BASTION Device Compatibility Checker

Check if your home security devices are compatible before you buy. 403 devices across 45 manufacturers with 79 field-tested compatibility overrides. Frequency matching, protocol validation, and known edge cases — so you don't find out after the install.

Built on a decade of home security industry experience.

Part of the BASTION portfolio.

Use It Online

No install needed. Open in your browser, pick two devices, get your answer:

bastion-compat-check.onrender.com

No data stored. No accounts. No tracking. Compatibility checks run in memory and return a result — nothing is logged.

---

Run It Locally (Complete Privacy)

For maximum privacy, install and run on your own computer. No network calls, no telemetry.

Install

Requires Python 3.12+.

pip install bastion-compat-check

Launch the Web Interface

flask --app src.bastion_compat.web:create_app run

Opens the same interface — running entirely on your machine.

What It Does

Select two devices — a panel and a sensor (or peripheral) — and get an instant compatibility verdict:

Verdict	Meaning
COMPATIBLE	Devices work together. Frequency and protocol confirmed.
INCOMPATIBLE	Devices will not work together.
PARTIAL	Devices can connect but with limitations (e.g., reduced feature set).
UNKNOWN	Not enough data to determine compatibility.

Features

• Two-device compatibility check — select any two devices and get an instant verdict with explanation
• Single-device mode — select one device to see everything compatible with it
• Browsable device database — filterable table of all 403 devices
• Dynamic alternatives — incompatible verdicts suggest compatible alternatives
• Search-as-you-type — find devices by manufacturer, model, or type

Device Database

403 devices across 45 manufacturers with 79 compatibility overrides.

Top manufacturers: Honeywell (59), 2GIG (47), Frontpoint (39), Interlogix/GE (34), Resolution Products/Alula (34), Ring (16), SimpliSafe (16), Alarm.com (16), Vivint (14), DSC (12), Elk Products (12), Yale (11), Abode (10), Qolsys (9), Cove (9), ADT (5), and 29 more.

Peripheral categories: Smart locks, thermostats, cameras, garage controllers, water valves, sirens, keypads, Z-Wave switches/dimmers, repeaters, receivers, and translators.

Database grows via community contribution. See Contributing Device Data below.

How It Works

The rules engine evaluates devices in priority order:

1. Explicit overrides — field-tested compatibility data takes precedence over rules
2. Frequency match — sensor RF frequency must match the panel's receiver
3. Protocol match — Z-Wave to Z-Wave, proprietary RF to proprietary RF
4. Partial compatibility — Z-Wave Plus device on a Z-Wave (non-Plus) controller
5. Platform dependency — flags when a device requires a specific monitoring platform

No AI, no cloud, no network calls. Pure rule evaluation against a curated device database.

Development

git clone https://github.com/Pachacutie/bastion-compat-check.git
cd bastion-compat-check
python -m venv .venv
source .venv/bin/activate  # or .venv\Scripts\activate on Windows
pip install -e ".[dev,web]"
pytest -v

Contributing Device Data

Edit the JSON files in data/ and submit a PR:

• panels.json — control panels and hubs
• sensors.json — door/window, motion, glass break, smoke, CO, flood, etc.
• peripherals.json — locks, thermostats, garage controllers, cameras, water valves
• overrides.json — known edge cases that rules alone can't catch

Each entry follows a strict JSON schema. See existing entries for format.
