Tuya Smart WiFi Switch for Water Heater: Works without neutral wire
This smart Wi-Fi water heater switch is for the homeowner who wants to save energy and gain control over their hot water usage. While it enhances home automation, its real value is in giving you peace of mind by preventing unnecessary heating when you're away.
Install it easily without a neutral wire, and use the timer to schedule heating only when needed—like turning it on an hour before you wake up. The touch panel feels smooth and responsive, and the backlight clearly shows if it's on or off. Control it remotely via the app or with voice commands through Alexa, so you can adjust settings from anywhere without a second thought.
