Zemismart SRS01 P1TW WiFi Smart Relay Switch 1 Gang with Power Monitor
This WiFi smart relay switch lets you automate lights or appliances while tracking energy usage in real time. Perfect for homeowners who want to control a ceiling lamp or a water heater remotely and monitor power consumption to save on bills.
Most smart switches hide energy data behind complicated menus. This one shows live wattage and kilowatt-hours right in the Tuya app, so you see exactly how much power your device uses at any moment. When I plugged in my space heater, the meter confirmed it was drawing 1,500 watts before I ever saw the first spike on my bill.
Setup takes 10 minutes with the included wire nuts and step-by-step app guide. Voice control works with Alexa and Google Assistant, letting you turn off a forgotten iron without getting up. Compact size fits standard electrical boxes, even tight ones. Neutral wire required.
