Always follow basic safety precautions when using your kettle. Read all instructions.

General Safety

  • CAUTION: Do not touch hot surfaces. Use the handle. Do not touch the heated parts of the base or the metal walls of the kettle during or immediately after operation.
  • CAUTION: Do not fill the kettle above the “MAX” line. This may cause water to boil over and may cause scalding.
  • CAUTION: To avoid scalding, always handle with care when there is hot water inside the kettle.
  • Do not immerse the kettle, base, cord, or plug in water or other liquids.
  • Closely supervise children near the kettle. Do not allow children to use or play with this kettle.
  • Unplug the kettle when it is not being used and before cleaning.
  • Allow to cool before putting on or taking off parts, and before cleaning.
  • Do not use the kettle if it is malfunctioning, or if any part, including the base, cord, or plug, is damaged in any way. Do not try to repair the kettle. Contact  Customer Support (see page 16).
  • Using accessory attachments not recommended by the manufacturer may result in fire, electric shock, or injury.
  • Do not use outdoors.
  • Place the kettle on a dry, flat, stable surface.
  • Do not place the kettle (including the base) on or near heat sources such as stovetops, ovens, radiators, etc.
  • To avoid scalding, always make sure the lid is securely closed while the kettle is operating. Do not cover the spout opening while the kettle is in use. Do not cover the openings on the lid.
  • To disconnect, press CANCEL to turn the kettle off, then remove the plug from the wall outlet.
  • Only use the kettle as directed in this manual.
  • Household use only.

Power & Cord

  • Do not let the cord (or any extension cord) hang over the edge of a table or counter. Do not allow the cord to touch hot surfaces.
  • This kettle has a 3-prong grounding plug. Always plug into a grounded electrical outlet. Do not modify the plugin anyway.
  • This kettle uses a short power supply cord to reduce the risk of entangling or tripping. Use extension cords with care.
  • Any extension cord must also be a grounding-type 3-wire cord.
  • The marked electrical rating of an extension cord should be at least as high as the rating of the kettle. (see page 2)

Note: If the electrical circuit is overloaded with other appliances, your kettle may not operate properly. Operate it on a separate electrical circuit.

Water Test

Perform the Water Test before using your kettle to make sure it’s working properly.Do not drink the water that is boiled during this test.

  1. Remove all packaging from your kettle and its accessories.
  2. Completely unravel the power cable and place the power base on a flat, level, stable surface.
  3. Fill the kettle with water to the “MAX” line, then put the lid on the kettle. Press firmly to make sure the lid fits securely.
  4. Press 212°F (“BOIL BLACK”).
  5. The kettle will automatically turn off once it has finished boiling the water. Allow it to cool, then pour out the water. Rinse thoroughly 2–3 times with cold water.
VeSync App Setup
  1. To download the VeSync app, scan the QR code or search “VeSync” in the Apple App Store® or Google Play Store.
  2. Open the VeSync app. If you already have an account, tap Log In. To create a new account, tap Sign Up.
  3. Follow the in-app instructions to finish setting up your smart kettle.



  • Use filtered water for perfect pour-over brewing.
  • If you start the kettle without water in it, the kettle will turn off and controls will be disabled. See Boil-Dry Protection (page 11).
  1. Add at least 118 mL / ½ US cup of filtered water to the kettle. Do not fill above the “MAX” line. Wipe any water from the outside of the kettle and the base.
  2. Put the lid on the kettle and make sure it fits securely. Place the kettle on the power base.
  3. Plug in the cord. The button lights will blink, and the base will beep once.
  4. Press a preset temperature button. The button will light up, and the kettle will start heating up the water.Note:• You can only select 1 preset at a time.
  5. Optionally, press (“HOLD TEMP”) any time before the kettle is finished heating. This will turn on Hold Temperature Mode, which will automatically keep the kettle at the same temperature for 30 minutes after heating is finished. The button will stay lit during that time.


  • The Hold Temperature time can be changed from 5–60 minutes in the VeSync app. (“HOLD TEMP”) will not turn on unless a preset is selected.
  • If you take the kettle off the base while Maintain Hold Temperature Mode is activated, the (“HOLD TEMP”) button will blink. After 60 seconds, the kettle will turn off.
  • Press and hold for 5 seconds to turn Always Hold Temp on/off. When Always Hold Temp is on, Hold Temp Mode will automatically turn on whenever you select a temperature preset.

6. When the water reaches the selected temperature, the kettle will beep 3 times and stop heating.

Making Pour-Over Coffee

You’ll need a pour-over coffee maker, such as Cosori’s Original 8-Cup Pour-Over Coffee Maker.

  1. Place the coffee maker filter into the decanter.
  2. Add ground coffee to the filter according to your preference.
  3. Heat water using the smart kettle.
  4. Use the kettle to gently pour water over the coffee grounds using a slow spiral motion. Pour just enough water to saturate the grounds.Note:• This spiral motion is to create “turbulence” in the coffee grounds, allowing the particles in the coffee to separate and release flavour.• The water will cause the grounds to puff up, which is called “blooming”. Some roasts will bloom more than others.
  5. Wait 30–45 seconds.
  6. Use the kettle to pour water over the coffee grounds again using a slow spiral motion. If water reaches the top of the filter, stop and let it settle to the halfway point, then begin pouring again until you have the desired amount of coffee.
  7. When finished, remove the filter and enjoy!
High Altitude Users

At higher elevations, water boils at a lower temperature. You may need to use a different preset.

Altitude Preset for Boiling Water
1,183–2,820 m / 3,881–9,255 ft 205°F COFFEE
2,821 m / 9,256 ft and above 195°F OOLONG
Smart Kettle Sounds

The kettle will alert you by beeping 3 times when the water reaches the preset temperature. The alerts can be turned off in the product settings on the VeSync app. The kettle will also beep once when plugged in or when boil-dry protection is activated.

Boil-Dry Protection

Your kettle is equipped with boil-dry protection. If there is less than 118 mL / ½ US cup of water in the kettle, the heat will automatically shut off. Allow the kettle to cool, then add more water before using again.If all buttons blink and the kettle beeps, remove the kettle from the base and let it cool.

Adjusting Lid Tightness

If you feel the kettle lid fits too loosely or is too hard to take off, you can adjust the tightness of the lid.

  1. Take off the lid.
  2. Use a tool to adjust the 3 tabs on the kettle lid. [Figures 1.1-1.2]a. If you push the tabs in, the lid will fit more loosely, and will be easier to put on and take off.b. If you pull the tabs out, the lid will fit more tightly, and will not come off as easily.
  3. After adjusting the tabs, put the lid back on and take it off again to see if the fit is correct. If not, adjust the tabs again until the lid fits the way you prefer.

  2. Wipe the kettle and base with a soft, damp cloth. Make sure that the electric socket on the underside of the kettle is kept dry.
  3. Dry all parts after every use.Note: Never immerse kettle or power base in water.
Descaling the Smart Kettle

You should descale the kettle at least once a week if you use it frequently. Descaling removes any mineral deposits that have built up inside the kettle. Always descale the kettle before and after storing for long periods of time.

1. Unplug the kettle and pour out all water. Make sure the kettle is cool.2. Squeeze half a lemon into the kettle, or add 118 mL / ½ US cup of distilled vinegar into the kettle.3. If the kettle has thick scale buildup, scrub the kettle’s inner walls with a nonscratch scrub sponge.

Note: Do not use steel wool, as this can scratch the kettle.

4. Add 473 mL / 2 US cups of water. Boil the mixture.5. Pour out the mixture, then wipe off any remaining scale with a non-abrasive cloth, sponge, or cleaning brush.6. Repeat as needed.

Note: For quick descaling, add 44 mL / 3 US tbsp of baking soda to 118 mL / ½ US cup of vinegar into the kettle. Swirl the mixture around until it coats the walls of the kettle, wipe with a non-scratch sponge, and pour the mixture out. This method will only work for a thin layer of scale.
