How many entry sensor can be connected to home base?

In theory, one Homebase 2 can add at most 16 sensors. The actual quantity will vary depending on a number of factors such as the installation place, the Internet connection, and the location of the router.

It ring when the door is open

You will get notified on your mobile , you can put settings to away when leaving the house and the alarm will go on when somebody opens the door

Does it work with Alexa

Yes, it is compatible with Alexa.

Where can i buy a separate homebase unit? I do not require cameras just door security sensors

It’s cheaper buy a base with two cameras you might use them one day

Simple but great

Integrated well with existing Homebase 380 - I even accidentally installed the magnet on the wrong side of the sensor (reading the instructions highly recommended) and works fine. Just note it’s not perfect - can show as “closed” even if the door is not fully closed.

Quick, simple and hassle free

Product came in good packaging and was delivered as advertised. Easy to setup and install. Connects with the Homebase and allows automation triggers in the Eufy Security app.
