Smart Wi-Fi Energy Meter - See Exactly How Much Electricity You Are Using

Product description

Do you ever look at your T&TEC bill and have no idea which appliance or apartment is costing you the most?

If you rent out a room or apartment, how do you know how much electricity each tenant is actually using?

This smart energy meter fixes that.

It clips into your breaker box and starts tracking exactly how much power is being used in real time, all visible from your phone through the Tuya or Smart Life app.

Get daily, monthly, and yearly usage reports so you always know where your electricity is going.

Stop guessing. Start knowing exactly what your power is costing you.

Key features & benefits

• See your electricity usage live on your phone: Check voltage, current, and power consumption in real time from anywhere using the Tuya or Smart Life app.
• Know your daily, monthly, and yearly usage: The app keeps a full history of how much power was used each day, month, and year so you can spot patterns and cut waste.
• Perfect for landlords renting out in T&T: Set a prepaid electricity limit per unit so tenants get alerted when their balance runs low, making billing simple and transparent.
• Get alerts before something goes wrong: Set limits for voltage, current, and power so your phone gets a notification the moment something goes outside the safe range.
• Works with solar panels too: Tracks both the electricity coming in from the grid and any unused solar power going back out so you know exactly what your system is producing.
• Highly accurate readings: 99.5 percent accuracy means the number you see on your phone matches what is actually being used in your home.
• Export your data anytime: Download your full electricity usage history as a spreadsheet so you can review it, share it, or use it for billing calculations.
• Fits inside your existing breaker box: Compact design installs directly into your electrical panel without needing extra space or a separate enclosure.
