as the systemd service (root).

🛠 Improvements

• Reworked installer — new welcome screen, clearer prompts, better error handling, and a smarter scheduling step that recommends the systemd service when service-only features (display control, Intel GPU) are enabled.
• Improved on-screen display (-d) with refreshed UI, progress bars, and an update-progress view.
• Expanded and clarified README documentation.

🐛 Bug Fixes

• Fixed restart and shutdown behavior on Ubuntu.
• Uninstaller now removes the symlink in bin.
• Various smaller bug fixes across the installer and main script.
