5. Setup and Installation

5.1. Wiring the Smart Switch

Before proceeding, ensure the main power supply to the circuit is turned OFF at the breaker to prevent electrical shock. The TH-16 Smart Switch requires a live (L) and neutral (N) input, and provides a switched live (L) and neutral (N) output to your appliance.

1. Identify the Live (L) and Neutral (N) wires from your power source.
2. Connect the Live wire from the power source to the "IN L" terminal on the switch.
3. Connect the Neutral wire from the power source to the "IN N" terminal on the switch.
4. Connect the Live wire of your appliance to the "OUT L" terminal on the switch.
5. Connect the Neutral wire of your appliance to the "OUT N" terminal on the switch.
6. Plug the DS18B20 temperature sensor into the designated port on the smart switch.
7. Secure all wire connections firmly.

Warning: Incorrect wiring can cause damage to the device or electrical hazards. If you are unsure, consult a qualified electrician.
