Overview

This topic aims to standardize the interaction logic for key data points (DPs) between the robot vacuum device and the control panel (Universal Base Station All-in-one MiniApp), ensuring the proper implementation of device functions and consistency in user experience.

Core functional modules

Basic control features

Cleaning control: Start/stop cleaning, pause/resume operations.
Recharge management: Automatically control recharge and monitor the states.
Mode switching: Seamlessly switch between multiple cleaning modes.
Status monitoring: Report various device states in real time.

Supported cleaning modes

Quick mapping: Intelligent path planning for comprehensive area mapping.
Full-house cleaning: Intelligent path planning for comprehensive area cleaning.
Selected area cleaning: Precise cleaning based on designated rooms.
Selected zone cleaning: Custom rectangular area cleaning.
Selected spot cleaning: Precise positioning with the "point and go" feature.
Other modes: Remote control mode and other extended functionalities.

Smart monitoring

Fault diagnosis: Simultaneous reporting and identification of multiple faults.
Live video: Audio/video monitoring on/off control.

DP definition

DP ID	DP name	Identifier	Data transfer	Data type	DP property
1	Cleaning switch	switch_go	Send and report (read-write)	Bool	`true`: Start cleaning. `false`: Stop cleaning.
2	Pause or continue	pause	Send and report (read-write)	Bool	`true`: Pause the current work state. `false`: Continue the current work state.
3	Recharge switch	switch_charge	Send and report (read-write)	Bool	`true`: Start recharge. `false`: Stop recharge.
4	Mode	mode	Send and report (read-write)	Enum	Default values (Do not modify or delete, as this might affect the control panel logic): `smart`: Automatic cleaning mode / Full-house cleaning mode. `chargego`: Automatic recharge mode (must be compatible with `goto_charge`). `zone`: Selected zone cleaning mode / Rectangular zone cleaning mode. `pose`: Point and go mode / selected spot cleaning mode. `select_room`: Selected area cleaning mode. `manual`: Remote control mode. `quick_mapping`: Quick mapping mode.
5	Status	status	Report only (read-only)	Enum	Default values (Do not modify or delete, as this might affect the control panel logic): `standby`: Standby. `smart`: Automatic cleaning in progress. `zone_clean`: Selected zone cleaning in progress. `part_clean`: Partial cleaning in progress. `cleaning`: Cleaning in progress (Alternative). `paused`: Paused. `goto_pos`: Going to the target location. `pos_arrived`: Target location reached. `pos_unarrive`: Target location unreachable. `goto_charge`: Looking for a charging dock. `charging`: Charging in progress. `charge_done`: Charging completed. `sleep`: Sleep mode. `select_room`: Selected area cleaning in progress. `seek_dust_bucket`: Looking for a dust collection bin. `mapping`: Mapping in progress. `relocation`: Relocating while cleaning. `breakpoint_charging`: Charging in progress (resuming from a previous point). `manual_control`: Remote control in progress. `mapping_done`: Mapping completed. `relocation_recharge`: Relocating to recharge. `collecting_dust`: Collecting dust (Other status values can be added after this).
28	Fault reporting	total_error	Send and report (read-write)	Raw	All faults are represented using the raw data type, without distinguishing between machine faults or base station faults. Each fault is represented by 1 byte. If faults 1, 2, and 3 occur simultaneously, the representation will be: `010203`. The panel needs to determine and separate each fault byte. If there are no faults, the value is `00`.
45	Live video switch	live_video_switch	Send and report (read-write)	Bool	`true`: Enable. `false`: Disable.

Stop pushing audio/video stream data:

Send: DP45=false
Report: DP45=false. Stop placing data into the ring buffer.

Video monitoring logic

Conditional checks:

When DP45 = false: Show a dialog: Live video not enabled.
When DP45=true:
With password: Perform password verification.
Without password: Directly open the video monitoring interface.

Things to note

The content above is based only on the Universal Base Station All-in-one MiniApp and describes the DP interactions related to robot vacuum movement. For other DP interactions, refer to the corresponding SDK demo.
Fault codes are parsed by the panel, and multiple faults might exist simultaneously.
Default enumeration values must not be modified or deleted, ensuring the control panel logic functions correctly.
Status and mode enumerations can be extended in the future (contact the Tuya product manager), but backward compatibility must be maintained.
