After you have plugged in the Qi Aerista IoTea Brewer, a beep should sound. To turn the brewer on, please long press the BREW button on the base for 2 seconds until the light on one of the tea types illuminates ("Black" by default) and another beep sounds.
Afterwards you can proceed to normal brewer operations including linking to your app. You can refer to page 6 section 13 of our user guide for more details.
In case if no beep is heard after you have plugged in the Qi Aerista Smart Brewer, please try plugging it again into another power socket. If it still doesn't work, please contact us at firstname.lastname@example.org for further assistance.
