Tuya Smart WiFi Switch for Water Heater: Remote control via app and voice (Alexa/Google)
This smart Wi-Fi switch is for homeowners who want to control their water heater remotely, like turning it off after a vacation to save energy. While many focus on home automation, this switch offers peace of mind by preventing accidental overheating and reducing electricity bills.
You can set a timer in the app to run the heater only during off-peak hours, and the energy monitoring function shows real-time usage so you adjust habits. The two-way design ensures safe disconnection, and the RF remote works up to 100 meters outdoors if your phone loses signal. It integrates with Alexa and Google for voice commands, letting you check status hands-free. The app displays current status instantly, so you always know if the heater is on without guessing.
