Nibe heatpump communication library
Decision gist · record as of 2026-08-14
Yes, if you own a supported Nibe heatpump and need programmatic control or monitoring. The library is actively maintained, has no security vulnerabilities, installs cleanly, and supports modern Python versions (3.9–3.14). The copyleft license (LGPL 3) is standard for open-source projects and poses no barrier to personal or commercial use as long as you comply with derivative-work obligations. The main prerequisite is having the appropriate hardware gateway or Modbus interface; without it, the library cannot communicate with your heatpump.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a Nibe heatpump with appropriate connection hardware (NibeGW gateway, Modbus interface, or serial adapter) and network/serial connectivity to the device.
- Low install friction with a pure-Python wheel.
- Actively maintained with a recent release (13 days old) and active repository status.

What it is and what it does
Nibe is an async Python library for reading and controlling Nibe heatpumps over three connection protocols: RS485 via a NibeGW gateway (UDP-based), TCP Modbus (for S series models), and serial Modbus (for NIBE MODBUS 40). It abstracts heatpump communication into a model-aware interface where you instantiate a HeatPump object for your specific model (F370, S320, VVM225, etc.), initialize it, subscribe to coil update events, and then read or write individual parameters called coils through a connection object.
The library handles the low-level protocol details—packet construction, Modbus framing, UDP relay through NibeGW—so you work with named coils like 'bt50-room-temp-s1-40033' rather than raw registers. It depends on construct for binary parsing, async_modbus for Modbus protocol, tenacity for retry logic, and async_timeout for timeout management. The code is production-stable, actively maintained, and carries no known vulnerabilities.
Use it for
- Monitor heatpump operating parameters (temperatures, flow rates, power consumption) in real time via event subscription.
- Integrate Nibe heatpump control into home automation systems (e.g., OpenHab, Home Assistant) over local network.
- Read and adjust heatpump settings (setpoints, operating modes) programmatically via Modbus or NibeGW.
- Log heatpump telemetry to a database or time-series system for performance analysis and diagnostics.
- Build custom dashboards or alerting systems that react to heatpump state changes.
