Eufy Wireless Doorbell not working in wired mode

Hello guys and gals.

I have recently purchased a wireless doorbell and wanted to connect it to my current wires that I had for old doorbell manual chime. These wires are 8V and I have checked that everything is still working using my old push doorbell and also using a voltmeter.

When I connect the eufy Wireless doorbell the indoor chime works on the first press of the eufy doorbell. Any subsequent presses do not cause the manual chime to work. Also using the app I can see that the doorbell is being powered by the battery and not the connected wires.

Can anyone help please?

What’s the amperage on the wires?

You are going to need about 20 volts for the doorbell to work in the wired mode.
