HomeWizard Cloud

Async Python library for the HomeWizard Cloud API — stream your P1 meter from the cloud over WebSocket. No local device access needed.

Based on the cloud API research by Sven Serlier and the implementation in jtebbens/com.homewizard.

Install

pip install homewizard-cloud

Usage

import asyncio
from homewizard_cloud import HomeWizardCloudClient


async def main():
    client = HomeWizardCloudClient(email="you@example.com", password="secret")
    await client.authenticate()

    # Find your P1 dongle
    for device in await client.get_p1_devices():
        print(device.device_id, device.name)

    # Stream live data
    await client.listen(
        "p1dongle/5c2faf3c6a8a",
        on_state=lambda device_id, state: print("state:", state["active_power_w"]),
        on_realtime=lambda m: print("live wattage:", m.wattage),
    )


asyncio.run(main())

How it works

  1. Auth — GET api.homewizardeasyonline.com/v1/auth/account/token with HTTP Basic auth (email:password) returns an access token.
  2. Discovery — GET homes.api.homewizard.com/locations lists your homes and P1 devices (type == "p1dongle", id like p1dongle/5c2faf3c6a8a).
  3. State stream — wss://energy-app-ws.homewizard.com/ws/ sends a hello message (masquerading as the Android energy app, which the server requires), then subscribe_device. Full p1dongle states and json_patch deltas follow.
  4. Realtime stream — wss://tsdb-reader.homewizard.com/devices/date/now pushes second-by-second wattage.

Both streams auto-reconnect and the token is refreshed when the server rejects it.
