Tuya Wi-Fi & Bluetooth Smart Indoor Planter Lite

English | 中文

Overview

The demo lets you easily build a smart indoor garden and connect it to the Tuya IoT Platform. With the Tuya Smart app, you can control this garden and monitor plants anytime. The demo describes the development process and provides a material list, circuit diagram, and complete code. You can build a smart garden with the WB3S module and connect it to the Tuya IoT Platform to achieve the following functions:

• Remote control with an app.
• Dim the warm white and multi-color grow light.
• Self-watering and scheduled light filling.

Get started

Build and flash

• Download the SDK.

• Download the demo to the app folder in the SDK directory.

  $ cd apps
  $ git clone https://github.com/tuya/tuya-iotos-embeded-demo-wifi-ble-smart-planter-lite

• Execute the following command in the SDK root directory and start to build firmware.

  sh build_app.sh apps/tuya-iotos-embeded-demo-wifi-ble-smart-planter-lite tuya-iotos-embeded-demo-wifi-ble-smart-planter-lite 1.0.0 

• For more information about flashing and authorization, see Burn and Authorize WB Series Modules.

Entry to application

Entry file: tuya_device.c

Function: device_init()

• Call tuya_iot_wf_soc_dev_init_param() for SDK initialization to configure working mode and pairing mode, register callback functions, and save the firmware key and PID.
• Call tuya_iot_reg_get_wf_nw_stat_cb() to register callback of device network status.
• Call the initialization function app_plant_init() in the application layer.

Data point (DP)

• Send DP data: dev_obj_dp_cb() -> deal_dp_proc()
• Report DP data: dev_report_dp_json_async()

Function name	OPERATE_RET dev_report_dp_json_async(IN CONST CHAR_T *dev_id,IN CONST TY_OBJ_DP_S *dp_data,IN CONST UINT_T cnt)
devid	For gateways and devices built with the MCU or SoC, the devid is NULL. For sub-devices, the devid is sub-device_id.
dp_data	The name of DP struct array
cnt	The number of elements in the DP struct array
Return	OPRT_OK: success. Other values: failure.

Pin configuration:

Light board	Water pump	Soil moisture sensor
R P24	Relay P14	ADC3 P23
G P7
B P6
W P8
