Introduction
The Ember Temperature Control Smart Mug 2 is designed to keep your beverages at your preferred drinking temperature. This manual provides essential information for setting up, operating, maintaining, and troubleshooting your smart mug to ensure optimal performance and enjoyment.
Key Features:
- Perfect Temperature Everytime: Maintains beverage temperature between 120°F to 145°F for up to 80 minutes on battery or all-day on the charging coaster.
- Smart or Standalone Operation: Use the Ember app for precise temperature control and notifications, or use the mug standalone with a default temperature of 135°F and memory for your last setting.
- Auto Sleep & Sensors: Automatically wakes when hot liquid is poured and enters sleep mode based on motion detection to conserve battery.
- Hand Wash Safe: Designed for easy hand washing with a scratch-resistant coating and fully submersible up to 1 meter. Not dishwasher safe.
- Smart LED Indicator: An LED light indicates when your drink has reached the desired temperature.
Setup
- Unpack the Mug: Carefully remove the Ember Smart Mug 2, charging coaster, and power adapter from the packaging.
- Charge the Mug: Connect the power adapter to the charging coaster and plug it into a power outlet. Place the mug onto the coaster. The LED on the mug will indicate charging status (pulsing light). Ensure the bottom of the mug is dry before placing it on the coaster.
- Download the Ember App: Download the Ember app from your smartphone's app store (iOS or Android).
- Pair with the App: Open the Ember app and follow the on-screen instructions to pair your mug. This allows you to set custom temperatures, receive notifications, and manage settings.
- Initial Use: Once charged and paired, fill your mug with your desired hot beverage. The mug will automatically detect the liquid and begin heating to your set temperature, or the default 135°F if not connected to the app.

Operating Instructions
Setting Temperature:
- Using the App: Open the Ember app, select your mug, and use the temperature slider to set your desired drinking temperature. The mug will adjust accordingly.
- Standalone Use: Without the app, the mug defaults to 135°F (57°C). It remembers your last used temperature setting if previously set via the app.
LED Indicator:
The LED light at the base of the mug provides visual cues:
- Pulsing White: Heating or cooling to target temperature.
- Solid White: At target temperature.
- Pulsing Red: Low battery.
- Solid Green: Fully charged.
- Solid Red: Error (refer to troubleshooting).

Auto Sleep Function:
The mug features an auto-sleep function. It will wake up when it senses liquid or motion and go to sleep when empty or inactive for a period to conserve battery life.
Maintenance
Cleaning Instructions:
- Hand Wash Only: The Ember Smart Mug 2 is designed for hand washing. Do not place it in a dishwasher.
- Submersible: The mug is fully submersible up to 1 meter. You can rinse or soak it for cleaning.
- Drying: Ensure the bottom of the mug is completely dry before placing it back on the charging coaster to prevent damage to the charging contacts.
- Avoid Abrasives: Do not use abrasive cleaners or scrubbers that could damage the scratch-resistant coating.

Troubleshooting
| Problem | Possible Solution |
|---|---|
| Mug not heating liquid. | Ensure the mug is charged. If pouring room temperature liquid, the mug may not detect it as 'hot' to activate heating. Try pouring pre-heated liquid or manually activating via the app if available. |
| App connectivity issues. | Ensure Bluetooth is enabled on your device. Try restarting the app and the mug. If issues persist, unpair and re-pair the mug in the app settings. |
| Short battery life. | Battery life is up to 80 minutes off the coaster. For all-day warmth, keep the mug on its charging coaster. Ensure the charging contacts on both the mug and coaster are clean and dry. |
| LED shows solid red. | This indicates an error. Try resetting the mug by holding the power button on the bottom for 3 seconds. If the error persists, contact Ember customer support. |
