Q: When the sensor detects an opening in the armed mode, where are sirens deployed? To only the sensor itself? Or also the HomeBase? Also, can an alarm be sent to your phone (not just a notification). I'd want to make sure I hear an alarm while asleep.

A: 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.

Q: How do I get the home base. Amazing how hard it is to figure this out. Maybe this should be mentioned up front and the base be available at best buy. Typical of todays companies and we are not off to a good start.

A: Eufy home base comes with other Eufy home security items like outdoor camera and doorbell. If you look at some of the items listed at BestBuy website, you will be able to see them in the product description.

Q: Is eufy compatible with google nest ? Can the window and door sensors be connected to google nest and where would the alarm sound? Can eufy video doorbell with storage base be connected to googlenest

A: This Entry Sensor is compatible with google nest. It supports using google nest hub as an alarm. The Doorbell also supports google nest hub.

Q: WHAT POWERS BOTH EUFY SECURITY ENTRY SENSOR DEVICES?

A: The Eufy entry sensor is power by a battery (come with) on the larger sensor. The smaller piece does not need power. It is an encapsulated magnet since this is a Reed switch.

Q: I have a eufy door bell camera already. Does the door sensor work with it? Do I have to purchase a home base for the door alarm?

A: The entry sensor only work with a home base which the door bell do not. But the Eufy can manage both devices in one place.

Q: Can the alarms be set to trigger at night only through the app?

A: Not directly, but with help of eufy security keypad. Multiple devices like eufy cameras and sensors can be added to the Security keypad and then set alarm to activate when you are away from home or in night mode.

Q: After mounting the eufy door sensor, how do I turn the siren off while I’m home? Also how do I turn the siren back on?

A: You can turn it on or off via eufy Security APP.

Q: Hiw can I make the alarmin my phone app louder so I can know when a human is near.

A: You can turn up the volume of your phone.

Can't go wrong
These sensors are small, reliable, easy to set up, and look nice and modern. Just put the battery in, spend 30 seconds pairing with the Homebase and assigning it a name, then stick the two parts on your door/window and frame. It's a nice way to supplement a couple of Eufy cams since the cams' motion/human detection is maybe 90% reliable. Be sure to use the Eufy app to customize when you want to receive notifications and alarms. I have mine set so they don't send any notifications when our system is in Home mode, but will alarm when in Away mode. If you have a lot of sensors or modes, it's annoying to configure the settings one-by-one in the app, but you'll probably only do that once or twice anyway. The adhesive backing is very strong, so make sure of where you want to place them, then position carefully. I'm sure they'll pull up the paint when I want to remove them, so if you're worried about that, maybe attach them to Command strips first. (Just remember that if the adhesive is too weak and they fall down, your alarm might go off.) I haven't owned them long enough to comment on battery life, but the rest of the process is incredibly straightforward, and I think these are a good deal when they're on sale.
