python-stiebel-eltron

Python API for interacting with the STIEBEL ELTRON ISG web gateway via modbus for controlling integral ventilation units and heat pumps.

This module is based on the STIEBEL ELTRON modbus user manual, but is not official, developed, supported or endorsed by Stiebel Eltron GmbH & Co. KG. For questions and other inquiries, use the issue tracker in this repo please.

Requirements

You need to have Python installed.

STIEBEL ELTRON Internet-Service Gateway ISG WEB with enabled modbus module
- You can call the STIEBEL ELTRON support, if your ISG does not have the modbus module enabled. They upgraded mine for free.
STIEBEL ELTRON heatpumpt (compatible). Successfully used devices:
- LWZ504e
- LWZ304
Network connection to the ISG WEB

Installation

The package is available in the Python Package Index.

    $ pip install pystiebeleltron

Example usage of the module

The sample below shows how to use this Python module (api for wpm heat pumps).

The API takes a ModbusUnit. You own the connection: build it, hand a unit to the API, and close it when done. Building it performs no I/O — the first read establishes the link, and a link that drops later is re-established on the next request, over the same unit handle. Each register block is a component exposed on the API, and values are read as typed attributes (None when the register is unavailable).

    import asyncio
    from modbus_connection import ModbusTcpParams
    from modbus_connection.pymodbus import ModbusConnection
    from pystiebeleltron.wpm import WpmStiebelEltronAPI

    async def main():
      connection = ModbusConnection(ModbusTcpParams(host='IP_ADDRESS_ISG', port=502))
      api = WpmStiebelEltronAPI(connection.for_unit(1))

      await api.async_update()

      print(f"outside temperature: {api.system_values.outside_temperature}")
      print(f"water comfort target temperature: {api.system_parameters.comfort_temperature}")

      # Writing a register:
      await api.system_parameters.write("comfort_temperature", 50)

      await connection.close()

    asyncio.run(main())
