Looking for a doorbird chime solution

Hi all,

I plan to use a Doorbird doorbell. I can be notified about someone ringing on my phone but I want an additional solution that rings independently. One solution within the doorbird universe is the DoorBird A1061W but I dont necessarily don’t want this € 170+ solution. I don’t have any permanently running media renderers, smart TVs and currently don’t own any Alexa, Google Home whatever.

What I am looking for is a cheap, low power chime that ideally runs without a cloud.

Do you have any ideas? My HA is running on a Raspberry Pi.

If the doorbird is replacing an existing doorbell & its chime is acceptable, i would activate it with a dry contact relay via an automation.
Option 2, ebay a chime & transformer of your choice.
