🔑 Getting API Keys (Access ID & Secret)

Click Open Project and navigate to the Overview tab. You will find two values:

Access ID — the API Key for Power Trace
Access Secret — the secret key for authorization

Enter both into Power Trace Settings → Tuya Cloud section.

🔐 In Power Trace these values are stored encrypted and shown only as masked (••••XXXX) on next open.

📋 Getting the Device ID

Navigate to:

Cloud→Devices→All Devices

Find your device and open it. You will see:

Device ID — the unique device identifier
Device Name — the device name

💡 In practice the Device ID is retrieved automatically via Scan Devices in the next step.

⚡ Getting Local Key & IP via Power Trace Settings

Make sure the API is running and open Power Trace Settings:

Expand the Tuya Cloud section
Enter Access ID and Access Secret from step 3
Click Scan Devices

When the device list appears — select your device and click Use This Device.

⚠ Do not forget to click Save Configuration after selecting a device. Access Secret and Local Key are stored encrypted and will not be shown in plain text on next open. Local keys can change when a device is re-paired or its firmware is updated — if a device stops responding, re-run Scan Devices.

Device ID, IP and Local Key auto-filled

🔧 Alternative: Local Key via API Explorer & IP via Router

💡 Use this method only if Scan Devices (step 6) did not work, or if you want to retrieve credentials manually without running Power Trace.

Getting the Local Key via API Explorer

After completing steps 1–5, open API Explorer in your project:

Cloud→API Explorer

Opening API Explorer — Cloud → API Explorer

In the search field type Query Device Details and select it from the list
Enter the Device ID from step 5 into the device_id field
Click Submit Request

Searching for Query Device Details in API Explorer

Search for Query Device Details in API Explorer

Entering device_id into the request field

Enter the device_id value and click Submit Request

In the server response find the local_key field:

{
"result": {
...
"local_key": "xxxxxxxxxxxxxxxx",
...
}
}

API response — find the local_key field

Copy the value of local_key and enter it into the Local Key field in Power Trace Settings.

Getting the IP Address via Router

If Scan Devices could not find the device IP automatically, look it up in your router’s admin panel.

Step 1. Open the router web interface in a browser:

Common addresses:http://192.168.0.1

http://192.168.1.1

Step 2. Find the connected devices list. Depending on your router it may be called: Connected Devices, Client List, DHCP Clients, LAN Clients, Device List, Attached Devices, Network Map, Online Devices.

Step 3. Locate your Tuya device by name, MAC address, manufacturer (Tuya, ESP, Realtek, BK7231), or last connection time.

Step 4. Note the local IP address, e.g. 192.168.0.114, and enter it into the IP Address field in Power Trace Settings.

✅ Tip: to prevent the IP from changing after a router reboot, assign the device a static IP. Look for DHCP Reservation, Address Reservation, Static DHCP, Static Lease, or Bind IP to MAC in your router settings, and bind the device’s MAC address to its current IP.
