Tuya Smart Home

Control any Tuya/Smart Life device via cloud API or local network.

Dependencies

pip3 install tinytuya tuya-connector-python

Configuration

Two control modes available:

Cloud Mode

Requires Tuya IoT Platform credentials from https://iot.tuya.com:

• ACCESS_ID — from Cloud Project
• ACCESS_SECRET — from Cloud Project
• REGION — cn (China), us (Americas/SEA), eu (Europe), in (India)

Local Mode (Recommended)

Requires device info (obtain via cloud API first):

• DEVICE_ID — device identifier
• LOCAL_KEY — device encryption key
• IP — device local IP address
• VERSION — protocol version (usually 3.4)

Quick Start

Scan for devices on local network

python3 scripts/tuya_scan.py

Get device info (cloud)

python3 scripts/tuya_control.py --mode cloud --action info \
  --device-id DEVICE_ID \
  --access-id ACCESS_ID --access-secret ACCESS_SECRET --region cn

Query device status

# Cloud
python3 scripts/tuya_control.py --mode cloud --action status \
  --device-id DEVICE_ID \
  --access-id ACCESS_ID --access-secret ACCESS_SECRET --region cn

# Local
python3 scripts/tuya_control.py --mode local --action status \
  --device-id DEVICE_ID --ip IP --local-key KEY

Common Device Commands

China Region Note

China data center (openapi.tuyacn.com) blocks non-China IPs by default.

Solutions:

1. Add your IP to whitelist in Tuya IoT Platform → Project → IP Whitelist
2. Use local mode (bypasses cloud entirely, recommended)
