Wiring Requirements

If your home is older, verify your wiring before purchasing to avoid installation issues.

Always verify your wiring configuration before buying to ensure compatibility.

Consider which voice assistants and hubs you already use. Some switches work with Alexa and Google Assistant, while others support Apple HomeKit or Matter. If you plan to expand your smart home, look for switches that support Matter for better cross-platform compatibility.

Choose a switch that aligns with your existing smart home devices.

Ensure the switch supports the type of bulbs you have, such as LED, CFL, or incandescent. Different dimmers have specific wattage limits for LED loads, so check the specs to prevent flickering. Some switches offer adjustable settings to fine-tune performance with specific bulbs.

Confirm the switch supports your bulb type and wattage to avoid flickering.

Installation Complexity

Some switches offer app-guided installation with step-by-step instructions, making DIY easier. Look for features like color-coded leads or QuickFit designs that reduce physical complexity. If you are unsure, consult an electrician to ensure safe and correct installation.

Decide between Wi-Fi or hub-based connectivity based on your home network.

Control Features

Think about how you want to control your lights. Some switches support voice commands, while others work well with physical remotes like Pico. If you need multi-location control, look for 3-way kits or options that support secondary remotes.

Select control methods that match your daily habits.
