madvr-envy 2.0.0

Async Python client for madVR Envy IP Control.

madVR Envy Python Library

Spec-first async Python client for madVR Envy IP Control.

This project intentionally does not inherit implementation patterns from existing community libraries. It is being built from the official Envy IP Control specification and protocol captures.

Current API Shape

• Typed command helpers in madvr_envy.commands
• High-level async client in madvr_envy.client.MadvrEnvyClient
• Typed protocol parser in madvr_envy.protocol

Example:

import asyncio

from madvr_envy.client import MadvrEnvyClient


async def main() -> None:
    client = MadvrEnvyClient(host="192.168.1.100")
    await client.start()
    await client.wait_synced(timeout=10)

    snapshot = await client.refresh_device()
    print(snapshot.power_state, snapshot.incoming_signal, snapshot.aspect_ratio)

    await client.get_mac_address(wait_for_ack=True)
    await client.display_message(3, "Hello from py-madvr-envy")
    await client.change_option("temporary\\hdrNits", 120)

    groups = await client.enum_profile_groups_collect()
    for group in groups:
        print(group.group_id, group.name)

    await client.stop()


asyncio.run(main())

Protocol Coverage

See docs/PROTOCOL_COVERAGE.md for implemented command and notification coverage.

Enumeration Collectors

For stream enumerations, use typed collectors:

• enum_profile_groups_collect()
• enum_profiles_collect(profile_group)
• enum_setting_pages_collect()
• enum_config_pages_collect()
• enum_options_collect(page_or_path)

These helpers wait for protocol end markers and raise EnumerationTimeoutError if an end marker is not observed in time.

Runtime State

Use client.refresh_device() when an integration needs a complete, typed view of the device. The client owns the protocol request sequence for runtime telemetry, video geometry, temperatures, and profiles, then returns an EnvyDeviceSnapshot.

For lower-level streaming consumers, madvr_envy.adapter.EnvyStateAdapter converts mutable runtime state into immutable snapshots plus typed deltas/events:

You can wire this directly through the client:

from madvr_envy.adapter import EnvyStateAdapter

adapter = EnvyStateAdapter()

def on_update(snapshot, deltas, events):
    ...

handle = client.register_adapter_callback(adapter, on_update)
# later: client.deregister_adapter_callback(handle)
