Use a tp-link HS110 smart plug to see AER in action
Make your smart plug an emissions reducing hero
With the help of WattTime, any electricity-using, internet-connected device can automatically run at times when energy is
cleanest. We call this practice “Automated Emissions Reduction”. We pair AER with devices that don’t need a constant
supplyof electricity, like a thermostat, so you can use cleaner energy without any sacrices. However, for demo purposes,
you can use a smart plug that turns on and o in response to real-time emissions from your local grid to switch o a lamp
or other device.
Let’s Get Started
Step 1: Set-up two accounts
1. Kasa:
• Download and open the free Kasa Smart app from the app store on your smartphone.
• Follow the prompts to set up an account and connect your smart plug
• Ensure that in “Device Settings”, “Remote Control” is on
2. WattTime
• Open https://device.watttime.org in a web browser and sign up for an account
Step 2: Connect the accounts
• On https://device.watttime.org, hover over “Manage devices” and select “TP-Link” from the drop down options
• Fill out the TP-Link credentials form with the email and password of your Kasa Smart app account
• Check the permissions box to allow WattTime to talk to your TP-Link smart plug
• Click “Submit”
• The smart plugs you previously registered with the Kasa Smart app should now appear on the right of the page.
Refresh the page if they don’t.
Step 3: Set up the plug to run WattTime AER
• Check the “Control device with WattTime” box to reveal device options
• Select “General Purpose” and enter how aggressive you want to see the device respond the changing grid
emissions. The longer the window, the more opportunity for running on cleaner energy. A good middle-of-the-road
option is a minimum of 30 minutes of on time for a 60 minute duration.
• Enter the address where the device is located so that it responds to the local grid emissions.
Step 4: Plug it in
• Plug in a lamp and watch how grid cleanliness changes throughout the day
• You can also use the technology for how it’s intended, as a “set it and forget it” implementation with a phone or
computer charger or any other of the many devices that don’t need constant power.
• A detailed diagram of what you should see is shown on the next page.
