Installing a smart switch requires checking the wiring even before choosing the design. This is one of the purchases where compatibility errors are the easiest to make.
Mistakes to Avoid
1. Not checking for neutral wire
Some models require a neutral wire, others do not. The product sheet must be compared with your actual wiring.
2. Intervening without cutting off power
This is a major safety error. All electrical work must be done with the power off.
3. Ignoring supported power
A switch must be adapted to the type of lighting and the load it controls.
4. Forgetting box depth
Some modules or switches need space in the wall box.
5. Choosing Zigbee without a hub
A Zigbee switch often requires a compatible gateway.
6. Assuming Matter exposes all functions
Functions may vary depending on the controller, application, and model.
7. Installing alone despite doubt
If you are unsure about the wiring, it is better to consult a professional.
