A:Answer If the entry sensor triggers an alarm, the siren is played ONLY from the HomeBase. You can receive a notification on your phone in addition to the siren that sounds from the HomeBase, but it would just be the phone notification sound and not a constant siren on your phone. The siren itself is not as loud as I expected it to be. We live in a two-story house and the siren can't even be heard downstairs. It's possible this could be remedied by having Echo Dots (or similar) connected to the HomeBase to trigger whenever an action occurs, but that's more things to purchase and integrate.
However, Eufy has been very good about updating the app (regular updates appear to be released about every two weeks or so), so it's possible the sound notification may be corrected in the future. From my research it sounds like Eufy would have to add/enable sounds in the app, and that those sounds could then be used for Eufy notifications.
