Yes, the 2K battery doorbell uses a HomeBase speaker as a chime. Sorry that there is no remote chime in the package like other eufy wired doorbells. 
 

1. If you have existing doorbell wires and chime, the battery doorbell can be hardwired and control the existing chime. 

2. If you have Alexa Echo devices, the doorbell can also link to Alexa and make it work as a chime.

3. If you want a second chime to install it at a different place, you can purchase an add-on chime with a USB dongle, which is designed for the Homebase 2. This add-on chime is available in <a href="https://www.amazon.com/dp/B08C9J1X2R" target="_blank">US</a> and <a href="https://www.amazon.co.uk/dp/B08FB38KTK" target="_blank">UK</a> markets now.
