Yes, it is important to always observe safety guidelines when using a Smart plug with devices that require a high current or power.

Important safety precautions:

1. Check the maximum power
   Check the manual or the packaging of the Smart plug for the maximum power (Watts) or maximum current (Amperes). Never connect devices that exceed this.

2. Avoid continuous high load
   Devices with a high current demand, such as heaters, kettles or large kitchen appliances, can heavily load the plug. Do not use these devices continuously via the Smart plug.

3. Watch for heat development
   Regularly check whether the Smart plug does not become too warm. If it overheats, disconnect it from the socket immediately.

4. Use a grounded socket
   For devices with high loads, it is recommended to use the plug in a grounded socket to ensure extra safety.

5. Follow the manual
   Always consult the included manual of the Smart plug for specific safety instructions and warnings.

Tip: Most household appliances can be safely used via a Smart plug, as long as you do not exceed the maximum power. If in doubt about a device with a high load, it is better to check the specifications first.
