Access Control DP Reference

This topic describes the features, formats, and usages of data points (DPs) that apply to Wi-Fi access control products.

Background

Terms

The following table lists the important terminologies that you may find helpful in understanding this topic. For more information, see Glossary.

Term	Description
Data point (DP)	A DP is an abstract representation of a feature you want to apply to a physical device, which can be defined by various data types.
Product ID (PID)	A PID is an abstract representation of a collection of physical devices that have the same configurations and properties. Each product created on the Tuya Developer Platform is assigned a unique PID that is associated with the product information, including DPs, app control panel, and purchase information.
UUID	A 20-character universally unique identifier of a device, also known as a license.
AuthKey	A 32-character authkey used to register a device with cloud services. One UUID corresponds to one AuthKey uniquely.
Firmware key	The unique identity of firmware assigned by the Tuya Developer Platform.
Member	Also known as user.
Member ID	The ID of a member or a user, which is a 2-byte unsigned integer assigned and managed by the server. The valid values range from 0x0001 to 0xFFFE. The rest are reserved.
Hardware ID	The unique ID of the hardware specific to an unlocking method, which is a 2-byte unsigned integer assigned and managed by the local processor. The valid values range from 0x0000 to 0xFFFE. 0xFFFF is reserved. For example, for fingerprint unlocking and password unlocking, the hardware ID is 0x0001 and 0x0002 respectively.
Validity	A specific unlocking method (such as fingerprint and password) is valid during the specified time period.
Send	Data is sent from a mobile phone to a device.
Report	Data is sent from a device to a mobile phone.

DP format

The size of dp_data_len is two bytes for Tuya-enabled Wi-Fi access control devices. The following table details the DP format.

Field	Length (byte)	Description
dp_id	1	The ID of a DP.
dp_type	1	The data type of a DP.
dp_data_len	2	The data length of a DP.
dp_data_value	dp_data_len	The payload of a DP.

Manage unlocking methods

The unlocking methods are associated with user information, such as fingerprints, passwords, dynamic passwords, and face IDs.

Sync unlocking methods

• Purpose: To ensure the unlocking methods in the local device and the server are in sync, each time users open the lock member list or pull down to refresh the list, all the added unlocking methods will be synced between them.
• Hardware types: Used to notify the lock of what unlocking methods it should report. For the in-sync stage, the data length of each packet is defined by you. The total length of one packet should not exceed 200 bytes.
• Sync locally-added unlocking methods: A lock syncs the locally-added unlocking methods with the cloud in the following cases:
  • Use the member ID 0xFFFD to report an unlocking method. After sync, the user can associate the unlocking method with an app member.
  • Use the member ID 0xFFFF to report an unlocking method. After sync, the user can associate the unlocking method with an app member.
  • Use the user ID 0xFFFD or 0xFFFF to sync the locally-added unlocking method. The cloud handles the received data as is, without identifying the permission to delete the unlocking method using the app.

				0x01: Sync finished	Total packets For example, if a packet for the in-sync stage is delivered twice, the packets are two in total.

Manage temporary passwords

The types of temporary passwords include one-time and recurring. The temporary password is different from the ordinary password in the following ways:

• A temporary password is not associated with any members.

• The validity period of a temporary password can be modified when the lock is connected.

• As an unlocking method, the type of the temporary password is defined as 0xF0. 0x01 indicates password. 0x02 indicates door card. 0x03 indicates fingerprint.

Take care of the following possible issue with temporary passwords:

• If the lock fails to sync the internal clock with the server time due to a power failure, this can cause the schedule for recurring access to not work properly.
• Solution:
  • Add a backup battery to the lock to ensure it can still be connected to the cloud even after a power failure.
  • You can accept the problems that might arise.

Manage remote unlocking

Key configuration

• A key is required to use remote unlocking. Usually, after a successful initial pairing, the cloud will proactively send a key. Alternatively, when the MCU proactively reports DP 8 as a failure, the cloud will also issue a key. If the MCU does not receive a key after sending a request to the cloud, it can make multiple requests until the cloud issues a key.
• After receiving the data of DP 8, the MCU processes and stores the received key and reports success to the cloud. When the lock receives a remote unlocking request, it uses the locally stored key for authentication, without requesting it from the cloud again.
• The key for remote unlocking (DP 9) is configured through the command of setting keys for remote unlocking.
• In this command, validity, key ID, start time, end time, and access times are reserved fields.

Data transmission	dp_id (1 byte)	dp_type (1 byte)	dp_data_len (2 bytes)	dp_data_value
Send	8	raw	len	Validity (1 byte)	Key ID (2 bytes)	Start time (4 bytes)	End time (4 bytes)	Access times (2 bytes)	Key (8 bytes)

Report	8	raw	len	Return value (1 byte)			Key ID (2 bytes)
				0x00: Success. 0x01: Failure.			Not enabled. Only one key ID.

Remote unlocking

Remote unlocking indicates the door is unlocked through a mobile app.

• If the command is initiated by a mobile app, this is called remote unlocking by app.
• If the command is initiated by a smart speaker, this is called remote unlocking by voice.

Call, image capture, and alert settings

• Capture again: Tapping the retake button on the app panel will send the respective DP command to the device.
• Voice prompts: Configure the multi-language support by yourself. When the user declines a remote unlocking request, the app panel sends the reason for declining to the device through the respective DP. The device plays the voice prompt based on the received DP value.
• Alert dialog: When the device detects an alert, the user will be prompted to process it on the app panel. The user’s chosen action is then sent to the device via DP 39.

Algorithm-generated passwords

This section describes the offline passwords and dynamic passwords that are generated based on algorithms. How it works: The cloud and the lock run the same algorithm to generate and verify passwords. When the user enters the generated password, the lock unlocks the door if the password is verified successfully.

Offline password

• Scenarios:

  The door lock user gets an offline password from the app and notifies the visitor of this password. The offline password can be the following types:

  • One-time password: It is valid for six hours and can be used only once. If the password is used within the validity period, an unlocking record is created.
  • Timed password: It must be used once within 24 hours for activation. Otherwise, it will expire. It can be used unlimited times within the specified validity period. Every unlocking operation is recorded.
  • The code to clear a single password: It has the same validity period as the corresponding password and takes effect only on the first-time usage. A record of clearing a single password is created after the code is used.
  • The code to clear all passwords: It is a one-time clear code and valid for 24 hours. A record of clearing all passwords is created after the code is used.

• Limitations on clearing a single password or all passwords:

  • Only the activated and valid password can be cleared.
  • The one-time password cannot be cleared because it is invalid after use.

• Usage: For more information, see Serial Communication Protocol. If you develop with the SDK, see the corresponding API reference.

When the user adds or modifies unlocking methods, the recurring validity period and the access times are both applied. There are two use cases:

• When the access times are 0x00, this indicates permanent access. You only need to process the recurring pattern of the validity.
• When the recurring pattern is 0x00, this indicates one-time access. You only need to process the access times.

For example, schedule a password to be valid every Monday to Friday from 08:00 to 08:30 from 2018-01-26 08:00:00 to 2018-08-08 09:56:32. The validity is 0x ‭5A6A6F80 5B6A4DD0 02 0000003E 0800 081E‬‬‬‬‬‬.

• 2018-01-26 08:00:00 = 1516924800 (Unix timestamp) = 0x‭5A6A6F80‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬ (hex)
• 2018-08-08 09:56:32 = 1533693392 (Unix timestamp) = 0x5B6A4DD0‬ (hex)
• The recurring pattern: 0x02 indicates a weekly schedule.
• Recurring bit 1 = Recurring bit 2 = Recurring bit 3 = 0x00
• Recurring bit 4 = 0x3E (Monday to Friday)
• The start time 1 is 0x08. The start time 2 is 0x00.
• The end time 1 is 0x08. The end time 2 is 0x1E.

Appendix 2: Channel protocol

The multi-channel data format is defined as:

Total number of channels (1 byte)	Channel 1 information (1+n bytes)	…	Channel n information (1+n bytes)
0x00 to 0xFE	Channel ID + channel value	…	Channel ID + channel value

Field description:

• Total number of channels (1 byte): Indicates the number of channels in the packet.
• Current channel ID (1 byte): Starts from 0. For example, channel 1 and channel 2 correspond to the values of 0 and 1 respectively.
• The value of the current channel: See the definition of the respective DP.

Example: A scene with 4 channels, with the value of a DP being one byte.

Scenes	Value of channel 1 (1 byte)	Value of channel 2 (1 byte)	Value of channel 3 (1 byte)	Value of channel 4 (1 byte)	Data to report/send
Send the values of three channels to the device	0x21	No command to send	0x5B	0x0B	Data sent to the device: 0x03 0x00 0x21 0x02 0x5B 0x03 0x0B

Appendix 3: Always-on time periods

Each time period is four bytes in size.

• The first byte represents the hours of the start time.

• The second byte represents the minutes of the start time.

• The third byte represents the hours of the end time.

• The fourth byte represents the minutes of the end time.

  For example, if the start time is 08:30 and the end time is 20:30, the always-on time period is 0x08 0x1E 0x14 0x1E.
