Luxtronik Domoticz Plugin v2

Features

⚡

Smart COP Tracking

Separate efficiency metrics for heating, hot water, and combined — only measured during steady-state operation.

🛡

Intelligent Gating

Blocks sensor updates when the compressor is idle, preventing misleading readings from skewing your data.

🔒

Secure Write Control

All commands validated against an explicit allowlist before touching your heat pump’s EEPROM.

🔄

Multi-Instance Support

Run multiple plugin instances for homes with more than one heat pump, each fully independent.

🌐
