Steps
Install the meross-iot Python library (albertogeniola/MerossIot) and authenticate a MerossHttpClient with your Meross cloud account credentials.
Create a MerossManager from the HTTP client and run device discovery to populate the device list.
Filter for the garage opener using the GarageOpenerMixin device class (or by device_type="msg100").
Call the mixin's async open/close methods on the device to actuate the door, and read its reported state.
For local/offline control instead of the cloud library, use the community Meross LAN Home Assistant integration, which talks to the device over the local network.
Known gotchas
The MSG100 only pulses a relay to simulate a wall-button press; reported state comes from a separate magnetic contact sensor and can only distinguish closed vs. not-closed.
The official cloud library requires a Meross account and internet connectivity; Meross itself does not publish a local-only API (Meross LAN is a reverse-engineered community project).
