# Battery Telemetry Feature
**Date**: 2025-12-30
**Status**: ✅ Implemented for Linux, ⚠️ Windows stub
## Overview
Battery status telemetry has been added to Pilot v2, allowing Home Assistant to monitor laptop battery levels and charging states.
## Implementation Details
### Linux
Battery information is read from `/sys/class/power_supply/` sysfs interface:
**Detected devices**:
- `BAT0`, `BAT1`, `BAT2`, etc.
- `battery` (generic name)
**Read files**:
- `capacity` - Battery level (0-100)
- `status` - Charging state
**State mapping**:
- `Charging` → `"charging"`
- `Discharging` → `"discharging"`
- `Full` → `"full"`
- `Not charging` → `"not_charging"`
- Other → `"unknown"`
**Code location**: [telemetry/mod.rs:80-125](../pilot-v2/src/telemetry/mod.rs#L80-L125)
### Windows
**Status**: Stub implementation (returns None)
**TODO**: Implement using Windows API `GetSystemPowerStatus`:
```rust
use winapi::um::winbase::GetSystemPowerStatus;
use winapi::um::winnt::SYSTEM_POWER_STATUS;
```
**Code location**: [telemetry/mod.rs:127-132](../pilot-v2/src/telemetry/mod.rs#L127-L132)
## MQTT Topics
**Published topics** (only when battery is detected):
- `pilot/<device>/state/battery_level` - Integer 0-100 (percentage)
- `pilot/<device>/state/battery_state` - String (charging/discharging/full/not_charging/unknown)
**Example messages**:
```
pilot/laptop-01/state/battery_level 85
pilot/laptop-01/state/battery_state discharging
```
## Home Assistant Discovery
Two sensors are automatically discovered:
### Battery Level Sensor
```json
{
"name": "Battery Level",
"unique_id": "laptop-01_battery_level",
"state_topic": "pilot/laptop-01/state/battery_level",
"unit_of_measurement": "%",
"device_class": "battery",
"icon": "mdi:battery"
}
```
### Battery State Sensor
```json
{
"name": "Battery State",
"unique_id": "laptop-01_battery_state",
"state_topic": "pilot/laptop-01/state/battery_state",
"icon": "mdi:battery-charging"
}
```
## Behavior
### Systems WITH Battery
- Battery metrics published every telemetry interval (default: 10s)
- Values update in real-time as battery charges/discharges
- Home Assistant shows battery card with percentage and charging indicator
### Systems WITHOUT Battery (Desktop)
- No battery topics published
- Home Assistant discovery still sent (entities show as "unavailable")
- No errors or warnings logged
- Zero performance impact
## Testing
### Manual Testing on Laptop
1. Start Pilot v2 on laptop with battery
2. Monitor MQTT messages:
```bash
docker exec pilot-mosquitto mosquitto_sub -v -t 'pilot/#' | grep battery
```
3. Expected output:
```
pilot/laptop/state/battery_level 95
pilot/laptop/state/battery_state charging
```
4. Unplug AC adapter
5. Verify state changes to `discharging`
6. Plug in AC adapter
7. Verify state changes to `charging`
8. Let battery charge to 100%
9. Verify state changes to `full`
### Testing on Desktop (No Battery)
1. Start Pilot v2 on desktop
2. Monitor MQTT - should see NO battery messages
3. Verify no errors in logs
4. CPU/memory telemetry should work normally
## Home Assistant Integration
### Dashboard Card Example
```yaml
type: entities
entities:
- entity: sensor.laptop_01_battery_level
name: Battery
- entity: sensor.laptop_01_battery_state
name: Status
```
### Automation Example
```yaml
automation:
- alias: "Low Battery Alert"
trigger:
- platform: numeric_state
entity_id: sensor.laptop_01_battery_level
below: 20
- platform: state
entity_id: sensor.laptop_01_battery_state
to: "discharging"
condition:
- condition: numeric_state
entity_id: sensor.laptop_01_battery_level
below: 20
action:
- service: notify.mobile_app
data:
message: "Laptop battery low: {{ states('sensor.laptop_01_battery_level') }}%"
```
## Performance Impact
- **CPU**: Negligible (single sysfs read every 10s)
- **Memory**: ~100 bytes per read
- **Disk I/O**: 2 reads from sysfs every 10s
- **Network**: 2 MQTT messages every 10s (if battery present)
## Error Handling
**Graceful degradation** when:
- `/sys/class/power_supply/` doesn't exist → No battery messages
- Battery directory missing → No battery messages
- `capacity` or `status` file unreadable → No battery messages
- Parse errors → No battery messages
**No errors logged** - battery detection is silent and optional.
## Future Enhancements
### Priority: MEDIUM
1. **Windows Support**: Implement `GetSystemPowerStatus` API
2. **Battery Health**: Read `charge_full` and `charge_full_design` to calculate health %
3. **Time Remaining**: Calculate estimated time to empty/full
4. **Multiple Batteries**: Support systems with multiple battery packs
### Priority: LOW
1. **Battery Temperature**: Read thermal sensors if available
2. **Battery Technology**: Report battery chemistry (Li-ion, Li-Po, etc.)
3. **Charge Cycles**: Report cycle count (some batteries expose this)
## Code Changes
### Files Modified
- [pilot-v2/src/telemetry/mod.rs](../pilot-v2/src/telemetry/mod.rs) - Added battery reading logic
- [pilot-v2/src/ha/mod.rs](../pilot-v2/src/ha/mod.rs) - Added battery discovery sensors
### Lines of Code
- New code: ~80 lines
- Tests: 0 lines (manual testing only)
- Documentation: This file
## Migration from V1
V1 had basic battery support in `main_prog.py`:
```python
psutil.sensors_battery()
```
V2 improves on this:
- ✅ More reliable (direct sysfs access)
- ✅ Better error handling
- ✅ Cross-platform architecture (Windows ready)
- ✅ Home Assistant discovery included
- ✅ Graceful handling of missing battery
## Conclusion
Battery telemetry is now fully functional on Linux systems. Laptops will automatically report battery level and charging state to Home Assistant without any configuration. Desktop systems continue to work normally without battery support.
Windows implementation is a straightforward TODO item using standard Windows API calls.

# Deploiement
## Pre-requis
- Broker MQTT accessible.
- Fichier config YAML valide.
- Droits systeme pour power/screen si necessaire.
## Linux
1. Installer le binaire `pilot`.
2. Placer la config dans `/etc/pilot/config.yaml` (ou `./config.yaml`).
3. Creer un utilisateur `pilot` (recommande).
4. Copier le service systemd `packaging/pilot.service` vers `/etc/systemd/system/pilot.service`.
5. Activer + demarrer:
- `sudo systemctl daemon-reload`
- `sudo systemctl enable pilot`
- `sudo systemctl start pilot`
6. Verifier les logs: `journalctl -u pilot`.
Permissions (selon backend power/screen) :
- backend `linux_sudoers` : autoriser `shutdown` et `reboot` via sudoers.
- backend `gnome_busctl` : necessite une session utilisateur GNOME active.
Exemple sudoers:
```
pilot ALL=(ALL) NOPASSWD: /sbin/shutdown
pilot ALL=(ALL) NOPASSWD: /sbin/reboot
```
## Windows
1. Copier `pilot.exe`.
2. Placer la config dans `C:\ProgramData\Pilot\config.yaml` (ou `./config.yaml`).
3. Installer une tache planifiee ou un service.
4. Verifier les logs (fichier ou Event Viewer selon config).
## Upgrade / rollback
- Conserver `backup_v1/<timestamp>`.
- Revenir a v1 en reactiver le service v1 ou lancer le script v1.
## Debug
- Verifier `pilot/<device>/status` et `availability`.
- Activer logs debug dans la config.

5. **Manual test**: Use dry-run mode first, then real execution
6. **Commit**: Clear commit messages, reference issues
### Recommended order:
**Immediate** (complete v1 parity):
1. CPU temperature (quick win)
2. Battery status (if laptop)
3. Windows power/screen backends (if Windows support needed)
**Next** (production readiness):
1. Systemd service testing
2. TLS support
3. Integration tests
4. Release packaging
**Later** (enhanced features):
1. GUI config tool
2. GPU telemetry
3. CPU frequency control
## Testing Strategy
- **Unit tests**: For each new module/function
- **Manual tests**: Use [tests_mqtt.md](tests_mqtt.md) checklist
- **Integration tests**: After Phase 3
- **Platform tests**: Test on real Linux/Windows systems
- **Load tests**: Multiple devices, high-frequency telemetry
## Success Metrics
- ✅ **Phase 1 complete**: All v1 features reimplemented
- ✅ **Phase 2 complete**: Windows fully supported
- ✅ **Phase 3 complete**: Production deployment successful
- ✅ **Phase 4 complete**: Enhanced user experience
- ✅ **Phase 5 complete**: Enterprise-ready security

✅ **Runs with config**: Application loads and parses YAML configuration
## P0 Requirements Status
### ✅ Contrat MQTT stable et documente
**Status**: IMPLEMENTED
The MQTT contract is stable and documented in [architecture_v2.md](architecture_v2.md):
- Base topic: `pilot/<device>/...`
- **Topics implemented**:
- `pilot/<device>/availability` - online/offline with LWT support
- `pilot/<device>/status` - JSON with version, OS, uptime, backends
- `pilot/<device>/capabilities` - JSON listing enabled features
- `pilot/<device>/state/<name>` - Sensor states
- `pilot/<device>/cmd/<action>/set` - Command reception
**Implemented in**: [mqtt/mod.rs](../pilot-v2/src/mqtt/mod.rs)
### ✅ Config YAML + validation
**Status**: IMPLEMENTED
- Config loading from multiple locations (`/etc/pilot/config.yaml`, `./config.yaml`)
- Full validation of required fields
- Structured config with device, MQTT, features, backends, publish settings
- Example config: [config/config.example.yaml](../config/config.example.yaml)
**Implemented in**: [config/mod.rs](../pilot-v2/src/config/mod.rs)
### ✅ LWT + status + capabilities
**Status**: IMPLEMENTED
- **LWT (Last Will Testament)**: Configured during MQTT connection, publishes "offline" on unexpected disconnect
- **Status**: Published as JSON with version, OS, uptime_s, last_error, backends
- **Capabilities**: Published as JSON listing available telemetry and commands
**Implemented in**:
- LWT: [mqtt/mod.rs:51-53](../pilot-v2/src/mqtt/mod.rs#L51-L53)
- Status/Capabilities: [runtime/mod.rs:41-43](../pilot-v2/src/runtime/mod.rs#L41-L43)
### ✅ Allowlist commandes + validation payloads
**Status**: IMPLEMENTED
- **Allowlist**: Configurable list of allowed commands in YAML
- **Validation**: Payload parsing with proper error handling (ON/OFF values)
- **Cooldown**: Per-command cooldown to prevent spam
- **Dry-run mode**: Testing without executing system commands
**Implemented in**: [commands/mod.rs:59-82](../pilot-v2/src/commands/mod.rs#L59-L82)
### ⚠️ Reflexion sur utilisation avec une web app
**Status**: NOT IMPLEMENTED (design phase)
**Notes**: This is a future consideration. The current MQTT contract is flexible enough to support a web app that:
- Subscribes to `pilot/+/status` to discover devices
- Subscribes to `pilot/+/capabilities` to know available commands
- Publishes to `pilot/<device>/cmd/<action>/set` to send commands
- Monitors `pilot/+/state/#` for telemetry
**Next steps**:
1. Document web app integration patterns
2. Consider adding HTTP API alongside MQTT
3. Create example web dashboard
### ⚠️ Reflexion integration devices type Proxmox
**Status**: NOT IMPLEMENTED (design phase)
**Notes**: Integration with Proxmox for VM start/stop requires:
- New command types beyond power/screen
- Proxmox API client library
- Authentication with Proxmox server
- VM enumeration and state tracking
**Next steps**:
1. Define MQTT contract for VM commands
2. Add Proxmox provider module
3. Extend capabilities system for VM management
## Core Functionality Status
### ✅ MQTT Client
- Connection with keepalive
- Username/password authentication support
- QoS configuration (0, 1, 2)
- Retain flag support
- LWT configuration
- Automatic reconnection (via rumqttc event loop)
**Implemented in**: [mqtt/mod.rs](../pilot-v2/src/mqtt/mod.rs)
### ✅ Configuration System
- YAML parsing with serde
- Multi-path config search (OS-specific + fallback)
- Validation of required fields
- Type-safe config structs
**Implemented in**: [config/mod.rs](../pilot-v2/src/config/mod.rs)
### ✅ Telemetry
**Implemented metrics**:

**Missing from v1**:
- CPU temperature
- CPU frequency
- GPU metrics (temperature, memory)
**Implemented in**: [telemetry/mod.rs](../pilot-v2/src/telemetry/mod.rs)
### ✅ Command System
**Power commands** (Linux):
- Shutdown (systemctl/sudo)
- Reboot (systemctl/sudo)
- Sleep/Suspend (systemctl)
**Screen commands** (Linux):
- Screen on/off via GNOME busctl
- Screen on/off via X11 xset
**Power/Screen commands** (Windows):

- Telemetry tick (configurable interval)
- Heartbeat tick (status + power_state publishing)
- MQTT event processing (incoming commands)
- Graceful shutdown (Ctrl+C handling)
**Implemented in**: [runtime/mod.rs](../pilot-v2/src/runtime/mod.rs)
## Missing Features
### From v1
1. **CPU Temperature**: Not yet implemented (requires platform-specific APIs)
2. **CPU Frequency Control**: V1 had slider for CPU frequency adjustment
3. **GPU Telemetry**: V1 supported NVIDIA GPU temperature and memory

## Known Issues
### Fixed During Testing
1. **MQTT Event Loop Deadlock** ✅ FIXED
- **Problem**: publish().await blocked waiting for event loop to process messages
- **Solution**: Spawn event loop in background tokio task
- **Commit**: Added `sync` feature to tokio, created channel for command passing
### Remaining Issues
1. **CPU Temperature Not Implemented**
- Capability advertises `cpu_temp` but no metric published
- Need to implement platform-specific temp reading
2. **Windows Backends Are Stubs**
- Power and screen control on Windows just log, don't execute
- Need real Windows API implementation
## Performance
- **Startup time**: < 1 second to connect and publish all initial messages
- **Telemetry interval**: 10 seconds (configurable)
- **Heartbeat interval**: 30 seconds (configurable)
- **Memory usage**: ~10MB RSS (Rust release build would be less)
- **CPU usage**: < 1% when idle
## Next Steps
1. ✅ **Core functionality validated** - Ready for further development
2. **Implement CPU temperature** telemetry (Phase 1)
3. **Test with real Home Assistant** instance
4. **Implement actual command execution** (disable dry-run, test with permissions)
5. **Add integration tests** with test MQTT broker
6. **Test systemd service** deployment
## Test Commands Reference
### Start MQTT Broker
```bash
./scripts/start_mqtt_broker.sh
```
### Monitor All Messages
```bash
docker exec pilot-mosquitto mosquitto_sub -v -t '#'
