Direction: cloud → client.

Sber Smart Home requests from the agent app the current state of devices. The agent shall respond by sending the following message: sberdevices/v1/<username>/up/status.

Use case example:

1. The user manually changes the state of any devices E.g. turns off a lamp.
2. From time to time, the Smart Home requests from the agent app installed on the controller the current state of the user's devices.
3. The agent receives from the controller the current state of devices, including that of the light. Then it sends the following message: sberdevices/v1/<username>/up/status.
4. Sber Smart Home updates the light state in the Salute app, on SberPortal, SberBox and other devices with Salute assistant.
