Pet Camera Configurations

Last Updated on : 2022-11-24 09:20:12download

This topic describes the pet camera configurations for smart pet feeders. Built on top of the IP camera (IPC), the pet camera enables features including feeding schedule, manual feeding, feeding record, and voice message recording.

Create a product

Go to Tuya IoT Development Platform > Product > Tuya OS > Development, and click Create > Standard Category > IP Camera > Smart Camera > Custom Solution. Then, complete the required product information. The platform will automatically generate a product IP (PID).

For more information about product creation, see Create Products.

Standard function

You can select the standard function as needed. The icon of the selected function will be displayed on the control panel and device setting page in the mobile app.

Motion detection

The DP definitions are described in the following table.

DP name	Identifier	Data transfer type	Data type	Property	Remarks
DP 115 Motion detected	movement_detect_pic	Report only (read-only)	Raw	N/A	For more information about the DP implementation, see Motion detection (general).
DP 134 Motion alert	motion_switch	Send and report (read-write)	Boolean	N/A	N/A

DP 134 controls the motion detection switch. When moving objects are detected, the SDK and DP 115 are used to report the motion detection images. The user can then receive and view the motion alerts on the Message tab of the app. The motion alerts need to be configured in Device Notification. DP 115 can be replaced with DP 185.

Others

You can add more standard functions. For more information, see IPC Basic Configurations.

Custom function

The features including feeding schedule, manual feeding, feeding record, and voice message recording are custom functions. You need to manually configure the DPs to implement these features on the app. For more information, see Custom Function.

Pet Camera Configurations

Manual feeding

The DP definitions are described in the following table.

DP name	Identifier	Data transfer type	Data type	Property	Remarks
Send feeding	feed_publish	Send only (write-only)	Value	Value range: `1` to `20` Pitch: `1` Scale: `0` Unit: servings	Send the DP to define the number of servings for feeding.
Report feeding	feed_report	Report only (read-only)	Value	Value range: `0` to `20` Pitch: `1` Scale: `0` Unit: servings	Description of return values: `0`: failed to feed. `1` to `20`: the number of servings. For example, if the sent DP defines three servings and all of them are delivered, the value `3` is returned, and the app shows that feeding is successful.
Weight per serving	food_weight	Report only (read-only)	Value	Value range: `1` to `100` Pitch: `1` Scale: `1` Unit: g	The weight of food to be delivered per serving. Unit: g.

Fed successfully

Failed to feed

Feeding record

The DP definitions are described in the following table.

DP name	Identifier	Data transfer type	Data type	Property	Remarks
Feeding record	history_data	Send and report (read-write)	Boolean		Add this DP to show the Record icon.
Report feeding	feed_report	Report only (read-only)	Value	Value range: `0` to `20` Pitch: `1` Scale: `0` Unit: servings	Description of return values: `0`: failed to feed. `1` to `20`: the number of servings. For example, if the sent DP defines three servings and all of them are delivered, the value `3` is returned, and the app shows that feeding is successful.

Control with the app:

Tap the Record icon to view the feeding records. The feeding statistics can be calculated by day, week, and month.

These records are reported by the DP identifier feed_report. You need to contact Tuya’s project manager to add this identifier to implement the statistics.

Voice message recording

The DP definitions are described in the following table.

DP name	Identifier	Data transfer type	Data type	Property	Remarks
Voice message recording	feed_voice_record	Send and report (read-write)	Enumeration	Enum values: `0` and `1`	`1`: enable recording `0`: disable recording

Control panel

Feeding schedule

Two types of feeding schedules are supported: online and offline. Their differences are described as follows:

Online feeding schedule: The device needs to be connected to the internet. This feature is controlled with the identifiers feed_puslish and feed_report.
Offline feeding schedule: The device does not require access to the internet, but needs to be powered by batteries. In the case of network failure or power failure, the microcontroller unit (MCU) drives the motor to run feeding schedules.

Description of offline feeding schedule

The DP definitions are described in the following table.

DP name	Identifier	Data transfer type	Data type	Property	Remarks
Schedule	schedule	Send and report (read-write)	String		The panel represents a command with 15 bytes, converts the command into the string type, and then sends it to the device. The first 9 bytes are valid bytes and the last 6 bytes are `000000`.

After the command arrives, the device processes its format first: byte2 to byte8 are converted into decimal integers and byte0 to byte1 are converted into hexadecimal numbers.

These bytes are described in the following table.

Field	Property	Description
byte0 to byte1	Week	Treat byte0 to byte1 as a byte in the hexadecimal format and parse the bits of the byte.
byte2 to byte3	Hour	Byte2 × 10 + byte3.
byte4 to byte5	Minute	Byte4 × 10 + byte5.
byte6 to byte7	Number of servings	A value from `01` to `20` represents the number of servings.
byte8	Task on/off	`1`: The task is valid. `0`: The task is invalid.
byte9	Reserved	0
byte10	Reserved	0
byte11	Reserved	0
byte12	Reserved	0
byte13	Reserved	0
byte14	Reserved	0

byte0 to byte1 are described in the following table.

bit0	bit1	bit2	bit3	bit4	bit5	bit6
Sunday	Monday	Tuesday	Wednesday	Thursday	Friday	Saturday

bit0 to bit6 represent each day in a week from Sunday to Saturday. The task is run on the day with the bit value of 1.
If all bits are 0, the task is run only once.

Example:

Send the following command to the device:
002325121000000

00: only once
23: the hour number 23
25: the minute number 25
12: 12 servings
1: valid task
000000: reserved, unused

Meaning: 12 servings are delivered at 23:25 on the current day.

Panel design

Open the product development wizard and go to the Device Interaction step.
Select Panel Control > All-in-One Panel > IPC General Panel (App minimum version 3.17.0).

Hardware development

The IPC SDK must be integrated to implement a pet camera. Perform the following steps:

Check if the SDK for your cross-compilation toolchain in use is available. You can download it from GitHub. If you do not find the required SDK, contact the project manager and request the SDK.
Develop with the SDK as instructed by the IPC SDK Development Guide.

Push notification settings

You can set rules to trigger an automated push notification. For example, set a threshold for a function. If the preset value is reached, the user will receive an alert from the mobile phone.

The following figure shows how to access push notification settings on the Tuya IoT Development Platform:

Push notification is available to accounts of the premium version or ultimate version.

Configure the push notification as needed and adapt to the firmware. After you finish the configuration, contact the project manager for approval. For more information, see Configure Push Notification.

Successful manual feeding (DP feed_report)

Failed manual feeding (DP feed_report)

Insufficient food (DP realtime_data)

The custom DP definitions are described in the following table.

DP name	Identifier	Data transfer type	Data type	Property	Remarks
Real-time data	realtime_data	Send and report (read-write)	Enumeration	Enum values: `0` and `1`	`1`: An error has occurred while dispensing food. `0`: The remaining food is insufficient.

Examples of trigger conditions
