I put a lot of time into this project. If you like it, you can support me with a donation.

Getting started

pip install keba-keenergy-api

Usage

import asyncio
from typing import Any

from keba_keenergy_api import KebaKeEnergyAPI
from keba_keenergy_api.constants import HeatCircuit
from keba_keenergy_api.constants import HeatCircuitOperatingMode

async def main():
    client = KebaKeEnergyAPI(
        host="ap4400.local",
        username="test",
        password="test",
        ssl=True,
        skip_ssl_verification=True
    )

    # Get current outdoor temperature
    outdoor_temperature = await client.system.get_outdoor_temperature()

    # Get heat circuit temperature from heat circuit 2
    heat_circuit_temperature = await client.heat_circuit.get_target_temperature(
        position=2
    )

    # Read multiple values
    data = await client.read_data(
        request=[
            HeatCircuit.TARGET_TEMPERATURE,
            HeatCircuit.TARGET_TEMPERATURE_DAY
        ],
        extra_attributes=True
    )

    # Enable "day" mode for heat circuit 2
    await client.heat_circuit.set_operating_mode(
        mode=HeatCircuitOperatingMode.DAY.value,
        position=2
    )

    # Write multiple values
    await client.write_data(
        request={
            # Write heat circuit on position 1 and 3
            HeatCircuit.TARGET_TEMPERATURE_DAY: (20, None, 5),
            # Write night temperature on position 1
            HeatCircuit.TARGET_TEMPERATURE_NIGHT: (16,),
        },
    )

asyncio.run(main())

By default, the library creates a new connection to KEBA KeEnergy API with each coroutine. If you are calling a large number of coroutines, an aiohttp ClientSession() can be used for connection pooling:

import asyncio

from keba_keenergy_api import KebaKeEnergyAPI

from aiohttp import ClientSession

async def main():
    async with ClientSession() as session:
        client = KebaKeEnergyAPI(
            host="ap4400.local",
            username="test",
            password="test",
            ssl=True,
            skip_ssl_verification=True,
            session=session
        )
        ...

asyncio.run(main())

⚠️ Write warnings

This is a low-level API that allows writing values outside the safe operating range. Improper use can damage heating systems and hardware. Always check the attributes, as these may contain minimum and maximum values.

Use at your own risk!

Example:

The upper limit from the hot water tank temperature is 52 °C. Do not write larger values under any circumstances, even if it would be possible.

{
    "name": "APPL.CtrlAppl.sParam.hotWaterTank[0].param.normalSetTempMax.value",
    "attributes": {
        "dynUpperLimit": 1,
        "formatId": "fmtTemp",
        "longText": "Temp. nom.",
        "lowerLimit": "0",
        "unitId": "Temp",
        "upperLimit": "52"
    },
    "value": "50"
}

And one last warning:

Attention! Writing values should remain within normal limits, as is the case with typical use of the Web HMI. Permanent and very frequent writing of values reduces the lifetime of the built-in flash memory. Be carefully!
