The Classe 300 EOS waits to "hear" a keyword (e.g. "Alexa"). This activates active recording by the device. If no keyword is detected, the device continues to record sessions of a few seconds in a continuous loop. All this happens locally in the device and nothing is sent to Legrand Netatmo Bticino or third parties. Only when the keyword is detected does the device, if activated, start recording and send the audio to Amazon. Data management (privacy) is governed by the terms listed on the Amazon.com website. Therefore, no voice recordings are processed by Legrand Netatmo Bticino.
