# python-pooldose
Unofficial async Python client for [SEKO](https://www.seko.com/) Pooldosing systems. SEKO is a manufacturer of various monitoring and control devices for Pools and Spas.
This client uses an undocumented local HTTP API. It provides live readings for pool sensors such as temperature, pH, ORP/Redox, as well as status information and control over the dosing logic.

## Features
- **Async/await support** for non-blocking operations
- **Dynamic sensor discovery** based on device model and firmware
- **Dictionary-style access** to instant values
- **Type-specific getters** for sensors, switches, numbers, selects
- **Secure by default** - WiFi passwords excluded unless explicitly requested
- **Comprehensive error handling** with detailed logging

## Prerequisites
1. Install and set-up the PoolDose devices according to the user manual.
   1. In particular, connect the device to your WiFi network.
   2. Identify the IP address or hostname of the device.
2. Browse to the IP address or hostname (default port: 80).
   1. Try to log in to the web interface with the default password (0000).
   2. Check availability of data in the web interface.
3. Optionally: Block the device from internet access to ensure cloudless-only operation.

## SSL/HTTPS Support

The client supports SSL/HTTPS connections for secure communication with your PoolDose device. This is particularly useful when the device is configured for HTTPS or when connecting over untrusted networks.

### Basic SSL Configuration

```python
from pooldose.client import PooldoseClient

# Enable SSL with default settings (port 443, certificate verification enabled)
client = PooldoseClient("192.168.1.100", use_ssl=True)
status = await client.connect()
```

### SSL Configuration Options

```python
# Custom HTTPS port
client = PooldoseClient("192.168.1.100", use_ssl=True, port=8443)

# Disable SSL certificate verification (not recommended for production)
client = PooldoseClient("192.168.1.100", use_ssl=True, ssl_verify=False)

# Complete SSL configuration example
client = PooldoseClient(
    host="pool-device.local",
    timeout=30,
    use_ssl=True,
    port=8443,
    ssl_verify=True,  # Verify SSL certificates
    include_sensitive_data=False
)
```

### SSL Security Considerations

- **Certificate Verification**: By default, SSL certificate verification is enabled (`ssl_verify=True`). This ensures secure connections but requires valid certificates.
- **Self-signed Certificates**: If your device uses self-signed certificates, set `ssl_verify=False`. Note that this reduces security.
- **Port Configuration**: Use the `port` parameter to specify custom HTTPS ports. Defaults to 443 for HTTPS and 80 for HTTP.
- **Connection Timeouts**: Consider increasing the `timeout` value for SSL connections as they may take longer to establish.

### Migration from HTTP to HTTPS

To migrate existing code from HTTP to HTTPS:

```python
# Before (HTTP)
client = PooldoseClient("192.168.1.100")

# After (HTTPS with SSL verification)
client = PooldoseClient("192.168.1.100", use_ssl=True)

# After (HTTPS with custom port and no verification)
client = PooldoseClient("192.168.1.100", use_ssl=True, port=8443, ssl_verify=False)
```

## Installation

```bash
pip install python-pooldose
```

## Example Usage

### Basic Example
```python
import asyncio
import json
from pooldose.client import PooldoseClient
from pooldose.request_status import RequestStatus

HOST = "192.168.1.100"  # Change this to your device's host or IP address

async def main() -> None:
    """Demonstrate PooldoseClient usage with new dictionary-based API."""
    
    # Create client instance (excludes WiFi passwords by default)
    client = PooldoseClient(host=HOST, timeout=TIMEOUT)
    
    # Optional: Include sensitive data like WiFi passwords
    # client = PooldoseClient(host=HOST, timeout=TIMEOUT, include_sensitive_data=True)
    
    # Connect to device
    status = await client.connect()

    print("\nAvailable sensors:")
    for name, sensor in client.available_sensors().items():
        print(f"  {name}: key={sensor.key}, type={sensor.type}")
        if sensor.conversion is not None:
            print(f"    conversion: {sensor.conversion}")

    # --- Get static values ---
    status, static_values = client.static_values()
    if status == RequestStatus.SUCCESS:
        print(f"Device Name: {static_values.sensor_name}")
        print(f"Serial Number: {static_values.sensor_serial_number}")
        print(f"Firmware Version: {static_values.sensor_fw_version}")

    # --- Get instant values ---
    status, instant_values = await client.instant_values()
    if status != RequestStatus.SUCCESS:
        print(f"Error getting instant values: {status}")
        return

    # --- Dictionary-style access ---
    
    # Get all sensors at once
    print("\nAll sensor values:")
    sensors = instant_values.get_sensors()
    for key, value in sensors.items():
        if isinstance(value, tuple) and len(value) >= 2:
            print(f"  {key}: {value[0]} {value[1]}")

    # Dictionary-style individual access
    if "temperature" in instant_values:
        temp = instant_values["temperature"]
        print(f"Temperature: {temp[0]} {temp[1]}")

    # Get with default
    ph_value = instant_values.get("ph", "Not available")
    print(f"pH: {ph_value}")

    # --- Setting values ---
    
    # Set number values
    if "ph_target" in instant_values.get_numbers():
        result = await instant_values.set_number("ph_target", 7.2)
        print(f"Set pH target to 7.2: {result}")

    # Set switch values
    if "stop_pool_dosing" in instant_values.get_switches():
        result = await instant_values.set_switch("stop_pool_dosing", True)
        print(f"Set stop pool dosing: {result}")

## Supported Devices

This client has been tested with:
- **PoolDose Double/Dual WiFi** (Model: PDPR1H1HAW100, FW: 539187)

Other SEKO PoolDose models may work but are untested. The client uses JSON mapping files to adapt to different device models and firmware versions (see e.g. `src/pooldose/mappings/model_PDPR1H1HAW100_FW539187.json`).

> **Note:** The other JSON files in the `docs/` directory define the default English names for the data keys of the PoolDose devices. These mappings are used for display and documentation purposes.

## Security

By default, the client excludes sensitive information like WiFi passwords from device info. To include sensitive data:

```python
client = PooldoseClient(
    host="192.168.1.100", 
    include_sensitive_data=True
)
status = await client.connect()
```

## Changelog

For detailed release notes and version history, please see [CHANGELOG.md](CHANGELOG.md).

### Latest Release (0.4.6)
- Device returns unit for pH values, which have physically no unit. Fixed by replacing such occurrences with None.
