Tuya Cloud

Read sensor data and control Tuya IoT devices via Tuya Cloud API or local LAN. Use when the user wants to list devices, read temperature, humidity, soil moisture, battery or other sensor data, or send commands to switches and valves. Requires TUYA_ACCESS_ID, TUYA_ACCESS_SECRET, and optionally TUYA_API_ENDPOINT in .env.

Tuya Cloud Controller

Read sensor data and control Tuya IoT devices via scripts/tuya_controller.py. Supports both Tuya Cloud API and direct local LAN control.

Device registry

Known controllable devices are defined in scripts/config.py as CONTROLLABLE_DEVICES (OPTIONAL).
Always consult this list first if exist to resolve a device name to its device_id.
For valve devices the valve key gives the DP code ( e.g. switch_1) to use as the command code.
Only call tuya_list_devices if the device is not listed in the config.

Setup

Add credentials to .env:

TUYA_ACCESS_ID=your_access_id
TUYA_ACCESS_SECRET=your_access_secret
TUYA_API_ENDPOINT=https://openapi.tuyaeu.com  # default: tuyaus.com (US)

Regional endpoints: EU tuyaeu.com · US tuyaus.com · CN tuyacn.com · IN tuyain.com

Enable IoT Core service in your Tuya IoT Platform project, and grant devices controllable permission (read-only by default).

Tools

tuya_list_devices

List all Tuya devices linked to the cloud project.

python scripts/tuya_controller.py list_devices
python scripts/tuya_controller.py list_devices --output_format json --output_path devices.json

tuya_read_24h_avg

Return the 24-hour average soil moisture (humidity) for a sensor, computed from its Tuya DP log history.

python scripts/tuya_controller.py read_24h_avg <device_id>

Output is a JSON object:

{
  "avg_humidity": 34.2,   // mean of all va_humidity log entries over 24 h; null if no data
  "count": 47,            // number of log entries found
  "min_humidity": 28.0,
  "max_humidity": 41.0
}

If count is 0 all fields are null — this happens when the device has no log history yet or the Tuya logs API is rate-limited. The garden-irrigation skill falls back to the current reading in that case.

tuya_read_last_n

Return the average soil moisture from the last N humidity readings, looking back up to 7 days. Preferred over read_24h_avg — avoids pagination-related rate limiting and gives a stable average regardless of time of day.

python scripts/tuya_controller.py read_last_n <device_id>
python scripts/tuya_controller.py read_last_n <device_id> --n 100

Output is the same JSON shape as read_24h_avg:

{
  "avg_humidity": 59.3,
  "count": 50,
  "min_humidity": 46.0,
  "max_humidity": 66.0
}

If count is 0 all fields are null — rate-limited or no log history. The garden-irrigation skill falls back to the current reading in that case.

tuya_read_sensor

Read all sensor data from a Tuya device (temperature, humidity, battery, motion, door state, switch state).

python scripts/tuya_controller.py read_sensor <device_id>
python scripts/tuya_controller.py read_sensor <device_id> --output_format text

parse_sensor_data() interprets raw API keys:

Sensor	Raw keys	Notes
Temperature	va_temperature, temp_current, temp_set	Divided by 10 (e.g. 245 → 24.5°C)
Humidity	va_humidity, humidity_value	Percentage as-is
Battery	battery_percentage, battery	Good >80% / Medium >20% / Low ≤20%
Motion	pir	"pir" value = detected
Door	doorcontact_state	Boolean → Open/Closed
State	state	Boolean → On/Off
Soil moisture	soil_moisture, humidity, va_humidity	Percentage as-is

tuya_control_device

Send commands to a Tuya device (switch, valve, countdown timer). Pass a JSON array of {"code", "value"} pairs. Uses the IoT Core /v1.0/iot-03/ endpoint, which supports Zigbee sub-devices.

# Turn switch/valve on or off
python scripts/tuya_controller.py control_device <device_id> '[{"code":"switch_1","value":true}]'
python scripts/tuya_controller.py control_device <device_id> '[{"code":"switch_2","value":false}]'

# Open valve for a fixed duration — send switch ON + countdown in ONE call
# countdown_1 / countdown_2 values are in MINUTES — do NOT multiply by 60
python scripts/tuya_controller.py control_device <device_id> '[{"code":"switch_1","value":true},{"code":"countdown_1","value":10}]'

⚠️ countdown_1 / countdown_2 are in minutes. 10 = 10 min, 60 = 1 hour.

Dual-channel valve devices

Some valve devices expose two independent channels (e.g. left and right outlet). Each channel has its own switch and countdown DP:

Channel	Switch DP	Countdown DP
Left	switch_1	countdown_1
Right	switch_2	countdown_2

Control each channel independently:

# Open left valve for 5 minutes
python scripts/tuya_controller.py control_device <device_id> '[{"code":"switch_1","value":true},{"code":"countdown_1","value":5}]'

# Open right valve for 10 minutes
python scripts/tuya_controller.py control_device <device_id> '[{"code":"switch_2","value":true},{"code":"countdown_2","value":10}]'

# Close right valve immediately
python scripts/tuya_controller.py control_device <device_id> '[{"code":"switch_2","value":false}]'

To register a dual-channel valve in config.py, add both channels as separate entries or use a list:

# Option A: two entries (one per channel)
{'name': 'Greenhouse valve left',  'device_id': '<id>', 'valve': 'switch_1', 'countdown': 'countdown_1'},
{'name': 'Greenhouse valve right', 'device_id': '<id>', 'valve': 'switch_2', 'countdown': 'countdown_2'},

Local LAN Tools

Control devices directly over the local network without cloud API calls. No credentials needed for scanning; local_key and ip required for read/control.

scan_local

Scan the local network for Tuya devices via UDP broadcast.

python scripts/tuya_controller.py scan_local
python scripts/tuya_controller.py scan_local --timeout 10
python scripts/tuya_controller.py scan_local --enrich --output_format json   # add cloud names/local_keys (requires cloud credentials)

read_local

Read device status directly over LAN (no cloud round-trip).

python scripts/tuya_controller.py read_local <device_id> <ip> <local_key>
python scripts/tuya_controller.py read_local <device_id> <ip> <local_key> --version 3.4

control_local

Send commands to a device directly over LAN. Commands can use integer DP index (dp) or string DP name (code).

python scripts/tuya_controller.py control_local <device_id> <ip> <local_key> '[{"dp":1,"value":true}]'
python scripts/tuya_controller.py control_local <device_id> <ip> <local_key> '[{"code":"switch_1","value":true}]'

Use integer dp for maximum compatibility. String code requires the device to support it.

API Endpoints (internal)

• Device list: GET /v1.0/iot-01/associated-users/devices
• Device info: GET /v1.0/devices/{device_id}
• Device status: GET /v1.0/iot-03/devices/{device_id}/status
• Send commands: POST /v1.0/iot-03/devices/{device_id}/commands

Dependencies

pip install tinytuya python-dotenv

Troubleshooting

Error	Fix
"Data center is not enabled"	Enable IoT Core in Tuya IoT Platform → Service API
"Permission denied"	Subscribe to IoT Core and enable Device Status Notification
Device offline	online: false; soil moisture returns null
Wrong endpoint	Match TUYA_API_ENDPOINT to your account region
Local scan finds nothing	Check firewall; UDP broadcast may be blocked on some networks
Local control fails for Zigbee devices	read_local / control_local CLI commands do not support Zigbee sub-devices. Use the Python API directly: get_local_subdevice_status(gateway_id, gateway_ip, gateway_local_key, sub_device_id) and send_local_subdevice_commands(…) in tuya_controller.py — these pass the sub-device ID as cid to the gateway.
