Trigger mechanism:

The quantity limits of the mentioned items are interrelated. It is possible that the upper limit of item B is triggered before the upper limit of item A is reached. Therefore, the principle of the first trigger will be applied to all limits.

Scope of Quantity Limitations:

The quantity restrictions apply to the Tuya Smart App, Smart Life App, OEM App, and App SDK.

Note: Items such as number of homes, number of home members, number of rooms, number of room devices, number of device group devices, number of home device groups, number of users in device group sharing, number of users in device sharing, number of joined homes, and MQTT message length are still in the gray release phase and may be subject to elastic adjustment. Tuya reserves the right to interpret these requirements.
