Tuya Water Heater Switch Smart Switch: High power 4000W voice control
This smart switch is designed for homeowners who want to upgrade traditional lighting or appliances without rewiring their entire house. While many smart switches focus on basic automation, this model offers something more valuable: real-time energy monitoring that helps you understand and reduce your electricity costs.
The energy statistics feature shows you exactly how much power your devices consume by day, week, or month. You can see if that old water heater is costing you more than expected, or track how much energy you save by scheduling lights to turn off automatically. With voice control through Amazon Alexa or Google Assistant, you can manage everything hands-free while cooking or carrying groceries. The two-way audio support in the app lets you hear if a device turns on unexpectedly, adding an extra layer of security. Installation is straightforward with neutral wire support, and the flame-retardant materials ensure safety for daily use in your home.
