Python library for Pentair IntelliCenter pool control systems

pyintellicenter

Python library for communicating with Pentair IntelliCenter pool control systems over local network.

Alpha Release: This library is in early development. API may change between versions.

Features

• Dual Transport Support: TCP (port 6681) and WebSocket (port 6680) connections
• Local Communication: Direct connection to IntelliCenter (no cloud required)
• Real-time Updates: Push-based notifications via NotifyList protocol
• mDNS Discovery: Automatically find IntelliCenter units on your network
• Async/Await: Built on Python asyncio for efficient I/O
• Type Annotations: Full type hints for IDE support and static analysis
• Robust Connection Handling: Automatic reconnection with exponential backoff
• Circuit Breaker Pattern: Prevents connection storms during outages
• Home Assistant Ready: Convenience helpers for integration development

Installation

pip install pyintellicenter

Requirements

• Python 3.13+
• Pentair IntelliCenter controller (i5P, i8P, i10P, or similar)
• Local network access to IntelliCenter

Quick Start

Basic Connection (TCP)

import asyncio
from pyintellicenter import ICModelController, PoolModel, ICConnectionHandler

async def main():
    # Create a model to hold equipment state
    model = PoolModel()

    # Create controller connected to your IntelliCenter
    controller = ICModelController("192.168.1.100", model)

    # Use ICConnectionHandler for automatic reconnection
    handler = ICConnectionHandler(controller)
    await handler.start()

    # Access system information
    print(f"Connected to: {controller.system_info.prop_name}")
    print(f"Software version: {controller.system_info.sw_version}")

    # List all equipment
    for obj in model:
        print(f"{obj.sname} ({obj.objtype}): {obj.status}")

    # Control equipment - turn on pool
    await controller.set_circuit_state("POOL", True)

    # Clean shutdown
    await handler.stop()

asyncio.run(main())

WebSocket Connection

from pyintellicenter import ICConnection

async def main():
    # Use WebSocket transport instead of TCP
    async with ICConnection("192.168.1.100", transport="websocket") as conn:
        response = await conn.send_request(
            "GetParamList",
            condition="",
            objectList=[{"objnam": "INCR", "keys": ["VER", "SNAME"]}]
        )
        print(response)

asyncio.run(main())

Auto-Discovery

from pyintellicenter import discover_intellicenter_units

async def main():
    # Find all IntelliCenter units on the network
    units = await discover_intellicenter_units(timeout=5.0)

    for unit in units:
        print(f"Found: {unit.name} at {unit.host}:{unit.port}")
        print(f"  Model: {unit.model}")
        print(f"  WebSocket port: {unit.ws_port}")

asyncio.run(main())

API Reference

ICConnection

Low-level connection wrapper supporting both TCP and WebSocket transports.

from pyintellicenter import ICConnection

# TCP connection (default)
conn = ICConnection("192.168.1.100")
conn = ICConnection("192.168.1.100", transport="tcp")
conn = ICConnection("192.168.1.100", port=6681)

# WebSocket connection
conn = ICConnection("192.168.1.100", transport="websocket")
conn = ICConnection("192.168.1.100", port=6680, transport="websocket")

# Full configuration
conn = ICConnection(
    host="192.168.1.100",
    port=6681,                    # Default: 6681 (TCP), 6680 (WebSocket)
    transport="tcp",              # "tcp" or "websocket"
    response_timeout=30.0,        # Request timeout in seconds
    keepalive_interval=90.0,      # Keepalive interval in seconds
    notification_queue_size=100,  # Max queued notifications
)

# Usage as context manager
async with ICConnection("192.168.1.100") as conn:
    response = await conn.send_request("GetParamList", ...)

# Manual connection management

ICConnectionHandler

Wraps a controller with automatic reconnection and lifecycle callbacks.

from pyintellicenter import ICConnectionHandler, ICConnectionHandlerCallbacks

callbacks = ICConnectionHandlerCallbacks(
    on_started=lambda: print("Connected!"),
    on_stopped=lambda: print("Stopped"),
    on_disconnected=lambda: print("Disconnected"),
    on_reconnected=lambda: print("Reconnected!"),
    on_retrying=lambda attempt, delay: print(f"Retry {attempt} in {delay}s"),
)

    controller,
    callbacks=callbacks,
    time_between_reconnects=30.0,    # Initial reconnect delay
    disconnect_debounce_time=15.0,   # Grace period before disconnect callback
)

# Start connection (waits for first connection)
await handler.start()

# Access the underlying controller
print(handler.controller.system_info.prop_name)

# Check connection state
print(f"Connected: {handler.connected}")

# Stop with cleanup
await handler.stop()

PoolModel

Collection of pool equipment objects.

from pyintellicenter import PoolModel

model = PoolModel()

# Iteration
for obj in model:
    print(f"{obj.objnam}: {obj.sname}")

# Access by object name
pump = model["PUMP1"]

# Get objects by type
bodies = model.get_by_type("BODY")
pools = model.get_by_type("BODY", "POOL")
pumps = model.get_by_type("PUMP")

# Get children of an object
children = model.get_children(panel)

# Object count
print(f"Total objects: {model.num_objects}")

PoolObject

Individual equipment item.

obj = model["PUMP1"]

# Core properties
obj.objnam     # Object name: "PUMP1"
obj.sname      # Friendly name: "Pool Pump"
obj.objtype    # Type: "PUMP"
obj.subtype    # Subtype: "VSF"
obj.status     # Status: "ON" or "OFF"
obj.parent     # Parent object name

# Type checks
obj.is_a_light              # Is this a light?
obj.is_a_light_show         # Is this a light show circuit?
obj.is_featured             # Is this marked as featured?
obj.supports_color_effects  # Supports IntelliBrite effects?
obj.is_on                   # Is status ON?

# Attribute access
rpm = obj["RPM"]
power = obj["PWR"]
temp = obj["TEMP"]

# All attributes
for key in obj.attribute_keys:
    print(f"{key}: {obj[key]}")

Discovery

Find IntelliCenter units on your local network using mDNS/Zeroconf.

from pyintellicenter import (
    discover_intellicenter_units,
    find_unit_by_name,
    find_unit_by_host,
    ICUnit,
)

# Discover all units
units = await discover_intellicenter_units(timeout=5.0)

# With existing Zeroconf instance (for Home Assistant)
from zeroconf import Zeroconf
zc = Zeroconf()
units = await discover_intellicenter_units(timeout=5.0, zeroconf=zc)

# Find specific unit
unit = await find_unit_by_name("My Pool", timeout=5.0)
unit = await find_unit_by_host("192.168.1.100", timeout=5.0)

# ICUnit properties
unit.name      # Friendly name

unit.port      # TCP port (6681)
unit.ws_port   # WebSocket port (6680)
unit.model     # Model info (if available)

# Available effects for IntelliBrite/MagicStream lights
LIGHT_EFFECTS = {
    "PARTY": "Party",
    "ROMAN": "Romance",
    "CARIB": "Caribbean",
    "AMERCA": "American",
    "SSET": "Sunset",
    "ROYAL": "Royalty",
    "BLUER": "Blue",

Connection Behavior

Connection Flow

1. Connect: Establishes TCP or WebSocket connection
2. Initialize: Fetches system info and all equipment objects
3. Monitor: Receives real-time NotifyList push updates
4. Keepalive: Sends queries every 90 seconds (configurable)

Reconnection Strategy

1. Debounce: 15-second grace period before marking disconnected
2. Exponential Backoff: Starts at 30s, doubles each attempt (max 5 min)
3. Circuit Breaker: After 5 consecutive failures, pauses for 5 minutes
4. Reset: Successful connection resets failure counters

Notification Processing

• Push notifications are queued (default: 100 items max)
• Queue prevents slow callbacks from blocking I/O
• When full, oldest notifications are dropped (prefers fresh state)
• Both sync and async callbacks are supported

Error Handling

from pyintellicenter import (
    ICError,           # Base exception
    ICConnectionError, # Connection failures
    ICResponseError,   # Bad response from IntelliCenter
    ICCommandError,    # Command execution error
    ICTimeoutError,    # Request timeout
)

try:
    await controller.start()
except ICConnectionError as e:
    print(f"Connection failed: {e}")
except ICTimeoutError as e:
    print(f"Request timed out: {e}")
