python installation script does not work

[fconrotte]

Hello guys !

Thank you for opening your API !

I installed your Homewizard P1 dongle on my electricity digital meter.

I live in Belgium and I'm trying to figure out why my electricity provider seems to overcharge how many kwh I use per day.

I would simply want to fetch every day at midnight the following values
energy_import_t1_kwh
energy_import_t2_kwh
energy_import_t3_kwh
energy_import_t4_kwh
energy_export_t1_kwh
energy_export_t2_kwh
energy_export_t3_kwh
energy_export_t4_kwh

So I followed your procedure:
python3 -m pip install python-homewizard-energy

and ran the provided code

import asyncio
from homewizard_energy import HomeWizardEnergyV1
IP_ADDRESS = "192.168.1.123"
async def main():

    async with HomeWizardEnergyV1(host=IP_ADDRESS) as api:

        # Get device information, like firmware version
        print(await api.device())

        # Get measurements, like energy or water usage
        measurement = await api.measurement()
        print(measurement.energy_import_kwh)

        # Example of getting raw telegram data
        telegram = await api.telegram()
        print(telegram)  # Raw P1 meter data

        # Get all data and remap v1 data to new v2 structure
        print(await api.combined())

        # Turn on the Energy Socket outlet
        await api.state(power_on=True)
    asyncio.run(main())

But it does not work

File "C:\Users\FredericConrotte\p1.py", line 2, in <module> from homewizard_energy import HomeWizardEnergyV1 ImportError: cannot import name 'HomeWizardEnergyV1' from 'homewizard_energy'

The problem is that the pip install does not include the v1 and v2 subfolders found in your source code:
https://github.com/homewizard/python-homewizard-energy/tree/main/homewizard_energy

Can you help me ?

Hi @fconrotte! Thank you for reporting!

I’ve tried to reproduce your issues, but it works on my machine. The error you get is what would happen when homewizard_energy was not installed. My suggestion would be to follow some troubleshooting steps in that direction.

I suspect that pip tried to install the package for a different Python version. Maybe some of the following things could work:

• Run python3 -m pip install python-homewizard-energy
• or run python3 -m pip3 install python-homewizard-energy
• Run pip freeze, you should see python-homewizard-energy==....
• Do some checks with python --version and pip --version (or python3/pip3)

Strangely, now it works as well. Tested on Windows 11 with Python 3.13

Thanks !
