You’re right, Meross isn’t building the integration themselves, that’s our responsibility in this case. Meross is, however, providing the APIs and documentation we need to interface with their devices.
Right now, we’re working on ensuring that the official app:
- Lists all currently available Matter devices, and
- Supports the first two devices on their new cloud API: the MSG100 and MSG200 garage door openers.
A sneak peek:
Other devices aren’t yet available through their API, but Meross has assured us that support will be expanded in the future.
To recap: Homey is developing the official integration, while Meross provides the APIs and documentation needed to make it possible
