version 5.1.10

- fix: matrix/sms_voipms notifications blocked the event loop on timeout;
  make send_notification async, dispatch all channel drivers as non-blocking
  tasks (asyncio.to_thread for sync drivers, asyncio.wait_for for async);
  update all call sites to fire-and-forget via create_task
- feat: add /about page with version, runtime, uptime counter, and repo link
- fix: hbc_mini plugin data format now matches full hbc client so Host
  Overview displays memory, disk, and network metrics correctly

+### hbc_mini — single-file client (no external dependencies)
+
+`scripts/hbc_mini.py` is a self-contained version of the heartbeat client that requires only Python 3.8+ and no external packages. Copy it to any host and run it directly — no virtualenv, no `pip install`.
+
+```bash
+# Basic usage
+python3 hbc_mini.py your-server.example.com
+
+# Run as daemon
+python3 hbc_mini.py -d your-server.example.com
+
+# Send a boot message
+python3 hbc_mini.py -b your-server.example.com
+
+# Send a one-off message
+python3 hbc_mini.py -m "maintenance starting" your-server.example.com
+```
+
+**Config:** `~/.hbc.json` (same keys as `~/.hbc.yaml`, JSON format). Example:
+
+```json
+{
+  "hb_port": 50003,
+  "interval": 30,
+  "plugins": {
+    "ping_monitor": {
+      "interval": 60,
+      "hosts": ["8.8.8.8", "192.168.1.1"]
+    },
+    "nagios_runner": {
+      "interval": 300,
+      "commands": [
+        {"name": "check_load", "command": "/usr/lib/nagios/plugins/check_load -w 5,4,3 -c 10,8,6"}
+      ]
+    }
+  }
+}
+```
+
+**Plugin availability:**
+
+| Plugin | Platform | Data source |
+|---|---|---|
+| `os_info` | all | `platform` stdlib |
+| `ping_monitor` | all | `ping` subprocess |
+| `nagios_runner` | all (not Windows) | subprocess |
+| `cpu_monitor` | Linux | `/proc/stat` |
+| `memory_monitor` | Linux | `/proc/meminfo` |
+| `disk_monitor` | Linux, macOS, BSD | `df -P` subprocess |
+| `network_monitor` | Linux | `/proc/net/dev` |
+
+**What is not available compared to the full `hbc`:**
+
+- No YAML config (use JSON instead)
+- No `filesystem_info` plugin
+- `cpu_monitor` does not report per-core usage or CPU frequency (no psutil)
+- Plugins cannot be loaded from external `.py` files — all plugins are compiled in
+
+Everything else — heartbeat protocol, ACK/CMD/UPD handling, `hb_install.sh`-based self-update, daemonize, syslog — is identical to the full client.

-# HBD/HBC Separation Refactoring
-
-## Overview
-
-The heartbeat monitoring system has been refactored into a modular package structure with separate client and server components. This allows users to install only what they need and provides clear separation of concerns.

-## Configuration Files
-
-### Client Configuration (hbd/client/config.py)
-
-Client-specific defaults:
-- `hb_port`: Port where hbd servers listen (default: 50003)
-- `interval`: Heartbeat interval in seconds (default: 10)
-- `plugins`: Per-plugin configuration
-- `thresholds`: Threshold configuration for monitoring
-
-### Server Configuration (hbd/server/config.py)
-
-Server-specific defaults:
-- `hb_port`: Port to listen for heartbeats (default: 50003)
-- `hbd_port`: HTTP API port (default: 50004)
-- `ws_port`: WebSocket port (default: 50005)
-- `logfile`: Log file path
-- `pushsrv`, `pushover_token`, etc.: Notification settings
-- `watchhosts`, `dyndnshosts`: Host monitoring
-- `smtpserver`, etc.: Email settings
-- `journal_*`: Message journaling settings
-
-## Installation Options
-
-### Install Core Only (minimal, PyYAML only)
-```bash
-pip install hbd
-```
-
-### Install Client Only (for monitoring)
-```bash
-pip install hbd[client]
-# Installs: PyYAML, psutil
-```
-
-### Install Server Only (for daemon)
-```bash
-pip install hbd[server]
-# Installs: PyYAML, websockets, mattermostdriver, aiohttp, Jinja2
-```
-
-### Install Everything
-```bash
-pip install hbd[all]
-# Installs all dependencies for both client and server
-```
-
-### Development Installation
-```bash
-pip install -e ".[dev]"
-# Includes all dependencies plus testing/linting tools
-```
-
-## Command-Line Interfaces
-
-### HBC (Client)
-```bash
-hbc [options] host1 [host2 ...]
-
-# Entry point: hbd.client.main:main
-# Location: hbd/client/main.py
-```
-
-### HBD (Server)
-```bash
-hbd [options]
-
-# Entry point: hbd.server.cli:main
-# Location: hbd/server/cli.py → hbd/server/main.py
-```
-
-## Import Changes
-
-### Client Code
-```python
-# Old imports
-from .config import load_config
-from .proto import dicttos, stodict
-from .plugin import PluginRegistry
-
-# New imports
-from .config import load_config          # Still in client/
-from ..common.proto import dicttos       # Moved to common/
-from .plugin import PluginRegistry       # Still in client/
-```
-
-### Server Code
-```python
-# Old imports
-from .config import load_config
-from .proto import stodict
-from .threshold import AlertLevel
-
-# New imports
-from .config import load_config          # Server-specific config
-from ..common.proto import stodict       # Moved to common/
-from ..client.threshold import AlertLevel # Client module
-```
-
-### Plugin Code
-```python
-# Old import
-from hbd.plugin import MonitorPlugin
-
-# New import
-from hbd.client.plugin import MonitorPlugin
-```
-
-## Benefits
-
-1. **Modular Installation**: Install only what you need
-   - Client-only systems don't need web server dependencies
-   - Server-only systems don't need psutil
-   
-2. **Clearer Architecture**: Explicit separation of concerns
-   - Client: System monitoring and data collection
-   - Server: Heartbeat reception, web UI, notifications
-   - Common: Shared protocol and utilities
-
-3. **Independent Evolution**: Client and server can evolve separately
-   - Different release cycles possible
-   - Clear API boundaries via common/
-
-4. **Smaller Footprint**: Reduced dependency installation
-   - Client: ~1 dependency (psutil)
-   - Server: ~4 dependencies (websockets, aiohttp, Jinja2, mattermostdriver)
-
-## Migration Guide
-
-### For Existing Installations
-
-1. **Reinstall the package**:
-   ```bash
-   pip install -e ".[all]"  # For development
-   # or
-   pip install hbd[all]     # For production
-   ```
-
-2. **Configuration files remain unchanged**:
-   - Both client and server read from `~/.hb.yaml`
-   - All existing config keys are supported in both configs
-   - Server has additional keys (journal, websocket, email, etc.)
-   - Client has minimal keys (interval, plugins, thresholds)
-
-3. **Commands remain the same**:
-   - `hbc` command works identically
-   - `hbd` command works identically
-
-### For New Deployments
-
-1. **Client-only system** (monitoring host):
-   ```bash
-   pip install hbd[client]
-   hbc server1.example.com server2.example.com
-   ```
-
-2. **Server-only system** (monitoring daemon):
-   ```bash
-   pip install hbd[server]
-   hbd -c /etc/hbd.yaml -f
-   ```
-
-3. **Combined system** (dev/test):
-   ```bash
-   pip install hbd[all]
-   ```
-
-## Testing
-
-All imports and entry points have been tested and validated:
-- ✅ Package imports work correctly
-- ✅ `hbc` command entry point functional
-- ✅ `hbd` command entry point functional
-- ✅ Optional dependencies properly configured
-- ✅ All internal imports updated
-
-## Files Archived
-
-The following files were renamed to avoid conflicts:
-- `hbd/config.py` → `hbd/config.py.old` (split into client/server configs)
-- `hbd/hbc_old.py` → `hbd/hbc_old.py.bak` (backup file)
-
-## Next Steps
-
-1. Test client functionality with a monitoring host
-2. Test server functionality with web UI and notifications
-3. Update documentation (README.md) with new structure
-4. Consider publishing to PyPI with new structure
-5. Update any deployment scripts/Dockerfiles to use optional dependencies

-Plan the following changes, ask questions to clarify before implementing
-
-Re-factor the notification system:
-- use available libraries for pushover, matrix, email and sms notifications.
-- notifications have a title/subject:  alert_type (recover/warning/critical), a body (info from threshold check) and a link to the host plugin metrix page
-- define a list of notification channels for each user
-- notifications are dispatched to users that are listed as managers for the host
-
-
-
-1 - correct
-2 - for now channels are defined globaly 
-3 - matrix-nio)sounds good, homeserver URL, access token, room ID per channel?
-4 - use the REST api provided by https://voip.ms/api/v1/rest.php
-5 - The page does not exist yet, point at the host tab in the /plugins
-6 - per-channel minimum severity is a good idea, go fo it
-7 - yes
-
-1 - use base_url, there might not have been any incoming requests yet
-2 - use same asyncio loop for matrix-nio
-3 - for now, just silently do nothing
