40A Wi-Fi Smart Switch for Water Heaters & Pumps

Product Description

Automate Your Water Heater and Water Pump Control

Replace manual power switches with a heavy-duty glass touch panel built for high-power appliances. Control your water heater or pump remotely from your phone, set automated schedules, and eliminate wasted electricity effortlessly.

Physical touch controls continue to operate manually even if Wi-Fi disconnects.

Top Highlights

• Safely handles heavy-duty electrical loads: 40A capacity supports high-power water pumps and water heaters up to 8000W.
• Dual-line safety cut: Uses dual Live and Neutral terminals (L-In, L-Out, N-In, N-Out) to disconnect both power lines completely when switched off.
• Control appliances from anywhere: Switch water heaters or pumps on and off remotely using the Smart Life or Tuya app.
• Hands-free voice commands: Just say "Alexa, turn on the water heater" or "Hey Google, turn off the water pump."
• Automate your daily schedule: Program custom timers so your water heater runs before morning showers and shuts off automatically to save power.
• Manual touch control always works: Touch buttons toggle power locally even if Wi-Fi or internet disconnects.
• Power outage memory: Choose how your switch behaves automatically when T&TEC power returns.
• Offline notification alerts: Get instant app notifications if the switch loses connection so you can act quickly.
