Watt, was developed with the objective of reaching the largest number of Smart Home(plugs & bulbs) devices of the product line Kasa Smart and Tapo brand. Not all devices have the same hardware capabilities.

  • *1 Due to hardware or firmware the HS200 v1 and HS220 v2 the night mode does not work. It's working well for HS200 v2 and v3 and HS220 v1 and v3 and all the other devices.
    If you are using the HS210 KIT and you can only activate Night Mode on one of the devices, check this solution from the user @elitepuckster: Solution for the HS210 KIT
  • *2 For Kasa Smart Switch for HS200, HS210, HS220, KS230 and KS220M we are calculating consumption based on the number of hours the device it's running + the default value set by the user. Read more

    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.
