Watt for Smart Devices

Complementary app to the universe TP-Link Smart home devices of Kasa Smart and Tapo.

:warning: If you are using mobile browser: Press the button "View all" to see all the page including the Roadmap!

Watt is an iOS mobile app developed for the TP-Link's Smart Plugs and Smart Lamps, that allows you to set cost for each kilowatt(kWh) and by doing this you have control of the cost in each device. Also, add support for voice actions using the "Hey Siri".

With this page of GitHub, I hope to develop a small community to report problems with the application and think of solutions.

Features

• Daily & monthly energy usage totals and averages and money cost.
• Historical daily and monthly energy usage charts and Runtime (hours that the device was on).
• Turn on/off the device
• Show cumulative energy usage form all devices.
• Support for Siri and the Shortcuts.
• One app supporting the both product lines Kasa and Tapo.

*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

Roadmap Server/Web

(The server still hasn't started the implementation much because of my lack of time, and lack of knowledge of server side-development)

• [ ] Send a weekly email with consumption reports and charts.
• [ ] 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.
• [ ] 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)
• [ ] Add Artificial Intelligence (IA) to detect and send you push notification when some consumption is not right like: leave the refrigerator door open, washer is done.
• [ ] 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.
• [ ] Monitor the voltage and if it is out of normal values send a warning or/and turn off the device
• [ ] Make web version

FAQ

1 - What is "Night Mode" functionality?

On all TP-Link plugs and switches there is a light to inform you that the device is active. The problem is that when the device is placed in the room it is annoying to have that LED active. With this feature, you can turn off that LED.

2 - How to activate the "Night Mode"?

To activate "Night Mode" you will have to follow these steps: Click on the button on the bottom right "▲". Click in one of the circles that will open a screen with information about your device. On that screen, you have a button on the top left for configuration, click on it. Now just go down and you'll find "Night Mode".

3 - Do all devices support "Night Mode"?

Almost all Kasa Smart devices are supporting, except: "HS200 v1", "HS220 v2" and the HS210 KIT(just the slave) I believe that is because of hardware limitations.

4 - Where is the Android App?

This app does not exist on Android and there are no plans for development. I'm just iOS Developer and I don't have knowledge of Android.

5 - There's a huge spelling mistake!

I'm not native english speaker! While this may sound like a bad excuse, it's legit. I'm doing my best to write understandable english, but I sometimes fail to notice an error. So again, if you happen to find a grammar or spelling mistake, just drop me a note and I'll correct!
