python-pooldose 0.4.0

Unoffical async Python client for SEKO PoolDose devices

python-pooldose

Unofficial async Python client for SEKO 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.

Installation

pip install python-pooldose

Example Usage

Basic Example

import asyncio
import json
from pooldose.client import PooldoseClient
from pooldose.request_handler import RequestStatus

HOST = "192.168.1.100"  # Change this to your device's host or IP address
TIMEOUT = 30

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()
    if status != RequestStatus.SUCCESS:
        print(f"Error connecting to device: {status}")
        return
    
    print(f"Connected to {HOST}")

Advanced Usage

Connection Management

# Recommended: Separate initialization and connection
client = PooldoseClient("192.168.1.100", timeout=30)
status = await client.connect()

# Check connection status
if client.is_connected:
    print("Client is connected")
else:
    print("Client is not connected")

Error Handling

from pooldose.request_handler import RequestStatus

client = PooldoseClient("192.168.1.100")
status = await client.connect()

if status == RequestStatus.SUCCESS:
    print("Connected successfully")
elif status == RequestStatus.HOST_UNREACHABLE:
    print("Could not reach device")
elif status == RequestStatus.PARAMS_FETCH_FAILED:
    print("Failed to fetch device parameters")
elif status == RequestStatus.API_VERSION_UNSUPPORTED:
    print("Unsupported API version")
else:
    print(f"Other error: {status}")

API Reference

PooldoseClient

Constructor

PooldoseClient(host, timeout=10, include_sensitive_data=False)

Parameters:

• host (str): The hostname or IP address of the device
• timeout (int): Request timeout in seconds (default: 10)
• include_sensitive_data (bool): Whether to include sensitive data like WiFi passwords (default: False)

Methods

• connect() - Connect to device and initialize all components
• static_values() - Get static device information
• instant_values() - Get current sensor readings and device state
• available_types() - Get all available entity types
• available_sensors() - Get available sensor configurations
• available_binary_sensors() - Get available binary sensor configurations
• available_numbers() - Get available number configurations
• available_switches() - Get available switch configurations
• available_selects() - Get available select configurations

Properties

• host - Device hostname or IP address
• timeout - Request timeout in seconds

InstantValues

Dictionary Interface

# Reading
value = instant_values["sensor_name"]
value = instant_values.get("sensor_name", default)
exists = "sensor_name" in instant_values

# Writing (async)
await instant_values.__setitem__("switch_name", True)

Type-specific Methods

# Getters
sensors = instant_values.get_sensors()
binary_sensors = instant_values.get_binary_sensors()
numbers = instant_values.get_numbers()
switches = instant_values.get_switches()
selects = instant_values.get_selects()

# Setters (async, with validation)
await instant_values.set_number("ph_target", 7.2)
await instant_values.set_switch("stop_dosing", True)
await instant_values.set_select("water_meter_unit", 1)

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:

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