Power Pet Door Python Library

A Python library for communicating with Power Pet Door WiFi-enabled pet doors made by High Tech Pet.

Disclaimer

This library is NOT authorized, endorsed, or supported by High Tech Pet Products, Inc.

This is an independent, community-developed project. No contributions, financial or otherwise, have been received from High Tech Pet. If you need official support for your Power Pet Door, please contact High Tech Pet directly.

Installation

pip install pypowerpetdoor

Requires Python 3.11-3.14. Supported platforms: Linux and macOS. The library itself has no platform-specific code, but the simulator's plain-stdin prompt fallback uses loop.add_reader() on stdin, which Windows' ProactorEventLoop does not implement, and CI runs on Linux only - so Windows is not a claimed platform.

Quick Start

The library provides two interfaces:

PowerPetDoor (Recommended)

A high-level, Pythonic interface with cached state and simple methods:

import asyncio
from powerpetdoor import PowerPetDoor


async def main():
    door = PowerPetDoor("192.168.1.100")
    await door.connect()

    # Read state via properties
    print(f"Door status: {door.status.name}")
    print(f"Battery: {door.battery_percent}%")

    # Control via async methods
    if door.is_closed:
        await door.open()

    await door.set_hold_time(15)
    await door.set_inside_sensor(True)

    # Register callbacks
    door.on_status_change(lambda s: print(f"Status: {s.name}"))

    await door.disconnect()


asyncio.run(main())

See docs/door.md for complete documentation.

PowerPetDoorClient (Low-Level)

For advanced use cases requiring direct protocol access:

import asyncio
from powerpetdoor import PowerPetDoorClient, CONFIG, CMD_GET_SETTINGS


async def main():
    loop = asyncio.get_running_loop()

    client = PowerPetDoorClient(
        host="192.168.1.100", port=3000, keepalive=30.0, timeout=10.0, reconnect=5.0, loop=loop
    )

    await client.connect()

    settings = await client.send_message(CONFIG, CMD_GET_SETTINGS, notify=True)
    print(f"Settings: {settings}")

    client.stop()


asyncio.run(main())

See docs/client.md for complete documentation.

Documentation

Door Simulator

The library includes a full-featured door simulator for testing without hardware:

# Run interactive simulator (also available as the ppd-simulator entry point)
python -m powerpetdoor.simulator

# Run with a test script (built-in name or file path)
python -m powerpetdoor.simulator --script basic_cycle

# Run in CI/CD (exit on completion; exit code reflects pass/fail)
python -m powerpetdoor.simulator --script full_test_suite --oneshot

See docs/simulator.md for complete documentation.

Schedule Utilities

The library includes utilities for working with Power Pet Door schedules:

from powerpetdoor import (
    compress_schedule,
    validate_schedule_entry,
    compute_schedule_diff,
    schedule_template,
)

# Validate a schedule entry
entry = {...}
if validate_schedule_entry(entry):
    print("Entry is valid")

# Compress multiple schedule entries
compressed = compress_schedule(schedule_list)

# Compute differences between schedules
to_delete, to_add = compute_schedule_diff(current, new)
