Simple & effective way to control your Kasa Smart devices


Watt offers a wide range of Unique Features

This list is always growing

Night Mode

Turn off all the LEDs of your Smart Device. The lights are turned off but the system continues to function normally so you can have a restful night's sleep.

Daily and Monthly Chart

We generate graphs bar for easy reading of consumption, costs and how many hours the device was turned on.


Erase Statistics

The ability to reset the stats for when a different appliance is plugged in and I want to start fresh. Without you having to restart your smart device.


Use Siri to turn On or Off your devices or know the current status of the device. You can also control a group of devices that are in the same space and turn them all On of Off at once.


Watt, it was developed with the HS110 HS300 in mind but we also supports all Kasa models but with some limitations because those devices don't have energy monitoring capabilities.

Featured HS100, HS103, HS105, HS107, HS200, HS210, HS220, KP105, KP200, KP303, KP400 HS110, HS300 KL50, KL60, KL110, KL120, KL130, LB100, LB110, LB120, LB130, LB200, LB230

    This is strategic and long-range planning for this app. For many of the features that are planned beyond the mobile application, we will need to develop a server-side.

    • Show cumulative energy usage form all devices.
    • Show energy consumption by the last 30 days, month.
    • Show daily cost metrics
    • Night Mode (Option to turn off the led light).
    • Show more info about each device (Like real-time consumption, Voltage, wireless signal).
    • The ability to reset the stats for when a different appliance/device is plugged in and I want to start fresh.
    • Create a concept "Room/Spaces" which will aggregate multiple devices.
    • Uses voice commands to turn on/off device using Siri shortcut.
    • Add support to TP-Link HS300, KP200, KP303, KL50, KP400, HS107, KP100.
    • Add support to Smart Bulb KL50, KL50B, KL60, LB200, LB230(E26), LB230.
    • Implement Haptic Touch
    • Export the data to Excel (csv)
    • Show chart gathering all devices and the total cost.
    • Record the energy consumption hour by hour.
    • Show energy consumption by day, bill.
    • The option to define peak and off-peak times and electricity prices.
    • Send a weekly email with consumption reports and charts.
    • Calculate the energy cost for smart switches (HS200, HS210 and HS220) based on Runtime + default/set value consumed energy.
    • Force reboot, turn Off device then On after 30 seconds turn on again (Helpful for devices like wifi routers connected to the smart plug)
    • Make smart action (like if consumption is lower then specific value turn off(stand-by), or using GPS and when arriving home turn on the light, even use the weather forecast to make action, define amount time before sunset/sunrise action)
    • Make a personalized schedule that will tell you how much money you will save by turning off your device x hours
    • Set Goals to save energy
    • Add Artificial Intelligence (IA) to detect and send you push notification when some consumption is not right like: leave the refrigerator door open, when the machine finished washing.
    • If you have multiple devices connected to single HS110 use artificial intelligence to detect which devices are turned on and off and how much each one of them is spending.
    • Add support to Tapo P100 (encryption protocol is is different and I can't get it to work).
    • Make web version

    App is free developed with ♡ for TP-Link community, download app today!
