Before choosing a model, you should consider three important questions:

3. Do you need regional certification?

This guide will help you select the right Zemismart 606 smart switch.

1. First Step: Check Your Wiring Type

Option A: Neutral Wire Available (Recommended)

If your wall box has:

• Live wire (L)

• Neutral wire (N)

• Load wire

You should choose a Neutral Wire Version.

Advantages:

✓ More stable power supply
✓ Better compatibility with LED lights
✓ More reliable operation
✓ No need for standby current through the lamp

Neutral wire switches are recommended for new houses, modern electrical installations, and professional smart home projects.

Option B: No Neutral Wire Available

If your wall box only has:

• Live wire (L)

• Load wire

You need a No Neutral Wire Version.
