Home Automation Device Compatibility Checker
Check whether two smart home devices are compatible based on communication protocol, voltage, frequency, and hub/bridge requirements.

Formulas Used
Overall Compatibility Score:
Score = 0.35 × Protocol + 0.25 × Voltage + 0.15 × Frequency + 0.10 × Hub + 0.15 × Load
Voltage Compatibility:
VoltageDiff% = |V_A − V_B| / ((V_A + V_B) / 2) × 100
Score = 100 if 0%, 70 if ≤ 10%, 0 if > 10%
NEC 80% Electrical Load Rule:
Safe Capacity (W) = Breaker Rating (A) × Voltage (V) × 0.80
Total Load (W) = Existing Load + Power_A + Power_B
Assumptions & References
- Protocol compatibility scores are based on published interoperability standards and common hub/bridge solutions (Zigbee Alliance, Z-Wave Alliance, CSA Matter specification).
- Voltage tolerance of ±10% follows IEC 60038 standard voltage tolerances for household equipment.
- The NEC 80% continuous load rule is per NFPA 70 National Electrical Code, Article 210.20.
- Matter and Thread are treated as natively compatible per the Connectivity Standards Alliance (CSA) specification.
- Frequency mismatch scoring assumes modern switch-mode power supplies (SMPS) rated 50/60 Hz; motor-driven devices may be incompatible.
- Hub compatibility assumes a single multi-protocol hub (e.g., Home Assistant, SmartThings) can bridge supported protocols.
- This tool provides guidance only; always consult device datasheets and a licensed electrician for installation.
