hhc-n818op-plugins 0.2.0

Plugins devices IOT for Server HHC-N818OP Standalone with Python

hhc-n818op-plugins

Python plugin package for IoT devices used by HHC-N818OP Standalone.

This repository contains device adapters that extend the standalone daemon through Python entry points. At the moment, the project provides plugins for:

• Athom Smart Home devices over HTTP
• Meross devices over MQTT (via meross-iot)

Project Status

• Python package metadata is defined in pyproject.toml.
• Plugin discovery is configured through the daemon_hhc_n818op.plugins entry-point group.
• The tests/ folder currently contains only package scaffolding.

Requirements

• Python >=3.10,<3.14
• uv (recommended for dependency and virtualenv management)
• Access to the companion project hhc-n818op-standalone (declared as a direct dependency)

Installation

1) Clone the repository

git clone <your-fork-or-origin-url>
cd hhc-n818op-plugins

2) Install dependencies

uv sync

If you prefer editable installation with pip:

python -m pip install -e .

Quick Start

Install from PyPI (when available)

pip install hhc-n818op-plugins

Install from source (development mode)

git clone <your-fork-or-origin-url>
cd hhc-n818op-plugins
pip install -e .

Verify installation

python -c "from daemon_hhc_n818op.plugins.athom import PluginAthomSmartHome; print('✓ Athom plugin loaded')"
python -c "from daemon_hhc_n818op.plugins.meross import PluginMeross; print('✓ Meross plugin loaded')"

Development Workflow

Common targets are available in Makefile:

• make dev - install and validate toolchain versions
• make style - run formatting (isort, black)
• make checks - run static analysis (ruff, flake8, pylint, mypy, bandit)
• make tests - run unit-test selection (not integration_tests)

You can also run commands directly with uv:

uv run pytest -v
uv run ruff check daemon_hhc_n818op tests
uv run black --check daemon_hhc_n818op tests

Plugin Layout

Athom plugin

• Main implementation: daemon_hhc_n818op/plugins/athom/athom_smart_client_home_http.py
• Class: PluginAthomSmartHome
• Behavior:
  • Checks relay status over HTTP
  • Toggles relay state
  • Disables itself when host/network or payload errors are detected

Meross plugin

• Main implementation: daemon_hhc_n818op/plugins/meross/meross_client_cloud_mqtt.py
• Class: PluginMeross
• Behavior:
  • Authenticates through Meross cloud credentials/profile
  • Initializes MerossManager
  • Discovers devices and controls switch state
  • Persists profile/registry credential artifacts in the plugin folder

Configuration Notes

Meross plugin uses JSON files located under daemon_hhc_n818op/plugins/meross/, including:

• meross_profile.json
• meross_registry.json
• meross_cloud_credentials.json

Keep these files sanitized and avoid committing real secrets.

Packaging
